Story

A member of the Frieza Force, Kado had the good fortune to be on a different planet when Frieza destroyed Planet Namek, and thus escaped destruction.

At the time he was said to be of roughly comparable strength to the Ginyu Force.
In the present day, he and his older brother Abo attack the planet where Vegeta’s younger brother Tarble lives, and when Tarble flees to Earth, the duo give pursuit.

Angry, they split into multiple clones which run roughshod over the two boys.
However, thanks to Gohan’s advice, the kids are able to see through the technique!

With no other options left, Kado combines with Abo to transform into Aka!
Alas for them, they aren’t the only ones who can combine, as Trunks and Goten fuse into Gotenks!!
After being pressured, Aka whips out one of his special super destructive energy attacks, the Wahaha Wave! Gotenks is able to deflect it, but the blast then ricochets off towards Bulma and the others. Things seem bad, but Piccolo comes to the boys' aid and splits it in two with a timely Makankosappo: Special Beam Cannon.

Aka then uses the even stronger Super Wahaha Wave to lay waste to Mr. Satan’s hotel.
Not stopping there, he then readies an even more deadly and massive Full Power Wahaha Wave but Goku pops the energy ball with a Kamehameha and then and knocks out Aka with a single mighty punch.
