Keramon

Keramon is an Unknown-type Digimon with a large mouth, he can eat more than 100 million bits of data in the space of a second, and does this by entering a computer and taking up all the space, terminally overloading the data. With a simple-minded, innocent character, even destruction is quite likely a game for him. Keramon appears to have a joker's collar around his neck, and underneath it's mouth, it has what resembles a second set of eyes, resembling a face in grief.
