Befitting his appearance, Goto has a very sadistic, brutal, and bloodthirsty personality. He openly admits that he wants to use his Quirk freely to kill. Goto enjoys killing and tormenting his opponents, often saying, "Show me your blood!". Unlike most of the other members of the Vanguard Action Squad, he joined the League of Villains just to let loose with his brutal tendencies rather than following Stain's ideology. Goto's signature trait is his overconfidence, which later proved his biggest flaw. Goto believed himself superior to Izuku Midoriya because his Quirk's augmentation powers were more potent than Izuku's. This superiority complex resulted in Goto using only part of his power to toy with Izuku. His overconfidence is also what caused him to become distracted during their fight. Izuku could land a powerful smash against him on two separate occasions because he allowed himself to be distracted by Kota Izumi. Despite his ego, Goto does compliment Izuku's strengths. After getting hit by a full-power smash, Goto admitted Izuku was powerful and decided to stop holding back. However, this never stopped him from taunting Izuku during their bout. He later gains a twisted sense of respect for Izuku, being overly eager to fight him again during their second encounter. He also gets bored quickly against enemies that are unable to match him and inquires if there are any more powerful fighters around.
