Sashi Kobayashi is one of the best friends of Penn Zero, and her specs can give the Part time Heroes the mission objectives. Sashi is also one of the only female Dimension Warriors. Not only that, she is also their leader. She was probably based on Mandy and Gretchen. Sashi is a true warrior, and can kick butt like Mandy and Gretchen. She helped save the universe from Rippen (Who is also the art teacher at her school) (and his number two Larry (The principal)) numerous times.
