Daiku- a human engineer and friend of Akari.
Megatron- Tyranic Lord of the Decepticons, and once Prime's brother. His alternate mode is a strange, disfigured jet which can convert to tank and cannon modes.
Bumblebee- A short and annoying little guy, yet also one of the Autobot's most trusted scouts. He has many insecurities wjth himself- is he too short? Is he weak? Will he ever pick up a femme bot? He does not know the answer to any of these, ahynd takes out his frustration by kicking Decepticon tail pipe. He transforms into a Volkswagen Beetle, and runs on electricity.
Soundwave- The eyes and ears of Megatron. He has many shapes, and none of them can speak properly- he had his voice box destroyed in a laser fight, and has had it replaced by his own design of voice-synthisizer, which can record, create sonic attacks and copy voices, but causes him to speak oddly, and think ultralogically.
Transforms into a Blue and Orange Kia Sole, and can eject the interior of his head to become a boombox version of himself. Manipulates Minicons. Totally superior.
