Sensei Kora is actually a former combat trainer. He works with Harri Neale from time to time and still teaches elemental and energy combat techniques, in other words, how a pokemon can apply his/her special abilities in hand-to-hand combat, but otherwise, he just brews tea and arranges the company zen garden. He is fiercely non-sexual on the surface due to his wise ways, but if you can get him to face off with you- it will end with you underneath him.
