Judging from Onslaught Reborn #2, the most lucrative business in the Heroes Reborn Universe must be chiropractic neck realignment.

Let's count how many times someone gets punched and his head goes flying backwards in a manner that would strain his neck at best and snap his spine at worst:

One

Two

Three

Four

Five

(Note that Captain America's neck still hasn't recovered and is about four inches longer than it should be, allowing him to his head parallel to his shoulders like that)

Six

Seven

Eight


Oh, and something seemed to be missing from this panel. I finally realized, it needed a sound effect.
