Suggested by Anonymous Guyver has returned once more to claim another victim. Groot is a strong tree who has a lot of fans, but at the end of the day I don’t think there will be a whole lot that he can do against Guyver. Guyver’s got a cool suit of armor and a vast amount of strength. Groot isn’t particularly fast so he won’t be able to dodge any of the incoming attacks. Without any super durability to protect himself the fight is over for Groot before it has even begun. Guyver wins.
