Udyr in a fighter?

Udyr

Passive Effect: When Udyr switches stances, he gains a bonus effect on the first attack he lands on the opponent (blocked or hit), depending on stance. He also gains persistent effects when in a stance. Udyr cannot change stances 30 frames after activating a stance, and he cannot switch into the stance he is currently using. (eg: You can switch from Turtle to Bear, but you cannot switch from Tiger to Tiger.)

Moves (WIP)
22A/B/C/D: Stance Switch
A: Tiger. Switching into this stance grants increased walk speed and turns Udyr's dash into a run. The first hit landed while in this stance can be dash- or jump-cancelled, and on hit, applies an 80% multiplicative scaling to that move, regardless of current proration in the combo.
B: Turtle. Switching into this stance grants super-armor that ignores one hit on certain moves at the cost of not being able to chain normals and turning Udyr's jump into a short hop. The first attack landed in this stance heals Udyr for 10% of the base damage on hit, 4% on block and 15% on counter-hit.
C: Bear. Switching into this stance makes Udyr's moves do 5% more damage and turns Udyr's jump into a double or super jump. The first attack landed in this stance has increased hitstun and, depending on the move, has an additional hitstun effect, such as a stagger or a wallstick.
D: Phoenix. Switching into this stance adds extra range to Udyr's normals and gives him an airdash. (?)The first attack landed in this stance inflicts a burn that does up to 300 damage over 180 frames (3 seconds). This burn can bring the opponent's HP down to 1, but cannot outright kill them, and can be removed by hitting Udyr.
