DC 7 in the Marvel U

7 Dc heroes r sent 2 the Marvel U.. There they take the place of the Mighty Avengers.. The DC 7 start from the start of the Avengers history, from the start of the teams formation..

Can they succeed in protecting Earth or do they fail? If they fail, when? 2 whom? Why?

The Mighty Avengers:
Batman (Bruce)
Cap.Marvel (Billy)
G.L Allen Scott
Wonder Woman
Manhunter
Flash (Barry)
Cyborg

They would have many rough patches with Kang, Ultron, and Korvak but would be soundly defeated by Thanos during the Infinity Gauntlet.

I think they do okay. Cap Marvel is bounds above any of the Avengers roster, he should be able to make up the slack that they lose on some others.
