Overview
You bunch with your little game of 'Let's pretend to fight for justice' can't win against a truly strong opponent, nor can you protect anything.
— Sonic's view of heroes[1]

Speed-o'-Sound Sonic (音速のソニック, Onsoku no Sonikku), more commonly called Sonic (ソニック, Sonikku), is a recurring villain and occasional anti-hero. He first appeared as a bodyguard hired by Zeniru.[5] He is a former member of the 44th Graduation Class of the Ninja Village, nicknamed The End (終わり, Owari; Viz: The Final).[6] Sonic is also a self-declared eternal rival of Saitama.[7]

Appearance[]

Sonic is a slim young man. His long black hair is normally tied up in a topknot, and bangs fall over his face. A noticeable feature of his is the purple marks underneath his large gray eyes. He usually wears a tight black latex bodysuit highlighted by metal plating on his shins, arms, shoulders, chest, and waist, as well as a long purple scarf that falls to his legs. During his fight with Genos, Genos ripped his scarf and tore off his topknot, leaving the ninja with short hair.[8] In the manga, when Sonic later appears during the fight between Saitama and Tatsumaki, he is seen with his long purple scarf and long hair again.[9]

Personality[]

Despite his normally calm demeanor, Sonic loves fighting, he is motivated by bloodlust against weak opponents, the thrill of battle and his superiority against strong opponents he can beat, as well as competition against a strong opponent he can't beat.

Sonic excited to test his skills on Saitama

Sonic has a large ego, when he sets his mind to killing someone he refuses to give up until he succeeds and is unwilling to tolerate the existence of someone more capable who has defeated him.

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.[10]

To that end, he holds considerable disdain for the world, being quite cynical, especially towards heroes. 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.

Despite the way he presents himself, Sonic has a soft side, something seen when training to fight against Saitama. 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. 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. 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. 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.

Due 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.[11]

Sonic also respects Saitama for fighting monsters and even promised to himself to never fight Saitama while the hero is fighting monsters. 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. 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.[12]


In his youth, Sonic was a very passionate boy who strove for a better life and did not allow the torturous training of the Ninja Village to turn him into a machine. He wanted to become the highest-ranking officer of the Ninja Village to change the institution and allow the trainees to live more freely.[13] He expressed the idea that the thing with true value is the idea to live one's life freely and hoped Flash would assist him with his dreams.

Sonic's disdain for heroes appears to stem from an incident at the Village nine years ago, when Blast arrived to eliminate the hidden sect, massacring all of the Class 5 ninjas regardless of their age. Sonic was able to escape thanks to being the strongest in the group, although the experience was rather traumatizing as it changed his perception of the world and heroes.[14] He believes that the moniker of "hero" isn't really suited for anyone, feeling none are worthy of such a lofty title. Furthermore, Sonic feels what the hero industry does isn't at all different from what the assassination business of the Ninja Village did, with heroes merely acting as though they do it for the greater good.

Greatly loathing individuals who think highly of themselves because they are more powerful, often touting it as incentive to be self-righteous jerks.[14] Going on to voice his general disgust and appallment at how the Hero Association and especially Neo Heroes methods make them more rotten than the criminal underworld when the latter recruited degenerates and the former tried to strike a deal with ne'er-do-wells and psychopaths as a means to an end.[15]

Abilities and Powers[]

As a veteran ninja and assassin, Sonic is a master of ninja weaponry, possesses incredible amounts of speed, and is adept at hiding his presence. Fubuki commented that Sonic's fighting ability is that of an S-Class individual.[4] However, he is rather helpless against Dragon-level monsters, as seen in his fights with Gale Wind, Hellfire Flame, and Energiser. After his defeats by Saitama, Sonic has become considerably stronger due to constant training. He is now capable of holding his own against Flashy Flash, a powerful S-Class hero, and withstanding one of the hero's ultimate techniques. Nevertheless, Sonic is still weaker than Flash, as most of the Heavenly Ninja Party members, whose mindset is to first target the weakest ones while facing multiple foes, ganged up on him first after witnessing their duel.

As a child, he was revealed to have been rather weak in comparison to other ninjas, as he was always placed in the lowest class and was unable to advance to higher classes despite being given the harshest training in Class 5. However, Sonic revealed that like Flashy Flash, he only acted like he was weak to receive the harshest training.[16] Additionally, while fighting alongside Flashy Flash, Sonic was strong enough to eliminate all 21 members of the Heavenly Ninja Party. With the Legendary Demon Blade, he could easily defeat Shunpo, a Dragon-level threat and Machine God battle robot created by The Organization.

As time passed since his first appearance, Sonic became significantly stronger and faster due to his fights with Saitama and constant training. This was shown when was able to keep up with Flashy Flash during their brief battle, managing to react to and defend against one of the hero's ultimate techniques.[20][21]
