Red Greymon is grey skinned and has two red horns on either side of his head. He is fairly knowledgeable about the Name Hunt Station and its Festival[1] but appears to have difficulties with his memory.[2]
He explained to Viole's team about the Festival of the 'Name Hunt' Station and then accompanied Viole and Koon during their journey through the Festival island and Kaiser's Gallery to take the latter's name. He then watched as Viole took Kaiser on and unhelpfully revealed Kaiser's two trump cards to Koon after Viole experienced both of them first hand, much to Koon's annoyance. He also wondered why Koon referred to Viole by the other name "Baam".
Notes and Trivia
He may have been named after the Digimon Greymon.[3]
