He's uberly sexy, and I would do anything to get into his pants.
He's got a huge Stone fetish, and appeared in a single episode in the anime (Lance stole his spotlight during the Team Magma & Aqua thingy), but has a major part in the Pokemon Special manga, during the Ruby & Sapphire arc.
Can you believe he actually spent ages in Dewford Cave (in the anime) looking for a FIRE STONE? And Fire Stones can be BOUGHT in Kanto! You're not exactly that bright, are you, Steven? And he can't say he couldn't afford the fire stone, he's filthy rich.
Oh, and in Pokemon Platinum, he used to own the villa that you (the player) get in the Resort Area. Isn't that nice?
He's commonly paired up with:
Scott (PedoStalkerShipping - I'm not lying, that's the name)
...and just about any other character and/or Pokemon in the canon.
Fangirl 2: I agree, Steven is uberly sexy. But I'm a HoennChampionShipper
Fangirl 1: NUHUHHHHH, ORIGINSHIPPY KYAAAAAAA
Fangirl 2: k, that's nice
