Suggested by Destroyer Bouldergeist is a strong monster so lets not forget that. That being said, I don’t believe he will be doing a whole lot against the Baroness. She is fast and has a lot of energy weapons at the ready. Bouldergeist has no way of reliably landing hits on her while she can keep blasting away at him at her leisure. The hits will add up and ultimately Bouldergeist is going down here. There is just no escape. Baroness wins.
