Which version of Infinite Man?
Tenebrous is an odd one. He really didn't do much on panel. His best showing, stalemating Galactus, is questionable because :
a) Galactus seems to have been hungry when it happened (he looked like he was about to devour a planet)
b) Tenebrous and Aegis ambushed him (Galactus wasn't expecting a fight).
Can Infinite Man at least stalemate a hungry Galactus that he took by surprise?
