King Kaioh
King Kaioh is the owner of the Training grounds on the tiny planet just off Snake Road. King Kaioh's planet is more then 1 G of gravity. So you are training just standing up. He has two partners...or trainers, Bubbles the monkey, and Gregory the grasshopper like insect. King Kaioh taught Goku the Spirit Bomb and the Kao-kin attack. King Kaioh is a funny being. He training is cathcing Bubbles, hitting Gregory with a mallet, and making him laugh with a good joke. What a trainer!
