This is amazing!
I really like Nidoking or as you call him, the big purple dude. He looks like if he were to be in battle mode he'd be the scariest son of a bitch on the screen.
Charizard is definitely a badass here too. He's got battle scars and his neck is super buff. I do think the fire on his tail should have been a bit more intense, but we'll just pretend that he's holding back for the sake of his trainer.
Gyarados really makes me laugh because he doesn't look so much angry as he does simply not impressed with anything.
Everyone else was done really good as well. This guy has a pretty kickass team. It would be neat to see a submission of him as a younger trainer with all of the base pokemon of these evolutions.
