below is a list of all attacks in Dragonball

12 Eyes (AKA Shishin no Ken or the Multiple Images)
This technique is used by Tenshinhan to split himself into four different parts. Each Tenshinhan created is not just an image like that created with the Zanzoken, but can fight and be attacked. The only problem with the 12 Eyes move is that each Tenshinhan only has a quarter of the power and the speed than if there was only one.
Who can use: Tenshinhan, Cell

Bakuhatsuha
By raising two fingers, the user of this attack can create a large explosion that will totally decimate the surrounding area or the ground under an opponent.
Who can use: Napa, Vegeta

Barrier
This purely defensive technique forms a Ki-shield around the body that protects the user from Ki or similar attacks. There are two forms of this maneuver. One is a spherical shield that surrounds the body, the other is more of a coating of the body.
Who can use: Freeza, #17, Cell, Vegeta

Big Bang Attack
One of the first techniques Vejiita developed as Super Saiya-jin, the Big Bang attack is a huge ki bolt of incredible destructive power. Vejiita holds one flat palm forward towards his enemy and launches the bolt. The attack that took out #19.
Who can use: Vegeta

Body Change
This technique is used by the leader of the Ginyu-tokusentai, Ginyu. Ginyu spreads his limbs out, shouts "Change!" and shoots out a bolt of energy, and if it hits its target, Ginyu changes bodies with that person. Ginyu then gains the strength and speed of his target, but not his special techniques or ki. After changing bodies, Ginyu can still do a Body Change. Ginyu will change bodies with the first person to hit his change beam, and thus if someone gets in the way of his intended target, Ginyu will change bodies with that person instead.
Who can use: Ginyu

Bukujutsu
Not exactly a fighting technique, this is the ability to fly with one's ki. Since almost all of the fights in the second series occurred at least partially in the air, this technique is used all the time during fights, as well as being used to go from place to place. The only characters in the first series that could use it since their first appearances were Tenshinhan, Chaozu, and Piccolo. (and maybe Pooalu?) Almost every one of the other characters learn to fly eventually, and by the time DBZ comes around, every major character could.
Who can use: Anyone who fights in DBZ except Yajirobe and Mister Satan.

Burning Attack
Future Trunks' trademark ki attack, this is a powerful energy blast shot from both hands. Trunks holds both hands forward, does some strange arm moves, and then puts both hands forward again, index fingers and thumbs touching. Then he releases the blast.
Who can use: Future Trunks

Chaozu's Chonoryoku
A very unique technique, Chaozu puts both hands, or a single hand forward and can manipulate the bodily movements of his opponent to an extent, providing his opponent is not too powerful. He can stop someone's movements or cause internal pain with this technique.
Who can use: Chaozu

Chobakuretsumaha
This is Piccolo's ultimate Ki blast. He powers up the blast between the palms of his hands in front of his chest, then releases the blast. Very very powerful. This blast is known as "Gekiretsukodan" in the DBZ video games.
Who can use: Piccolo

Crasher Ball
A lot like the Genki-dama that Gokuu gave to Kurilin, the Crasher Ball is a ki-ball that is produced from the palm of the hand. I don't think one ever actually connected during the series though, it was just used as a diversion.
Who can use: Jace

Daichiretsuzan
This is a very powerful attack that Freeza uses. With a swipe of his hand with two fingers extended, he creates an invisible cutting beam that goes a long way. Its name comes from the fact that it slices a huge cut in the earth when he uses it.
Who can use: Freeza

Death Ball
This is a small ball of energy which Freeza can create from either the tip of his finger or with both hands. While small, it is very powerful, and can even destroy planets.
Who can use: Freeza

Dodonpa
One of the major techniques of the Tsurusennin, this is a blast shot from one finger, which explodes upon impact. The most basic Dodonpa is more powerful than the most basic Kamehameha, but the Kamehameha can become more powerful. After being defeated by Gokuu, Taopaipai develops this technique into the Super Dodonpa. I don't think this technique was ever used after the first series.
Who can use: Chaozu, Tenshinhan

Double Tsuihikidan
This is a move that Kurilin developed for use during the 23rd Tenkaichi-Budoukai. He shoots a Kamehameha-like blast from each hand, then can guide the blasts toward his enemy.
Who can use: Krillin

