"Grimey" (A Flash Beorn Our Eyes) "Kaliban" (A Flash Beorn Our Eyes)
After the Prodigy saga, Doomulus Grime was marooned on Two's planet and eventually teamed up with Unten to get off the desolate planet in A Flash Beorn Our Eyes.
Doomulus Grime is heavily cloaked, and caped, with armor both above and underneath his cloak. He wears long gloves and boots and a mask, obscuring his skin, and face, which resembles that of a crocodile. Part of his body is machine, mostly his upper right face, left arm, right thigh, and lower left leg.
In Underground (2015), he has a new outfit that adds a gas mask-like mechanism to his mask and his tail is now more circular. The outfit itself is similar to a body suit.
Makes a quick cameo as a skeleton that menaces Unten in a vision in Chapter 10 of the story.
Doomulus Grime was once known as Doomulus Nine, and was a member of the Doomuli organization, which ruled many solar systems in the galaxy. As holding the Doomulus Number of Nine, he was the second-most powerful in the group, second only to Doomulus Zero. Though he was the second-most powerful, Nine actually was only biding his time to steal the GigaDrill, which was capable of absorbing the nutrients of a land's soil and transfer it to a living organism. Planning to use this to give himself extreme power, Doomulus Nine stole the GigaDrill, rechristened himself as Doomulus Grime, and fled. Doomulus Seven and Doomulus Eight went after him, but they were defeated. After this, Doomulus Nine escaped to obscure planets to avoid the other Doomuli.
In Fissure, Doomulus Grime has already had the GigaDrill for several years, and is planning to use the unusually fertive soil of Zeon to finally achieve his goal of supreme power. Grime easily takes control of the primitive Zeon kingdom for several years, due to the time it takes for the GigaDrill to work.
During the end of the game, the GigaDrill had almost completely filled up on power, getting to 99%. Grime used a machine to transfer this immense amount of power to his body, becoming a supercharged monster in the process. Despite this power, Unten defeated him, which made the machine suck his power back until Doomulus Grime's power was completely depleted, and he collasped into dust. The GigaDrill then fell into the Fissure, which caved in. This leads to the setting of Underground.
Doomulus Grime's backstory is revealed in the first part of the game. He is a robot that was created by Unten's real father that became self aware. He is responsible for Unten being adopted, as he kidnapped Unten, flew away, and dropped him on somebody's porch. He flew to an abandoned planet, where he found a machine that duplicated himself several times. The planet then became the Doomuli Organization.
Seven years later, he changed his name to Doomulus Grime, stole the GigaDrill, and flew away from the Doomuli Organization because the robots were turning evil. Doomulus Seven and Doomulus Eight followed him, but they were hit by asteroids. He crash landed on Zeon, where the GigaDrill started by itself. He dove after the drill, and it electrocuted his systems, turning him evil.
- The version of Doomulus Grime seen in Fantendo Genesis is called "Skeleton Grime" according to artwork.
