GACKT! / Burp Beam (LV1)
Essentially a super version of the BLORK!, Buu charges up and then shoots out a multi-hitting energy beam from his mouth. It starts out being launched diagonally into the air and then Buu angles it downward until it's horizontal. The beam's damage is based on distance; doing more damage the closer the enemy is to the orgin of it (closer to Buu). Hold the Punch button you used to activate the move to charge it up. This leaves you completely vulnerable but firing a charged version does more hits and damage.
Vice Shot (LV1)
Buu charges up an energy ball, then teleports to one of a variety of positions around the opponent (choose with the directions listed above, or neutral to make him re-appear directly in front of them), then releases an electric sphere towards the opponent, knocking them away with the last hit. A very fun move!
Heavy Rain (LV1)
A tamed-down version of Buu's Human Extinction attack, Buu fires off a volley of energy blasts straight into the air (these can hit the opponent). After a short while, these blasts come raining down on top of the opponent, vaguely homing in on their position.
Madman's Ball (LV1)
Buu's going bonkers! An on-acid version of his Maniac Ball, Buu bounces around the stage on an extremely high speed, knocking the enemy silly. Wheee!
Pain Train (LV1)
Buu powers up, emitting a pink glow, then charges forward in an unstoppable trot! The enemy will get knocked down upon the first contact, then get trampled on for additional hits and damage until Buu crashes head-first into the wall, knocking him back. This means the move will be most effective the longer the stretch of stage ahead of you is. The Pain Train has full of armor and is unblockable.
Angry Vice Shot (LV2)
After teleporting to his desired location and firing his first Vice Shot, Buu will automatically charge up and then release another one. For this second shot before launching it you'll again have the option to re-appear at a position of your choosing. Twice the fun, twice the damage!
Flesh Prison (LV2)
Ground-to-air or air-to-air tool. Buu shapes himself into a kite and flies forward. If he touches the opponent he wraps himself around them. This works as a throw, so it's unblockable. After struggling to get out of this fleshy prison, the opponent is launched into the air after Buu blows himself up.
It'll grab standing and aerial opponents. The opponent can evade a raw attempt at this attack by keeping a cool head and crouching.
Kill You (LV3)
Time to get nasty! Buu stuns the opponent with a mighty shout. Then he shoots into the air whilst forming into a stream of goo before returning back down, aimed directly at the opponent's head. He then violenty enters their body through their mouth! While inside, he punches, kicks and knocks them around! That's got to hurt the intestines. When he's bored, he exits the opponent's body and reforms.
