A 15-year old female exchange student from Japan, though you wouldn't know it from talking with her since she's so fully absorbed American pop culture. MIKO is a free spirit who dresses in exuberant punk clothes, and doesn't care what people think or say about her eccentric appearance. It's only natural that the one with the interest in 'speed metal' would instantly bond with the AUTOBOT who's the most 'heavy metal': BULKHEAD. Miko is a thrill seeker and pretty fearless, though not always in a good way; she often gets the Teens into dangerous situations and improvises crazy solutions that only complicate matters. She's always well-meaning, though; and no matter what, she always has JACK'S and RAF'S backs.
