Dr. Tomoki (Dr. トモウキ Dokutā Tomouki?) is Specter's partner in crime during Ape Escape 3. Due to a science experiment gone wrong a few years before the series began, Tomoki wears a Pipo Helmet underneath a giant yellow afro wig. After defeated by Yumi and Kei, Specter finds out and ridicules him. As a result, Tomoki switches his allegiance to Yumi and Kei, he is seen again on the space station promising to stop Specters plan and promises to see them again, secretly lamenting that the only way to stop it is to blow up the space station. Kei and Yumi witness the explosion and his apparent death as they escaped, only to discover he survived (as seen in the credits) as he revealed himself to Kei, Yumi and Aki in the TV Station. He is voiced by Nolan North in the American version.
- His special attack is "Luxury Beam!", in which he sweeps a large rotating laser across the battlefield.
