I had no clue tbh I also hadn’t really thought about it

Val, Thunderbolt Ross and his team of Dark Avengers, or the Government in general. There was a time when I thought that a version of Tony Masters was going to show up as Antonia's Rival.

Ross, but I didn't care about the film when it first came out

Val

Honesty, I'll still think that Val is going to be revealed as the true Big Bad of this film and is using the Void/Sentry as her personal Weapon or something. I'll just don't trusted her character anymore after What she did in Black Widow/Hawkeye lol.

Most likely, Val will be the main one, and Bob will be secondary.

A random villain from the past who would have been brought back
