OWAW Sentry
This is Sentry at his best (minus Death Sentry) taking Superman place during OWAW. Everything that happened or everything Superman accomplished during OWAW Sentry is also put in that same situation. If Superman has an amp, Sentry receive an extra dose of Serum (if it has anything to do with the sun)...3 doses for the planet pushing or he would receive whatever amp Superman received during the story.
Can he succeed or where would he end up failing?
