The Sludge Villain's body is made out of mud by virtue of his Quirk. He has sharp teeth and big round eyes.
The Sludge Villian shows himself to be a seflish, cruel and sadistic criminal. He was bold enough to steal in broad daylight and flee the scene with various bystandards watching until he found out All Might was near. While trying to escape from the Symbol of Peace, the Sludge Villain had no remorse about trying to steal the bodies of two young men, a process that would have suffocated them to death. 
The Sludge Villain first appears fleeing the scene after he had robbed a bank. Unfortunately for him, All Might notices the villain and forces him to use the sewers to escape. While escaping, he decides to come out of the sewers to try and steal Izuku Midoriya's body. However, All Might catches up to him and blows him apart with his Texas Smash, and traps in inside two bottles.
While All Might is en route to hand the villain over to the authorities, he loses the bottle and the Sludge Villain is able to escape from his imprisonment. He eventually finds Katsuki Bakugo and decides to take control of his body for his Quirk. The villain proceeds to wreak havoc in the city with Bakugo's Quirk and none of the Heroes are able to stop him. Suddenly, Midoriya runs towards the Sludge Villain to help Bakugo even though he doesn't even have a Quirk. The Sludge Villain decides to attack Midoriya, but before he can do so All Might stops the villain and defeats him with the Detroit Smash. Bakugo is freed of his control and the Sludge Villain is taken into custody by the Police Force.
