Suggested by iKnowledge Dr. Polaris and Kat both have impressive abilities but Kat has mastered her techniques to a whole other level. Polaris has magnetism which he can use to repel fighters or bring them in close but he doesn’t have a lot of close combat options. Meanwhile Kat can control her personal gravity and emit it while landing quick hits at a rapid pace. Polaris would very quickly be overwhelmed in battle and would not last long here. Kat (Gravity Rush) wins.
