Super Belly Bounce (スーパー腹バウンス), also called Super Belly Flop (スーパー腹フロップ), is the belly flop combo that is Aka's striking physical attack.
Immediately after Abo and Kado fuse to become Aka, they engage their opponents with a massive combo of powerful physical attacks. Aka propels himself upward and tightens his arms around himself before erupting outward and allowing his belly to bounce and flop his opponents upward.
This is the first strike Aka uses against Goten and Trunks as he surprises them with his deadly combination. This attack is followed by Aka's Super Grab and Drag and finally, his devastating Super Spin Toss finisher.
