 Gotenks

Here's a little section about Gotenks, his various forms... and a complete list of his attacks!
 

Name: Gotenks (Goten +Trunks)
Moves:

Moves in dark yellow indicate that they are in both the manga and the anime, while those in light yellow are only in the anime.

Rolling Thunder Punch: An ordinary punch.

Inoshishi (Wild Boar) Attack: Gotenks head buts the enemy.

Power Tackle: An ordinary attack.

Miracle Super Punch: Another ordinary punch.

Great Kick Special: (You guessed it) An ordinary kick.

Dynamite Kick: An ordinary kick.

Dynamite Kick Boomerang: A kick which causes an explosion where it connects.

Power Attack: An ordinary attack

Dangerous Machine Punch: An ordinary punch

Spiral Shooting Sobat: An ordinary attack

Burning Annido (Almond Tofu): Not known (he was knocked away before he did it, but one can assume it was just another ordinary attack)

Senju Kannon (Thousand-armed Goddess of Mercy) Punch: Gotenks punches very quickly so that it looks like he has lots of arms.

Daikaiten (Great Spinning) Kick: A spinning kick which unfortunately makes you very dizzy...

Magnum Sundae: A normal attack.

Ultra Missile Parfait: A normal attack.

Hyper Plasma Shortcake: A normal attack.

Super Kamikaze Ghost Attack: Kamekaze Ghost Attack is the most effective of Gotenks' attacks, and using it, he almost manages to defeat Majin Buu.

Gotenks spits out ghosts that look like him, each which have their own personalities and voices (and aren't all that bright...). They explode when they contact a surface... or as they soon found out, each other.

Gotenks uses this attack in the room of Spirit and Time against Buu, and in Movie 12. Majin Buu uses this attack after he absorbs Gotenks.

Galactic Donut Attack: Gotenks draws a rings of Ki and loops it over the enemy, crushing it. Once again, theoretically.

Renzoku (Continuous) Super Donuts: Gotenks shoots many 'Galactic Donut's at the enemy, encasing them into a ball.

Ultra Buu-Buu Volley Ball: (Also Ultra Buu-Buu Attack) Gotenks throws Buu around while wrapped up in the Renzoku Super Donuts.

Brain Crush Hammer: A normal attack.

Renzoku Shine Shine (Continous Die-Die) Missile: Gotenks throws a huge number of Ki-blasts at the enemy. This is also used in movie 13.

Balloon Flash Bomb: One of SSJ3 Gotenks' strange attacks.

Finish Flash: A normal blast

Super Balloon Bomber: A normal blast
 

Interesting: Gotenks is a fusion of Goten and Trunks both physically and mentally. He seems to have gotten his attitude from Trunks and appearence mostly from Goten. You kinda have to wonder where he got his attack names from though... In my mind, he doesn't seem much like Goten at all, as he lacks innocence, but perhaps Gotenks brings out some part of Goten that he doesn't usually show, like mischieviousness.

Forms: First attempt: Trunks forgot to point his fingers in the first fusion attempt... so the result was a super fat Gotenks!

Second attempt: Their fingers were a little apart, so Gotenks ended up as a sickly weakling.

Third attempt: The Gotenks we all know and love.

SSJ: Super Saiyajin Gotenks. At first they thought an SSJ fusion could only be formed by fusing while Super Saiyajin, but Goten and Trunks discovered while in the room of spirit and time that it could be done while fused. 

SSJ3: Gotenks managed to go SSJ3 while training in the Room of Spirit and Time. In order to follow Majin Buu out of the Room of Spirit and Time, Gotenks went Super Saiyajin Level 3 and yelled loudly enough to rip a hole in the dimentional wall.
