One-Punch Man Wiki

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.[1] He was killed by Overgrown Rover.[2]


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.


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.


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.[3]

Monster Association Arc[]

Garou blocks Super Mouse's punch while simultaneously retaliating

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.

Super Mouse regenerates his wounds

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; Viz: Triple Demon)
    • Bursting Speed Thrust (爆速刺し, Bakusoku-zashi; Viz: High Speed Shish Kebab): The attack utilized the powers of Super Mouse, Showerhead, and Super Mouse. Super Mouse launches a transformed Unihorn forward as Showerhead continues to propel him with Jetstream. Garou found it slow and compared it to Stinger's attack,[4] though the attack was powerful enough to bother Overgrown Rover.
