Honestly, I don't think this is a sweep. Andromache has no feats, and Destine was introduced and killed in the same issue before showcasing her stuff. She returned later but still did basically nothing but get beat up. I'd switch Andromache out for Olympia. At least Olympia stalemated Zealot briefly.
That said, Sarin could possibly make up for all of that. That girl's equipment makes her hard to handle. She effortlessly beat Zealot to within an inch of her life, has multi-city block level explosives, and stats seemingly on par with Agent Orange.
I'm not sure anyone on the Marvel side can take on Sarin. With her equipment, she might be able to fight several at once......and kill her remaining teammates afterwards.
