He possesses great intelligence and knowledge about the universe and specializes in universal telepathic links. Even though he was already weaker than Vegeta before he taught Goku, King Kai is still a veritable library of skills, techniques and literally centuries of wisdom! Then again, we are still going to make him a jokester and gag character.

His voice I’m not looking much for, an impression of the funimation dub or ocean dub King Kai is fine by me. Just make sure you keep the goofy aspects to his voice, and then it’s fine.
