Suggested by Destroyer Bulma is a genius who can invent just about anything, but combat isn’t really her specialty. She doesn’t have any means to really attack Biollante with. She can maybe dodge some of the strikes without an issue and land some good counter attacks to deal 0 damage but at the end of the day it would just buy her time at best. She isn’t ready to take on a Kaiju level opponent, not yet at least. Biollante wins.
