Ironically, he is also rather judgmental as he assumes Tatsumaki exploits her childish cuteness and that those with benign appearances are weaker than himself, displayed in his fight against Saitama and Kamikaze. He holds a very negative view of the Hero Association and some S-class heroes after observing how they treat a powerful hero like Saitama like a low-ranked and worthless hero because of his looks. Sonic also respects Saitama for fighting monsters and even promised to himself to never fight Saitama while the hero is fighting monsters. It is unclear as to how far this side of him goes to, as he was willing to warn Genos of the Deep Sea King, yet fought him when Genos interfered with his battle with Saitama.ĭue to constantly losing to Saitama, Sonic is shown willing to do anything, even trading his own humanity, to defeat him by becoming a monster through the consumption of a Monster Cell provided by Gale Wind and Hellfire Flame, although he feels that becoming a monster is equal to death, as he will be no longer human.

When Sonic leaves to search for Saitama, he gives his words of wisdom to Frank, saying that if he is too confident in his fighting style and loses, the result will always be the same.

While he is pacing himself, Speed-o-Sound finds and befriends a little piglet as well, naming it Ino, thus showing his more noble side. During this period, he spent a great deal of time with Frank, a hunter who had almost been killed by a bear and confides with him his inner turmoil. As shown when meeting Genos for the first time, he tells him that heroes can neither win against a truly strong opponent nor can they truly protect anything.ĭespite the way he presents himself, Sonic has a soft side, something seen when training to fight against Saitama. To that end, he holds considerable disdain for the world, being quite cynical, especially towards heroes. Sonic has no regards for human life other than his own, and even takes pride in the fact that he has never let an opponent live. Sonic has a large ego, and when he sets his mind to killing someone, he refuses to give up until he succeeds, unwilling to tolerate the existence of someone more capable who has directly beaten him. Sonic excited to test his skills on Saitama And thus begins the story of One Punch Man, an action-comedy that follows an eccentric individual who longs to fight strong enemies that can hopefully give him the excitement he once felt and just maybe, he’ll become popular in the process.Despite his normally calm demeanor, Sonic loves fighting, motivated by bloodlust against weak opponents, motivated by the thrill of battle and his superiority against strong opponents he can beat, and motivated by competition against a strong opponent he can't beat. Genos proposes that the two join the Hero Association in order to become certified heroes that will be recognized for their positive contributions to society, and Saitama, shocked that no one knows who he is, quickly agrees.

This all changes with the arrival of Genos, a 19-year-old cyborg, who wishes to be Saitama’s disciple after seeing what he is capable of. In fact, all it takes to defeat evildoers with just one punch has led to an unexpected problem-he is no longer able to enjoy the thrill of battling and has become quite bored. Now, Saitama is incredibly powerful, so much so that no enemy is able to defeat him in battle. In order to pursue his childhood dream, he trained relentlessly for three years-and lost all of his hair in the process. The seemingly ordinary and unimpressive Saitama has a rather unique hobby: being a hero.
