Round 2: Death Stroke

Round 3: Parasite

Round 4: Metallo

Round 5: Brainiac

Might stop at Parasite or definitely gets stomped by Brainiac.

Hahaha! I've gotta admit I'm curious as to why no-one considers Metallo a threat. Though I do agree that Braniac and Parasite are much, much trickier to deal with.

Brainiac ftw.

Stops at Brainiac even with Kara's help
