Well, I guess i'll give it a go.
trainer name: Sumanth or B.R.S., if you prefer.
trainer type: Expert, but a very young and youthful one. Try to make me a very strong bad character who the hero loses to in the beginning or something like that but reclaims himself after some happenings and joins the hero.
Favorite type: Psychic, Fairy, Grass, Ice, Steel
Theme: The pokemons might not look strong but are real strong like an azumarill, gardevoir, vanilluxe,etc.
Ace Pokemon: Mega Venusaur, Escavalier(holding Occa Berry) (with Drill Run, Megahorn, Iron Head). EV trained equally tanky and offensive if an important character.
Character traits or personality: Usually found at the end of a big forest or after a big long route between cities. Very knowledgeable and experienced but harsh in the beginning, heroic at the end.
Sprite:
I know this is from Naruto, an anime I like but this would be great.
Make me one of the bad guys who turn good if there is such a thing in your game. It would be really great of you.
