Note: Without using Kryptonite or blocking out the Earth's
Yellow Sun in any ways possible!
My list:
1)All the Major Characters in Dragon Ball(Including most villians
)
2)Ultraman(Only in Space, where he is not bounded by the 3-minute
time limit weakness on Earth )
3)Sun Goku from Sayuki Reloaded
Anymore, people?
I can only think of these 3 guys!
