While featuring mainly powerful and "animalistic" claw sweeps and brute strikes, this fighting style is suited for highly intelligent animals such as Kuma and Panda and allows them to use their primal instincts for skillful maneuvers that normal animals don't use, such as kicks, sweeps and combos. This fighting style also features some of Heihachi's favourite personal techniques, such as the Demon Uppercut and the Stonehead. Farts and other bizarre moves are also included.
