The problem with the Runaways as ya inspiration is that all of their powers are fairly complex and well above basic. A closer idea ta what ya're saying is Avengers Academy. Ah'm interested. Here's mah character sheet.

Race: Native American (unknown which tribe of origin)
Education: Little Rodeo has not had any formal education, but has learned a great many things by just hanging around his adoptive parent for so long.
Description: Little Rodeo wears a plain T-shirt and jeans. He looks like a skinny, but otherwise normal teenager.
Abilities: Terrakinesis; the ability to manipulate any naturally occurring geologic entity.
