Garou is introduced as an antagonist with a confident, vindictive characterization driven by a deep hatred for heroes. He hates being insulted and will attack anyone who offends him. He thinks highly of himself and uses that assertion to threaten high-ranking personnel such as heroes and Sitch. He will also attack low-ranked heroes and Hero Association staff members if he encounters them. Garou hates those who are popular, as he believes the popular ones will always win in the end.
