Suggested by Sonic Victor is a nice guy and he does have a Pikachu so we shouldn’t count him out right off the jump, but he’s not ready to beat a full fledged professor like this. Oak has had his share of Pokemon over the years and was even going to make it to the tournament finals in the Pokemon Adventures manga. Victor’s really got no chance against someone like this and will need to return in the Pokemon anime to even think of making a comeback. Professor Oak wins.
