The Hoverbug is a slug that flies in velocity. In Protoform it can travel extremely fast whilst leaving a streak of blue light behind it. It has blue skin with wings that are purple with turquoise spots. When transformed, it looks like a pteranodon with no legs and a beak and can fly faster then while it is in protoform.
