Suggested by Destroyer Starfox has basic superhuman abilities like strength and speed so I won’t say that this match is completely one sided but at the end of the day he doesn’t really have any effective options to deal with Biollante. The kaiju can just squish him at any moment and there wouldn’t really be a whole lot that Starfox could do about it. He’s not fast enough to dodge and doesn’t have the durability to hang in there once the blows start flying. So in the end the only option here is to just take a big loss. He needs more firepower. Biollante wins.
