I raised him thinking he'd start with 100 combat power, but...

There's this hero, I think they called him 'Hero Knight', looks like a knight and all. Started with 100 combat power, so I thought he was super strong, but nope. I'm still only level 55, but everyone else's heroes are hitting 25000-30000, while that knight is stuck at a measly 20000... I mean, he's better than the Hydra soldiers, but this is just too much.
