I don't see so much BFR being an issue but the the Battlefield itself being removed.😂
I don't see either parties putting either down cept Angir. Angir appeared to be the most troubled and vulnerable.
But all 3 at the same time! Considering Thanos was constantly growing in the Thanos Imperative and the items it took just to KO him temporarily during his growth makes this guess work. The truth is we don't know how powerful Thanos is presently. People need to give it a rest until he comes back and has some real fights.
Thanos Imperative was an upgrade that never reached full fruition.
