Professor Bender

Professor Bender appears to be the leader of the Ulbaks. He is involved with the creation of the composite spirit Ex-Machina, "a spirit that can beat all other spirits", but feels that it is not yet complete. His ultimate goal is to take over and control every spirit there is, as well merge them together into a more powerful spirit; Ex-machina was supposed to be the result of this. All he cares for is his research. While being the leader of the Ulbaks, he switched over to Tusk, as they want to use his technology to capture Amil Gaoul. When he used his ultimate system on Amil Gaoul, he found out that the system was not enough to work on Amil Gaoul. Amil Gaoul goes on destroying the central lab.

It is unknown if he has died when the island collapsed.
