|Demon Bounty||Mission Alpha|
Madarai is a playable character introduced in Doom Dome Battle 2.
Madarai, an insane man whose sole purpose is to drive others insane and kill them afterwards. He sells their organs on the internet after doing so. At first he seems like a regular man until he lifts his suppressed self of a true serial killer. Madarai possesses immense strength, obtained by the use of drugs. He uses the chemicals in a serum that he injects in himself to turn him into a powerful beast-like creature, giving him sharp claws, huge muscles, a long slippery tongue and crazy hair. He is widely known, but no one knows who he truly is.
Madarai is a tank-like character. He attacks with his claws for most of his attacks, but also is seen to use his hair and tongue/teeth as well. He is a very fast character who can quickly leap at an opponent and attach himself to them for rapid attacks. He gains a boost in power when he takes some of his chemical drugs.
Madarai's Doom Attack is Overdose in which he takes too much chemical drugs and changes into a giant muscular version of himself and deals a few massive blows to the opponent, slamming them into the ground. When it KO's them he kicks their head off while their body is in the ground.
Doom Dome Battle 2
He is locked up in the mental asylum of Wildefort where Bibo visits him for answers, which leads to Madarai breaking out of the asylum to continue his hobby.
In this alternate future he takes a chemical overdose, but permanently stays in his buff muscular form. They manage to get him into the mental asylum again and put on a mouth cap to prevent him from taking more chemicals. He now lingers in the corridors of the abandoned asylum. When Alpha infiltrates it with Jeong, Madarai keeps stalking them. He eventually corners them, throwing Jeong to the side, breaking him, and battles Alpha. She manages to kill him in the end.
