Theodore is a Skrall who works for the Invisory Commission. He likes wearing shades.
Along with Fero (SMU), Branar (SMU), and Harold, he was chosen by Axel F to participate in the attempt to capture the 'war criminal' D-Klak. He was part of Branar's team, and had to actually go and bring D-Klak into the getaway car.
Axel explicitly told them that there were to be no one-liners during the operation. Harold couldn't grasp that, and told D-Klak that they were there to take his order. Theodore told him to stick to the plan, and then also told him that they were there to take his order. Branar then pointed a gun at Klak, and the two other Skrall followed suit.
