Master Ikari

Before the War of the 7: Master Ikari was a giant woman, nearly 7 feet tall. Her and her clan made up a bulk of the frontline combat, directly engaging the Samurai who remained loyal to the Emperor. She was slain on the field of battle.
After the War of the 7: The current Master Ikari takes the "bear style" that the Ikari art is based on quite literally - the Ikari dojo is more of an animal den, and he proposes that practitioners file their teeth to make them more animalistic.
