Mimic is regretfully a regular character now, and on the team (the first non-mutant to join), so I guess it makes sense to have him fight Super-Adaptoid, the dude who has all the Avengers’ powers.
It makes sense, but … It still can’t redeem this terrible, terrible run of comics.
And it gets worse in #30, when they fight Merlin.