Dynamite Kick
Mister Satan's trademark attack. A charging kick. Being one of Mister Satan's attacks, this one is pretty much useless. Gotenks used it once too, (whether or not he was copying Satan is debatable) and it was likewise useless.
Who can use: Mister Satan, Gotenks

Enemy transformation
By shooting an energy field from his head-appendage, Majin-Buu can change the form of his enemy into something else, normally candy or some other form of food, by saying "[insert item here] ni natchae!" (Fat Buu) or "[insert item here] ni nare," (Super Buu) literally meaning, "become a [insert item here]" This is without a doubt Buu's most common attack.
Who can use: Majin-Buu

Energy Kyushu
The trademark technique of #19 and #20. The Artificial Humans can absorb energy, either from people's bodies or their ki blasts, through the holes in the palms of their hands. However, without their hands, they cannot perform this technique.
Who can use: #19, #20

Eraser Cannon
This is one of the most powerful techniques of Racoom, one of the members of the Ginyu-tokusentai. It is a large, powerful Ki blast shot from the mouth, and can destroy in a very large radius from where it hits.
Who can use: Racoom

Eye Beam
Not a particularly interesting technique, but was used enough during the DB/DBZ series that it deserves to be put here. It is basically a double ki blast shot from the eyes. While the blast itself is small, it explodes on impact to do a fair amount of damage, and can also be used to stop other ki blasts.
Who can use: Piccolo, Freeza, #20

Freeza Beam
This is Freeza's trademark technique. It is a lot like the Dodonpa, being a beam of energy shot from one finger, but differs in that it does not explode on impact. Instead it is a piercing attack which continues through its target and can also be used to slice.
Who can use: Freeza, Cell.

Fusion
This technique is used to fuse two people into a single person, and give the fused person a huge power boost. Anyone can do the Fusion, but you have the same power as whoever you fuse with, and you must learn the correct pose and form. It's easy to make a mistake and fuse into something far weaker though. The Fusion lasts for 30 minutes before the fused person becomes two again. 15-Dai Kaioshin has a special set of Potara (earrings) which allow people to fuse without the pose, and that lasts forever. Son Goku and Piccolo know how to do it without the Potara but never actually did the move.
Who can use: Goku and Vegeta, Goten and Trunks

Fusenko
This is a move used by Kurilin during the 22nd Tenkaichi-Budoukai. Kurilin draws in his breath while falling down, puffing himself up and slowing his fall. Can be used to gain a good defensive advantage.
Who can use: Kurilin

Galactica Donut
This is a ki attack used by Gotenks used to trap enemies. It is a ring of ki energy that Gotenks can control to change size of the diameter of the donut. The Donut can be used to surround the enemy and trap him by holding his limbs with the donut. Super Saiya-jin 3 Gotenks can use an adaptation of this attack, the Renzoku Super Donuts.
Who can use: Gotenks

Galick-Ho
The Galick-Ho is Vejeta's answer to the Kamehameha. He powers up the blast like the Kamehameha, but when he releases the blast, his hands are both palm-forward.
Who can use: Vegeta

Gekitotsu Buu Volleyball
A unique attack used once, by Gotenks and Piccolo. After trapping Buu in a ball with Renzoku Super Donuts, Gotenks and Piccolo beat the ball around a bit before spiking it really hard into the earth.
Who can use: Gotenks and Piccolo

Genki-dama (Spirit Bomb)
One of Gokuu's most powerful techniques, the Genki-dama is a large ball of energy gathered from nature, humans, etc., which lend him their energy. However, it takes time to gather a Genki-dama, and has to stick his arms up in the air, during which time Gokuu is open to attack. This attack is used sparingly because of the amount of energy need to make it.
Who can use: Goku

Gotenks' Ultra Kicks, Punches, Headbutts, etc.
These attacks are not particularly special, just punches and kicks that Gotenks made up names for on the spur of the moment. Their names are: Rolling Thunder Punch, Inoshishi (Wild Boar) Attack, Power Tackle, Great Kick Special, Magnum Sundae, Ultra Missile Parfait, and Hyper Plasma Shortcake. None of them are particularly useful, at least not in the fight in which they were used.
Who can use: Gotenks

