Kuma is one of the most extraordinary Tekken characters. Tekken 7's gaming community, probably, is considered about Kuma, that he's a bit weakened compared to other fighters. However, if you know how to play for Kuma, this opinion can be changed fast. He has probably the best whiff punishers in the game, powerful wall damage, and really good traps.
We can say that Kuma is pretty an underrated character. He has a lot of tools for winning, but it's hard enough to learn about them. At the same time, he is lacking fighting tools in some areas, but he is justified by the fact that Kuma is a big and very love bear.
He is viable and able to compete against every character in the game in good hands. It requires attentiveness and thoughtfulness of actions to win. He is also in love with Panda. Probably not mutual.
Kuma's playstyle - Bait and whiff punish.
