Koreena is a feline alien with blue hair, white fur with blue tiger stripes and red eyes. She was a former student of Spindly Tam Kanushu at the same time that Betty was in training. However, Koreena was a snob who was lazy, idled her time away playing video games instead of focusing on her training, and cheated on all her tests by copying off Betty during a test. She refuses to acknowledge her behavior, insisting that Betty stole her position as a Galactic Guardian by charming her way into being Spindly Tam's favorite student. She is, nevertheless, an expert in robotics.
