This is edited to fit a bit more than mostly attacks. I try to strategies myself after doing many competitive battles with my friends in playing with Pokemon X. So I am being a bit smarter in move sets and consider some of it's second ability.
Character Profile
Name: Hitomi Luka
Age: 15 (I'm gonna make everyone 15 considering Ash/Satoshi was supposed to be at least 20 by now and somehow he is still 10. Brock/Takeshi on the other hand is gonna be a year older so he is 16 which I swear is supposed to be what at least 25 or something).
Looks: Slightly light tan skin. Black hair, waist length and is normally tied in a low ponytail. Bangs sweep to the right of her eyes. Her eye color is bubble gum pink. She wears a green t-shirt saying in yellow "Graceful yet Powerful," and a red jacket over it unzipped. She wears tan cargo pants. Then her sneakers are light blue with white streaks. Her purple shoulder backpack holds all her necessary items. She wears a small belt that holds her 6 Pokémon. A bracelet on her wrist with charms of her 6 main Pokemon which is Eevee, Salamence, Umbreon, Mismagius, Riolu and Metagross.
Personality: can be both kind and rude, quiet at times when around people she doesn't know but really loud when she is with her friends. Sometimes she can be really animating. When it comes to battling she is willing to show her loud side.
Occupation: Frontier Brain (yeah she's a Frontier Brain in the Battle Manor at the Hoenn Battle Frontier. I'll explain her background about this later) she is just taking a break and traveling in her home region Sinnoh
Pokémon (She has two of each regarding for the Battle Frontier rules in the game which is level 50 or lower battle and open battle which ranges from levels 1-100 depending on your Pokémon's level, I think. But if it's the anime they never show what level Pokémon's are so I assume things like how I assume Ash's Pikachu is... what... level 100 by now? I mean like really?! You know how long Ash has Pikachu for?! Almost 15 years and it some how gets downgraded to the lowest level!):

I am using the Japanese names for the people except for those who might have ridiculous names in the Japanese version that I, no joke, think is really long or just plain stupid. I am using Gen 5 move set and I might add some Gen 6 in there somewhere along with its mega stones even though the Sinnoh series didn't have it yet. Hitomi will have a new set of Pokemon of course and these are the ones she uses when in the Battle Manor and will switch off from Eevee to one of them so each of them will have a chance to shine along with the new team.
