Oh! Well, I have several other preset pokemon characters and haven't really decided which one in particular.
I'm only considering three of the four others though, since the fourth is blatantly evil and thus would have no place in a school. |D
One is a young woman whose entire concept is basically "Cowgirl". That being said, her ideal team reflects that. (And is mostly normal pokemon such as Tauros, Bouffalant, and Miltank") Her "signature" pokemon would be a Bouffalant.
One is a young woman whose concept would be summed up as "Hipster". That being said, she has a very mixed type team and refuses to evolve her pokemon. She is a bit of an anti-hero because she would probably drive some (see: many) people crazy.
The last one is a bit eccentric compared to my other characters. She's a walking time paradox (See: From the past) and is a lot more flexible regarding her team than my other characters, as how hard she trains heavily depends on how others treat her and what she is taught.
I'm primarily looking at the first two, though the third is also an option. I have more detailed profiles of all these characters on my personal website, if you're interested in looking. >3<
