@KaKaShI1531244 I think Saitama has not infinite power but potential, means the longer a fight the more he might overpower an opponent. One might need full power and their strongest attack from the start to win. Or not since Saitama is a joke character who always wins.
@OmoAlade007 It needs at least 500 or more individuals to maintain genetic variation without ending in an inbreed situation but only 50 pureblood Viltrumites survived. Therefore they had no other choice.
Kradd couldn't heal after being hit by the Infinity Ray
The shot looked like it missed his heart and brain, but he still couldn't regenerate
I thought Viltrumites could recover from anything as long as their heart and brain are okay???
