Well, even though I'll probably lose, here's my entry.
and his team shot
(Just so you now, I used most of the sprites from BW, but I also used that Robo chu from HGSS and sorta tweaked it. Oh, and I used a Team Galactic Grunt for his body, and Red's legs for his lower body. I think I used the grunt's ears and Silver's head as Derick's head. But I made his backpack.)
Any way, this is Derick. Derick is a 17 year old boy who was getting bored of his training in the Darco region, so he and his Pal, Pikachu, set off to Milaborii, where he met these characters. Even though he was a D student in school, he has proven that you can't learn everything about Pokemon through books. He has trouble around girls, but once he gets to know them, he is a nice guy. He always keeps his Pikachu outside its ball, due to it being afraid of the dark.
Edit: I'll put in a little team background story:
1. Pikachu: Pikachu is Derick's best buddy, and ideally the strongest on his team. He has adopted so many of his mannerisms, it's hard to tell them apart.
2. Infernape: When transversing an ancient Native Miraborii civilazation (pretty much like the Aztec empire), Derick stumbled apon a group of the surviving Natives training with these Fire apes. Since He didn't want to be killed, Dercik offered to try to pass the right of passage, where a boy could befreind a Chimchar through hand the hand combat. He did, and was aloud to leave. Infernape was adventurous as a Chimchar, then just Curious as a Monferno. As an Infernape, he became a calm warrior who is always itching to fight.
3. Swampert: Derick encountered him as a Mudkip while transversing a swamp. Mudkip acted like a naive kid, always getting into trouble. As a Marshtomp, he stayed the same. As a Swampert, he is incredibally powerful, but he's still naiive about things. He considers Infernape to be his best friend.
4. Scizor: Scizor was Derick's first pokemon received in a trade. He traded a Drapion for it, and has never regreted it. Scizor is like a ninja, calm and cool, but strikes quickly and strongly.
5. Wargle (shiny): Wargle was captured in its present form. When Derick was traveling up the mountains, a predatory Wargle appeared and tried to eat Derick's Pikachu. However, just as Pikachu was about to be swallowed, he shocked him out of the sky. As it turned out, the shiny Wargle were more dominant in the Milaborii region than normal ones. However, this has not tainted his spirit, as Wargle is a gutsy fighter who does not seem to know when to quit.
6. Sazando: Sazando was captured as a Monozu without a care in the world. Back then, he would listen to everything Derick said, that is, until he evolved into Jiheddo, then things turned for the worst. After his final evolution, Sazando was nearly out of control. He goes insane when the moon is full.