Haikyuken
A technique used against Gokuu by Tenshinhan in the 22nd Tenkaichi-Budoukai. Tenshinhan treats his opponent like a volleyball and hits him around volleyball style. (Note: See the episode with this technique if you get a chance. Tenshinhan's falsetto is a riot!)
Who can use: Tenshinhan

Hankokubikkurisho
This is a fairly strong ki attack used by Jacky Chun (Mutenroshi) He shoots the blast forward using both hands and traps his victim in a shocking field of energy from which his opponent cannot escape (normally.) This technique was only used in the 21st Tenkaichi-Budoukai.
Who can use: Master roshi

Haretsu no Maho
This is the magic spell used by Babi-di to make people explode. It only works on weak people though; on tougher fighters like the Z fighters it is ineffective.
Who can use: Babi-di

Hasshuken
Inspired by Tenshinhan's Shiyoken, and Chapa-oo's move of the same name, Gokuu moves his arms fast enough so there are like eight, and he attacks with all eight at once.
Who can use: Son Gokuu, Chapa-oo

Hell's Flash
In order to fire a blast with the most power, #16 takes off his hands, tucks them under his arms, and fires a powerful blast from the cannons under his wrists.
Who can use: #16

Honoo
Not a particularly important technique, but this is one of Dabura's more powerful blasts. It's just what it says, a powerful breath of fire.
Who can use: Dabura

"Invisible" Jumping
First used against Kurilin in the second Tenkaichi-Budoukai that we see, Gokuu uses this attack to become "invisible." He jumps back and forth so fast that you cannot see him, then he stops jumping for a surprise attack.
Who can use: Son Gokuu, and probably Kurilin, since Gokuu said he would teach him

Jan-Ken Punch
"Jan-ken-pon" is a Japanese game identical to that of "Rock, Paper, Scissors." Gokuu then has three different types of Jan-Ken Punches:
· Jan-Ken-Gu: Corresponding to "Rock," "Gu" is a strong punch to the face.
· Jan-Ken-Choki: Corresponding to "Scissors," "Choki" is an eye-stab with two fingers.
· Jan-Ken-Pa: Corresponding to "Paper," "Pa" is an open-handed slap to the face.
Who can use: Goku Jinruizetsumetsukogeki
Literally "Genocide Attack," this is not an attack that can be used in the heat of battle but is probably one of the single most devastating attacks ever used in the DB/DBZ series. It is a series of ki blasts shot into the air, which seek their targets upon being fired. After looking down on the Earth from the Tenkai, Majin-Buu used this technique to kill every human on Earth.
Who can use: Majin-Buu

Kaioken
Taught to him by Kaio-sama, this is primarily a power-up move. When Gokuu uses this technique, he flares up and gains a large boost to his speed and power. Gokuu can also use multiplied power to his Kaioken. At first, he shouldn't have been able to go past 2 x Kaioken without seriously endangering himself, but eventually can increase the power of the Kaioken to around a 20 x Kaioken. Note that except in the TV series, Gokuu doesn't use his Kaioken as a Super Saiyajin.
Who can use: Goku

Kakusandan
This technique was used by Kurilin during the fight with Nappa and Vejiita, and is actually somewhat of an adaptation of an attack he used against Piccolo in the Tenkaichi-Budoukai. What he does is shoot a blast from each hand. Then he controls the blasts so that they merge and then directs it above the heads of his enemies. Thereupon he splits the blast again into many smaller ki bolts which rain down upon his enemies. A very effective technique which wiped out virtually all of the Saibaimen.
Who can use: Kurilin

Kakusanyudokodan
A potentially devastating maneuver, the user of this attack fires many ki bolts a la Renzoku Energy Dan around his opponent, surrounding them, then controls the bolts so they all shoot toward their target.
Who can use: Piccolo

