As lame as these dudes all are some of them do actually have connections to Sunspot's New Avengers team members.
jeezus, Marvel. how obscure can you get.
I would give a rundown...
but really....
who cares?
Power Skrull (the green one) was an attempt by the Skrulls to create another Super-Skrull; he has fought the Fantastic Four a couple times and is there as a adversary to Hulkling who is a Skrull prince
Asti the All Seeing (the floating mask thing) is a minion of Dormammu and has fought Dr. Strange a bunch of times as well as having gone after Scarlet Witch before which matches it with Wiccan
Angar the Screamer (the hippie looking dude) is Songbird's former partner and lover when she was a villain and went under the name Screaming Mimi
Vermin (the furry dude hanging on the wires) is most likely there to face off against Squirrle Girl; the two characters don't have a prior history but Vermin does have the ability to control small animals like rats and squirrels so I guess that is what the writer will be going for when the characters fight
Skar (the guy with no face) is ridiculously obscure and has appeared in a shytty 90s cosmic miniseries as a space mercenary and before that was an assassin in the Killraven comic book from the 70s; I have no clue who he is supposed to particularly be an enemy for because he has no past history with anyone on the New Avengers team... he does shoot energy beams out of that hole in his face though
That's it. Thanks breh
