Artist Leonardo
Before battle: "If I win, I will paint a picture of your humiliated look."
Defeat: "...Aw. I suppose I'll have to paint a self-portrait instead."
After battle: "Do you have a mirror I can borrow."

"I used to be a trainer like you, until I took an Arrokuda to the knee."

"My fellow classmates picked on me because I don't have a cool Pokémon."
"Well, a pen pal of mine from the Kanto region sent me a Charmander."
"If it fully-evolves into Charizard, then they'll take back everything they've said about me."

(After Badge 2) "My Charmander evolved! I am one step closer to becoming one of the cool kids!"

(After Badge 5) "Well that's great. I finally got a Charizard and I still get made fun of. The cool kids said that Charizard is for normies."
