Garou

The symbol of fear: Good, Evil, I will reject them both. Cosmic Garou is the strongest enemy in all of One Punch Man that any of the heroes have faced. At one stage, he unlocked his 'Saitama Mode', which allowed him to copy Saitama's move set and strength, making it so only the Caped Baldy himself could take down this walking calamity He will kill heroes and Monsters without any mercy
