Enough time has passed that we sort of forget about them... But worlds were rocked when Earth-2 Superman showed up.

Or how about crazy hypno Superman almost killing Batman?

Or how about Wonder Woman murking Max Lord

Or Batman's "Last time you inspired anyone was when you were dead" line...

Or Superboy Prime going apeshit insane


I'm fuzzy on the details, it was a while ago. But for the first half of Infinite Crisis, we were going completely bonkers over it. I remember that much. Too bad it didn't live up to its potential.
