Suggested by Destroyer A Polar Bear us a pretty tough animal who definitely won’t go down without a fight. It can stand up to very cold temperatures and has a good amount of physical power as well. That being said, I really don’t think that is going to faze Gigan. Keep in mind that Gigan is significantly larger than the Polar Bear and has more attack options. He can strike from afar with his lasers or get up close with the buzz saw. Either way that will be curtains for this animal. Gigan wins.
