Gantu

His sudden attack on Stitch with such evil gusto was all due to the Friends once again trying to make a new client. For once, they actually manage to recruit Gantu after he got fired, and pointed him towards Dr. Hamsterviel afterwards. Unfortunately, his Face Heel Turn lowered his intelligence, making him from an intimidating presence of evil into something of a harmless joke. Thankfully, Gantu reformed from the dark side, and joined the High Council on probation after Hamsterviel's defeat.

In an alternate timeline where Stitch landed in Okinawa however, Gantu remains as an ally of Hamsterviel's.
