Things Bizarro can do that Superman cannot. Like fight for fair-trade coffee, run for public office, eat green kryptonite and tell one Bizarro from another. I made it enjoyably (I hope) goofy rather than trying to get technical about a power comparison.
To celebrate here’s a useful anthropological look at customs of the Bizarro world (art by John Forte, I think)
and then this scene from the A. Bizarro miniseries (“When you clone Superman you get Bizarro; when you clone a regular guy you get … A. Bizarro!”) with art by Mark Bright.
