You know Picalo blew up the moon, right?
As for Vegeta... he destroys planets AND moons.
Goku, Gohan, and Trunks are all more powerful than Vegeta and Picalo.
Gotenks isnt even a person. He is a Trunks combined with a another character just as powerful as trunks into a single being.
Its a L fest for DC.
Martian Manhunter might get a win via telepathy if he could ambush picallo before the fight starts... and Tien could theoritcally lose if they fought in the ocean or something... but overall.
They sayiens destroy planets with hand waves.
Batman would outsmark Krillin amost immediately tho... He might trick him into telling him about the Dragon Balls. Thats about the only way DC gets the win.
The Vegeta video was DBZ filler and yes I know Piccolo blew the moon up.... with ENERGY. The point I'm making is that DBZ characters bust planets with their energy attacks, NOT with their physical abilities. Thus far, only Beerus has destroyed a planet with physical attacks. Nobody else in DBZ has done such yet.