Kamehameha
Quite possibly the most commonly used special technique in all of the DB/DBZ series, the Kamehameha is a technique created by Mutenroshi. It is a ki blast, which to start is charged up held behind the firer in cupped hands, then brought forward to release a large blast of energy. Gokuu later develops to ability to control the direction of the blast, shoot one from his feet, or with a single hand. Also, he later develops a Cho-Kamehameha with even more power than the standard fare. Goten can use it as well, but misprounounces it as "Kamekameha" when he uses it.
Who can use: Master roshi, Goku, Gohan, Yamcha, Kurilin, Tenshinhan, Cell, Cell Junior, Goten, Majin-Buu

The Generic Ki Blast
This technique is not particularly special, but is used so much in the Dragon Ball/Dragon Ball Z world that it at least needs to be mentioned. The Generic Ki Blast is shot from the hands, and explodes on impact for a lot of damage. This is by far the most used technique in the DB/DBZ series, next to standard punches and kicks.
Who can use: Practically everybody!

Kiai
This technique is used simply by yelling really loud; it disperses weaker ki attacks.
Who can use: Tenshinhan

Kiaiho
An invisible force attack that knocks one's opponent back. It can be shot either from an open palm or from the eyes.
Who can use: Goku, Freeza

Kienzan (distructo disc)
This is another attack that is used quite frequently during the second series. It is a flat, disc-shaped Ki blast, which can be used to slice through its target with deadly accuracy. The Kienzon can also be controlled by the firer.
Who can use: Krillin, Vegeta, Freeza, Cell, #18

Kikoho
This is Tenshinhan's strongest Ki blast. Tenshinhan puts the tips of his fingers of both hands together, forming kind of an "O" between his fingers and his thumbs. Then he shoots a very powerful Ki blast through the "O" at his opponent. While this attack is very powerful, it is also extremely damaging to Tenshinhan, and can kill him if he uses it too much. Later on Tenshinhan develops this technique to become the Shinkikoho, which is even more powerful.
Who can use: Tenshinhan, Cell, Cell Junior

Ki no Tsurugi
Literally "Sword of Ki." This is a ki beam that shoots out somewhat as an extention of the hand and can be swung and stabbed to cut or pierce enemies. The length of the beam can be controlled by the user.
Who can use: Vejeta

Kintoun
While not really an attack, Kintoun was used a lot by Goku in earlier battles to get him out of tight situations. Kintoun is a magic cloud created by Karin-sama. If you have a pure heart, you can ride the cloud and fly by controlling it mentally. If your heart is impure, you just fall right through it.
Who can use: Anyone with a pure heart

Koshoku
Coming from the planet of darkness, Yakon can "eat" light using this technique. In fact, he caused Gokuu to go from Super Saiya-jin to normal by "eating" his light. However, if he eats too much...
Who can use: Yakon

Kyodaika
This is a technique used by Piccolo during the 23rd Tenkaichi-Budoukai. With this technique Piccolo can grow his body to a huge size, making the range and strength of his blows much more effective. Of course, this makes him a larger target as well.
Who can use: Piccolo

Kyoken
This attack's name is kind of a pun; it technically is "Mad attack," but also can mean "Mad dog" when spelled with a different Kanji. Gokuu acts like a mad dog, barking and charging at his enemy to scare him, then jumps over him and kicks his surprised enemy from behind.
Who can use: Goku

Mafuba
This is a special Ki blast that is used to imprison demons. It is a swirling blast of energy shot at the intended demon. Once caught in the blast, the blast is directed into a jar, bottle, or other imprisonment container, thus imprisoning the said demon. However, if the container is opened, whoever is trapped inside will be freed. This technique is also extremely draining; it is very easy to kill oneself by overexertion using this attack. The originator of this technique is Mutaito, Mutenroshi's master.
Who can use: Mutaito, Master roshi, Tenshinhan, Kami-sama

Makankosappo (Special Beam Cannon or Drilling Attack)
One of Piccolo's most powerful techniques, this is a penatrating blast shot from two fingers. It is actually two blasts, one going straight ahead and the other coiling around the first for drilling power. This attack drills through everything it hits, and eventually blows up when it hits something big enough.
Who can use: Piccolo, Cell, Cell Junior

Makosen
This is a Ki blast that is used by Piccolo-Daimao. Piccolo gathers ki into both his arms, then fires a blast from each, one after the other. Not a particularly powerful attack when compared to some of the later moves, but it almost killed Gokuu once.
Who can use: Piccolo-Daimao

