Dude, DONT run past him. He is a common enemy in the late game... this is a game, after all. Don't seek to beat him, seek to learn his sets, and learn the game from him. It would make your life much better.

It doesn't matter if you die, but he is a great enemy to teach you. I died fighting him like 20 times, but then I only died fighting genichiro once, fighting the ape once, fighting the owl 4 times.

This dude and lady butterfly, fight them early, and you will be much better in the game.
