I mean they have to lose right?

I think it’s safe to say if the Thunderbolts somehow manage to beat Sentry it would cause a lot of people to be mad, now i don’t want Thunderbolts to have a infinity war type of ending here, but i just don’t see them winning against this unless more characters come, maybe we get to see a look at the new avengers team in this movie. There’s no way a bunch of street level characters get to beat marvels version of superman, right?
