Houndoom, all Teachers are just NPC's volunteered for use within the school. Your main char is a student.

And on that note i wish to volunteer one....

Name/Codename: Chloe Reynolds/Blueprint
Sex: Female
Age: 24
Class(es) Taught: Biology/Physics/Natural Sciences. Power awareness and function (Basic to Advanced)
Personality/Description: She's in the same vein as most female Scientists in the Marvel universe. A Shy unnassuming bookworm type that also happens to be an unexpected, and sometimes unrecognisable stunner when she lets her hair down. Shes slim, around 5ft 8 and has long red hair usually tied back in a loose ponytail. She wears glasses but only for reading and is most often seen in a baggy labcoat. Personality wise shes friendly and kind but mostly shy. Preffering to bury her nose in a book or tinker with some project she has on the go.
Powers: She has the ability to figure out how something works just by the merest of assesments be it something simple such as an engine or clockwork mechanism right up to Nuclear engines and experimental machines.
She has a sense for what will and wont work, able to look at a schematic for a design and know for certain if it will work and if not, why not as well as a solution of how to make it work, with 100% accuracy.
It is in this way she assists the students as her power also applies to biological functions. She can figure out exactly how a students power works simply by watching it in action and help them accheive their potential much faster.
Other: Her power has led her to be a little bit of a perfectionist. She gets annoyed by the smallest things, like a clock ticking 5/100'ths of a second too fast for example, annoyed at how much time they would be losing over a day because of it.
