If you've played Dragonball Z: Super Sonic Warriors 2 Secrets, there's a 99% chance you know about most of the team attacks. But did you know there are SECRET team attacks? When the game was made there were special teams you could use that it doesn't tell you. And here's the list of them

Secrets by Mozeta
Goku (SSJ), Adult Gohan, and Gotenks - Does Kamehameha Wave simillar to what they used on broly.

Goku (normal), SSJ2 Gohan, and Bardock - Uhh ... I forget. It's the Family Kamehameha then Bardock does something.

Perfect Cell, Super Buu, Frieza (normal) - Attack similar to Ultimate Evil

Trunks (SSJ), Vegeta (SSJ), Gotenks (SSJ3) - Similar to Family Kamehameha only with Trunks, Vegeta, and Kid Trunks

Goku (normal), Vegeta (normal), Piccolo - All fire a beam at opponent.

Well, I hope this helps. Have fun!
