LOL @ DBZ fans. SSJ4 Goku megaton level is 21 septillion megatons. That's 0.212% of a supernova. Superman shugged off 15 Supernovae to the face. 150 octillion megatons. Enough power to kill the solar system 15 times. Hell, I find it funny the my youngest hybrid character ( age 6 ) could destroy the entire DBZ universe. 21 septillion megatons?! Pathetic! Finally after 18 years I know Goku's megaton energy level. Goku needs at least 12 decillion megatons to even be a match for my hybrids or even superman.
