I was rather annoyed by Bede, as he was definitely the most villainous rival out of your three.
He comes out of nowhere, and claims superiority. He’s endorsed by Chairman Rose, and thinks he all he’s all high-and-mighty.
And it is Chairman Rose who disowns him when he gets too crazy.
Opals selects him as the next gym leader, only because she likes his clothes. That was rather strange.
That doesn’t stop him from challenging you again in a de facto tournament match.
He did get to see me become Pokemon champion. I hope he enjoyed it, haha.
