Best friends forever until death do they un-fuse, Gotenks is here and he’s everything we hoped he would be. This monster of a mash-up between Goten and Trunks is a Strike and Blast Damage powerhouse with an exceptionally high Health stat to boot.

His Galactic Donut Special Move deals major Damage and Stuns the Enemy Fighter.

Gotenks also gets an Ultimate Move called Super Ghost Kamikaze Attack, which cannot be dodged because it's coming at the Enemy from all sides!

More than likely he will be a Super Saiyan Hybrid Saiyan to match up with his officially recommended Teammates:

The Gotenks section also mentions a Unique Ability of some sort which appears to require certain conditions to activate. The two big theories around GamePress headquarters are that:

this Unique activates after a certain number of timer counts have passed (which would be similar but opposite of SP SSJ Kid Goten GRN and SP SSJ Kid Trunks YEL’s shared theme of having Uniques that only work for the first 30 timer counts of a Match. The Unique Ability only activates after another Ability or Move is used--and we know from his promotional teaser image that Gotenks DOES have a Fusion based Ability or Move.

Either way, this is an Offense Fighter, the likes of which we’ve never seen before.
