Aqan (DBTNG)

"Your the new Z-Fighters? Hmph, this will be cake."

Aqan is a reborn Buu created by the fusion of Baby and Buu in hell. He has power beyond anyone at the end of GT and the start of TNG. He has quite a few moves including Energy Stealing, a move that steals power and adds it to his own.

Moves
Cookie Cutter Beam, a beam that resembles the Kamehameha however red in color and the shape of a cylinder. It had the power to destroy a whole galaxy according to Aqan and used it to fatally injure Pan while using Tri-Form.

Hell Shuriken, a attack that is sharper then the Z-Sword and Aqan can direct anywhere he wants. It can hit a total of 6 times before it explodes. He used this to destroy East City and kill the Gatekeeper of Hell, allowing all the villans to escape. He also used it against Trunks but he dodged it quickly.

Multiple Hell Shuriken, a improved version of Hell Shuriken allowing up to 7 shurikens at once. He used this in effort to stop Gotenks but he caught them all.

Mosquito Swarm, a swarm of ki bullets almost impossible to dodge. He used this to destroy Venus in a show of his power and also injured Trunks. He did this also to Goten SS2 but Goten took all of the hits without being injured.

100% Power, he gets buff and his power increases 3x its normal. He did this against Gotenks and was evenly matched with him.

Tri-Form, a move that he stole from Tien when he drained his power. He used it against Pan and brutally each form used a Cookie Cutter Beam and each one hit Pan.

Full Power Cookie Cutter Beam, a move that clashed and was evenly matched with Gotenks's 10x Final Flash but Trunks, Pan, and Gohan supplied power to it and it overpowered this move, disentegrating Aqan in the process.

Power Level
Aqan had a power level of 1 trillon, equal to SSJ4 Gogeta. In his 100% form he has a power of 3 trillon.

Trivia
Aqan got his Mosquito Swarm from defeating Piccolo in hell and draining his power. He then knew how to use the Hellzone Grenade and made a few changes, for example the Hellzone grenade is yellow and the Mosquito Swarm is black.

Aqan is a fusion of Buu and Baby.
