Who should be th villain in Vol. 3

I just assumed it'd be Adam Warlock (for obvious reasons) but I've always wanted to see Annihilus in live action, thought he always looked cool.

 

I am hoping High Evolutionary will be reveled as the scientist who created Rocket - remains to be see if that makes him a villain or not...

 

How long does it take to grow someone in those pods?

We left the guardians 4 years ago (second film meant to be shortly after the first?).
Adam's not in infinity .
So where do we go? He emerges chases them, then they face a baddie and team up?
Magus might be a bit quick.

 

Warlock/Magus could be the villain or maybe somebody else. The High Evolutionary would make sense too.

 

I think its both of them. High Evolutionary to solve Rockets backgroundstory and Warlock, because he was already teased in both movies after credits
