Accepted. Keep in mind if Spawn is more powerful than the power limit, you can have him if you explain how he can fit in with the other characters without stealing the show.

Spawn’s power level fluctuates depending on a few factors. I’ll probably start him early off in his career as a Hellspawn when he was just an Antohero in an alley before he went on to the fighting God and Satan arcs he had. 
Spawn does have a history of getting mad over powered, but he also has a history of giving up said powers. 
Given the idea of reincarnation, this Spawn would have given up most of his powers when he died, and would be starting again.
