Sedoru

The Chief of the Sixth Branch of the Bishokukai and the Food Procurement Team, Sedoru fought against Sunny inside the Regal Mammoth. He uses the skulls of animals as shoulder pads and has some kind of interest with eyeballs since he wears a necklace of them, which he collects from the animals he kills and throws them away when they rot and stop moving. He is evidently weaker than the other Branch Chiefs of the Bishokukai, as Joejoe mentions that he cannot utilize the GT Robo to its fullest potential.
