Speed-o'-Sound Sonic

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.

Speed-o'-Sound Sonic (音速のソニック, Onsoku no Sonikku) is a villain in the series, first appearing as a bodyguard hired by Zeniru and declares himself as Saitama's eternal rival.

Appearance
Sonic is a slim young man with a feminine face, long black hair tied up in a topknot, and large grey eyes. A noticeable feature of his are the purple marks underneath his eyes. He usually appears wearing a tight black bodysuit highlighted by metal plating on his shins, arms, shoulders, chest, and waist, as well as a long purple scarf. After the fight with Genos, Sonic loses his topknot and is left with loose shortened hair.

Personality
Despite his normally calm appearance, Sonic loves fighting strong opponents as shown by when he gets a "child-like smile" on his face when he first meets Saitama and has two of his attacks blocked, earlier calling this his "bad habit." He seems to be very quick to act as he attacks Saitama on their first meeting without letting him explain the situation.

He is persistent, even when he realizes that the opponent is much stronger than he is. When Sonic recognizes an opponent as his rival, he does whatever he can to initiate the battle, such as causing massive property damage and endangering the surrounding citizens in order to get Saitama to fight him. He also seems to have no qualms with killing as shown when he kills Hammerhead's gang and even goes as far as to take pride in the fact that he never lets a single person live.

He seems to be rather disdainful of heroes. When he meets Genos, he tells him that heroes can neither win against a truly strong opponent nor can they truly protect anything. However, unlike Garou, he does not go out of his way to attack heroes.

Abilities and Powers
As a ninja, Sonic is adept at hiding his presence. He has displayed proficiency with multiple weapons. Fubuki commented that Sonic's fighting ability is that of a S-Class individual.

How Sonic obtained his ability is unknown, but so far the only person shown to be able to keep up with and surpass his speed is Saitama.

Enhanced Strength: Despite his thin appearance, Sonic's power doesn't only lie in his speed. He also has superhuman levels of strength, being capable of dislocating a man's shoulder simply by walking into him.

Enhanced Durability: In addition to his speed and strength, he is capable of taking large amounts of damage as shown when Sonic fought the Sea King.
