Super Mouse

Supermouse is a member of the Monster Association in the manga. He is a demon-level monster who briefly appears to fight Garou along with two other monsters.

Apperance
Supermouse is an anthropomorphic mouse with white fur and a very muscular body.

Personality
As expected of a monster, he is rather confident in his abilities and sadistic as well. However, he acknowledges the strength of higher Dragon-level mysterious beings, and willing to work alongside other monsters when fighting opponents.

Biography
Prior to him joining the Monster Association, Supermouse was a lab mouse who was constantly experimented on. As a result, his body became mutated and he gained increased strength, speed, stature, and limited regeneration. Sometime later, he would come to join the Monster Association. While Garou and Tareo were walking away from Overgrown Rover, Supermouse appeared alongside Unihorn and Showerhead and attacked Garou. Supermouse deemed Garou a warmup before the fight against the heroes. Showehead and Unihorn attacked Garou with their respective techniques, but Gaoru easily dispatched both of them. Supermouse threw a right jab at Garou, but the Hero Hunter blocked his punch using the Whirlwind Iron Cutting Fist, creating several wounds. Ther monsters, however, get back up, and commend Garou for his superb fighting strength and his ability to measure the strength of opponents. Garou declares himself a Dragon-level monster, but Supermouse scoffs at the notion, saying 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 blast. But what they didn't realize was the attack inadvertently hit Overgrown Rover. The monstrous dog then proceeds to fire an energy blast that captures everyone in the hallway. Showerhead attempts to stop the attack with his maximum water pressure, but he is vaporized alongside Unihorn. Supermouse 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
Being a Demon-level mysterious being, he is naturally a strong fighter and was able to take some blows from an evolving Garou. However, he is completely helpless against Dragon-level monsters like Overgrown Rover and was obliterated by just one of his energy blasts.

Enhanced Strength: Supermouse boasts impressive physical strength, and was able to punch walls with complete ease. Enhanced Speed: Being a Demon-level monster, Supermouse has a high level of speed.

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. But his regeneration has a limit, and this was seen when he was killed by Overgrown Rover's blast.
