Kuma (and Panda, often referred to as bears) is the closest thing Tekken has to a joke character. His movement is exceptionally bad to the point where learning to sidestep or backdash cancel properly is almost unnecessary. ---> Really unnecessary indeed.
To somewhat make up for this he has a lot of moves with great range and tracking, which almost creates a symmetry where the opponent doesn't need to move either.
He has a wide variety of party moves to murder the unaware: a hard to see Snake Edge, powerful string extensions (e.g. second hit of b,db,d,df+2,2 is a low launcher), moves with weird recovery or that recover grounded, and unique grounded attacks. However, as far as cheese is concerned these rarely go beyond basic knowledge checks.
Strengths
Standing hurtbox can make lows whiff when they normally wouldn't (legs are further back than usual)
