Yeah I know but after Onslaught was inverted/defeated, how is Red Skull's body alive? His head got splattered like grapefruit.
Don't OFFICIALLY know, but I'll take a crack at it...
In the original story, When Onslaught first appeared, Xavier's body was still being stored inside of Onslaught's shell, in perfect condition, and Thor actually had to rip Xavier out. Nate Grey and Franklin Richards were also both housed inside of his shell as well, in perfect condition.
I don't suppose its out of the question to believe Red Onslaught can do the same with his own body

Mannnn, that shyt sounds AMAZING. I can't fukkin wait. 


LOL, I low key felt that run was a hidden gem. They both were used to being the leader and decision maker and neither could or would adjust to each other's styles. Cap would give commands and Reed would just do his own thing, but it wound up being justified because Reed always ended up saving the day. Cap was a furious hater here, it was justified but still hilarious