Masenko
This is Gohan's trademark energy blast, and is fairly powerful. Gohan powers up a blast over his head with both his hands, one palm behind the other, then brings his hands down in front of him to fire the blast. Gohan used this blast fairly often during the second series, especially during the Freeza saga.
Who can use: Son Gohan

Metamorphosis
This is not really an attack, but a body transformation. You think of something (or someone) you want to turn in to and then yell: "Transformation!!" (I don’t know how it is said in Chinese) and it with a lot of concentration you turn in to it. Depending on how hard you train for this technique is the time you’ll have the power for turning into the thing you want to.
Who can use: Oolong (only 5 minutes!), Puar

Mystic Attack
This is an attack first used by Piccolo during the Tenkaichi-Budoukai. Using the Namek ability to extend their arms, he extends his arm at his enemy from a distance, thus surprising them. Once Piccolo grabs his opponent, he draws him back for an attack like a punch or a kick.
Who can use: Any Namekian

Nyoibo
Not exactly a technique, but Gokuu uses his Nyoibo a lot in the first DB series. The Nyoibo is a magic staff that has the power to extend up to 380,000 kilometers upon command. At first Goku said "Bo yo, nobiro!" (Hey, staff, extend!) but later changed to "Nobiro, nyoibo!" (Extend, Nyoibo!), Goku stopped using it when it was needed to hold up either Korin's tower or Kami's lookout(i forgot which one).
Who can use: Probably anybody, but only Goku uses it

Papparapar
This is a magic spell that Babi-di can use to teleport people in his spaceship. Actually, he teleports the entire room, with the people in it, to another place.
Who can use: Babi-di

Pi
This isn't an energy blast or anything, but a stream of air that moves so quickly that it just bores through just about anything that it hits.
Who can use: Freeza, Cell

Rogafufuken
This attack is Yamcha's trademark technique; after preparing himself in a special stance, attacks with many "claw-like" punches and kicks, finishing off with a double-fisted "claw-punch." After training with Mutenroshi, Yamcha improves on this technique to become the Shin-(new)Rogafufuken.
Who can use: Yamcha

Rolling Satan Punch
Satan curls up into a ball, rolls along the ground, then punches his opponent. Being one of Satan's attacks, this one is pretty much useless in a "real" Dragon Ball/Dragon Ball Z fight.
Who can use: Mister Satan

Renzoku Energy Dan
While many characters can use this technique, the undisputed master of this technique is Vegeta. The user of this technique can shoot ki bolts continuously from his hands, resulting in somewhat of a "machine-gun ki blast" effect. While the indivual blasts are not particulary powerful, the effect of hundreds together can be devastating.
Who can use: Vegeta, Goku, Son Gohan, Piccolo.

Renzoku Shine, Shine Missile
This is Gotenks' adaptation of the Renzoku Energy Dan technique. Basically the same, but a whole lot more powerful.
Who can use: Gotenks

Racoom Kick
A charging knee blow used by Racoom of the Ginyu-tokusentai. Rather powerful.
Who can use: Racoom

Racoom Mahha Attack
The punch equivalent of his Kick, the Rikum Mahha Attack is a charging punch.
Who can use: Racoom

Saiko no Kogeki
Literally "Ultimate Attack," this is the Ki blast that Nappa shoots out of his mouth. Very powerful.
Who can use: Napa

Saimin no Jutsu
This is a technique that Jacky Chun can use to hypnotize someone and affect his or her mind. He used it agains Otoko-ookami during the 22nd Tenkaichi-Budoukai.
Who can use: Master roshi

Saruken
Much like Mutenroshi's "Suiken," this is primarily a "distract and avoid" technique; Gokuu acts like a monkey, using monkey-like attacks (scratching, bouncing, etc.) and taunting his opponent at the same time.
Who can use: Goku

Satan Special Ultra Super Megaton Punch
Mister Satan's "Ultimate" attack. Really just a normal punch. Mister Satan forgot the name of this attack almost as soon as he had made it. Used against #18 in the 37th Tenkaichi-Budoukai.
Who can use: Mister Satan

