Ariel

A headstrong and feisty Omnicon, Ariel (Arcee) is eager to prove she's as capable a warrior as any other Cybertron (Autobot). She can manipulate and refine raw energon easily; her mastery of the Energon Bow is almost legendary. Unlike other Omnicons, there are not lots of her. She may one day assume the identity of Elita Seven. (Source: Transformers Wiki)
