The sentry? the crying baby? the crazy jerk? vs Superman ?!

Superman for the win!!

im picking superman, because the Sentry would just let superman beat him to a pulp while he whined about not wanting to hurt anyone. Also, if he did fight, the sentry is supposed to harness radiation similiar to what comes from the sun, the sun makes superman more powerful.

Superman would own him.

Well Sentry can control moleculs.