Sekikatsuba
This is one of Dabura's powerful attacks. Dabura's saliva will turn whatever it hits to stone, be it alive or not. The only way to reverse the petrification is to kill Darbura.
Who can use: Darbura

Shiyoken
This is a technique used by Tenshinhan to sprout an extra set of arms from his shoulders. Therefore he can both attack and block with all four arms, significantly increasing his attack and defense power.
Who can use: Tenshinhan

Shogekiha
This is almost exactly like the Kiaiho. It is an invisible blast shot from the eyes, hand, but is a little more versatile, and can be shot from any part of the body. Piccolo (Jr) can adapt this attack to radiate from his entire body.
Who can use: Piccolo, Kaiou-shin, Majin-Buu

Shunkanido
Not a fighting technique, but often used to gain a tactical advantage in a fight. The Shunkanido is a teleport. The user places two fingers on his forehead, searches for a ki he wants to go to, then when he finds it, can teleport there. It is not a technique that one can use to teleport wherever he pleases; there must be a person there to teleport to.
Who can use: Son Gokuu, Cell

Sokidan
This is a round energy ball shot from the palm of the hand. What is really special about this attack is that it is guided, probably the most easily guided energy attack in the first series. I think it was only used once, during the 23rd Tenkaichi-Budoukai.
Who can use: Yamcha

Spinning Cyclone
Gokuu only used this technique once during the first Tenkaichi-Budoukai in the series. He spins around at a very fast speed, at which point he turns into somewhat of a cyclone and knocks into his enemies. It didn't work too well because he got too dizzy. I guess that's why he never used it again.
Who can use: Goku

Suiken
This technique is used by Mutenroshi; he acts drunk and wobbles around. Thereby, he confuses his opponent, and hits them when they are off guard.
Who can use: Master roshi

Super Ghost Kamikaze Attack
One of Gotenks' strongest techniques, he spits out a ghost-like form closely resembling himself. The ghostlike form has a mind of its own, and when it hits anything, it explodes, severely damaging whatever is caught in the blast.
Who can use: Gotenks

Taiyoken (Solar Flare)
This technique is originally Tienshinhan's. The user puts his hands in front of his face, says "Solar Flare," and lights up very bright, so much that he blinds his opponent. This technique was used a lot througout Dragon Ball Z.
Who can use: Tenshinhan, Gokuu, Krillin, Cell

Tenkubekejiken
The user of this technique jumps high in the air, then on the way down, face forward with his arms in an "X" position, landing on his opponent with the arm "X." A very powerful technique when use on upon those without any special fighting powers.
Who can use: Namu

Time Freeze
This is an attack used by Guldo, the smallest member of the Ginyu-tokusentai. When he uses it, he freezes time for his opponents so that they are frozen in whatever position they were in. However, he needs to keep his attention on his victims in order to keep them frozen. Guldo also has the power to stop time completely, but for only a moment, and he can't do it for too many times without tiring himself out.
Who can use: Guldo

Tsuihidan
This is another technique used by Piccolo during the 23rd Tenkaichi-Budoukai. It is a ki blast, and it tracks its enemy much like Kurilin's Double Tsuihikidan.
Who can use: Piccolo

Udebunrikogeki
The user of this technique pulls a piece off of his body and controls it to attack his opponent in some way. Naturally, only Majin-Buu can use this technique.
Who can use: Majin-Buu

Yoikominminken
This was a technique used by Jacky Chun during the 21st Tenkaichi-Budoukai. It is a hypnosis technique used to put people into a deep sleep, by using a strange voice and hand motions.
Who can use: Master roshi

Yokaieki
This is a technique used by the Saibaimen. They split their head in two and shoot a stream of acid from it, which is very dangerous if it hits its target.
Who can use: Saibaimen

Zanzoken
Another technique created by Mutenroshi, with this technique, the user can move so fast he leaves an after-image, while attacking from another standpoint. Gokuu can also leave multiple images, I think the maximum he used was around 7 or 8 in Karin's tower. Later Mutenroshi learns to make large numbers of images as well.
Who can use: Goku, Master roshi, Krillin, Tenshinha
