Super Mouse

Super Mouse (超マウス, Chō Mausu) was a Demon-level member of the Monster Association. He was one of the monsters sent by Gyoro Gyoro to investigate an unknown intruder, along with Showerhead and Unihorn. He was killed by Overgrown Rover.

Appearance
Super Mouse was an anthropomorphic mouse with white fur and a very muscular body. He was taller than Garou and had a long ringed tail. Similarly, his hands and feet also had ringed linings across them. Super Mouse also had featureless eyes with no irises and pupils, having a white sclera instead.

Personality
Super Mouse was a sadistic creature whom was rather confident in his abilities. However, he acknowledged the strength of stronger Dragon-level Mysterious Beings and was willing to work alongside other monsters when fighting opponents.

History
Prior to him joining the Monster Association, Super Mouse was a lab mouse who was constantly experimented on. As a result, his body mutated and he gained increased strength, speed, intelligence, stature, and limited regeneration. Sometime later, he would come to join the Monster Association and work together with Unihorn and Showerhead.

Monster Association Arc
While Garou and Tareo are walking away from Overgrown Rover, Super Mouse appears alongside Unihorn and Showerhead and attacks Garou. He deems Garou a warm up before the fight against the heroes. His comrades, Showerhead and Unihorn then attack Garou with their respective techniques, but the Hero Hunter easily counters and knocks them back. Super Mouse then throws a left jab at Garou, but the Hero Hunter blocks his punch using Whirlwind Iron Cutting Fist, creating several wounds. The monsters, however, stand their ground, expressing surprise at Garou's superb fighting ability as they have been all evaluated by Gyoro Gyoro to be Demon-level threats.

Garou is scornful of such arbitrary labels and declares himself a Dragon-level monster. Super Mouse scoffs at the notion, stating only the upper echelon of the Monster Association were at that level of strength. The three monsters then prepare their special combo they developed called the Demon Trinity Bursting Speed Thrust. However, Garou already experienced a similar technique against Stinger, and is able to easily deflect the attack, casting Unihorn off into the distance behind him. Unfortunately, the attack inadvertently hit Overgrown Rover. After the chewed up head of Unihorn is flung back at them, Super Mouse fearfully utters the cadre's name out of regret at having ticked off one of the association's leaders. In anger, the monstrous dog fires an energy sphere at everyone in the hallway. Showerhead attempts to stop the attack with his maximum water pressure, but he is quickly overpowered and vaporized. Super Mouse is confident that his regeneration can revive him, although the energy blast overwhelms him, and he meets the same fate as his comrades.

Abilities and Powers
As a Demon-level threat, Super Mouse was a powerful monster. However, he was easily overpowered by Garou and was completely helpless against Dragon-level monsters such as Overgrown Rover, and was ultimately obliterated by just one of the dog's energy blasts.

Physical Abilities
Enhanced Strength: Super Mouse boasted impressive physical strength, as he was able to shatter walls with ease.

Regeneration: Due to his time being experimented on as a lab mouse, he gained a limited degree of regeneration and was able to quickly regenerate from Garou's attacks. His regeneration has a limit, and this was seen when he was killed by Overgrown Rover's blast.

Fighting Style
Hand-to-Hand Combatant: Super Mouse fought mostly as a hand-to-hand combatant.
 * Combination Attack: Demon Trinity (三鬼一体, Sanki-itsutai)
 * Explosive Velocity Thrust (爆速刺し, Bakusoku-zashi): The attack utilized the powers of Unihorn, Showerhead, and Super Mouse. Super Mouse launches a transformed Unihorn forward as Showerhead continues to propel him with Jetstream. The attack is powerful enough to severely anger Overgrown Rover although Garou found it slow and compared it to Stinger's attack.

Trivia

 * Bomb would have beaten Super Mouse in one swift attack before the monster could even react.
 * The Japanese name for Super Mouse (超マウス, Chō Mausu) is written with the same kanji used for the Japanese translation of Nietzsche's philosophical concept of Übermensch or Superman (超人, Chō Jin).
