Geetz is a Servitor Unit. His duty is to act as Mistress Sera's assistant and guardian if necessary, and he will do anything to protect her. He has the ability to transform into a golden, flying reaverbot.

Sealed away along with Sera on Forbidden Island, he does a bit of deceptive talking when they are freed and taken aboard the Sulpher Bottom, in an attempt to excite Von Bleucher into finding the Four Keys that he and Sera need for themselves.

Geetz's role is important and yet very small, as he hardly has any appearances. He follows the path of the System and, like Sera, is Trigger's enemy.
