Background[]

Not much is known about Speed-o'-Sound Sonic, from all we know he is a so-called eternal rival of Saitama and is a S-Class criminal. 

Powers & Abilities[]

  • Immense Speed and Reflexes: Sonic possesses superhuman speed and agility. When confronting the Paradisers, he was capable of easily moving faster than they could react, and decapitating every single member of the group apart from their leader Hammerhead, in only mere moments. He was also able to easily dodge all attacks from Deep Sea King, a Demon-level monster that could outmaneuver A-Class heroes effortlessly, only having difficulty when the sea monster entered its true form. During his fight with Genos, an S-Class hero, Sonic was capable of keeping up with the cyborg in combat, with both of their movements being so fast that Fubuki could not even see any of them. 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.

  • Enhanced Durability: Sonic's durability is greater than the average human's. He withstood Base B's shoulder and dislocated the prisoner's shoulder in turn. During his fight with Flashy Flash, Sonic's durability was shown to have significantly increased, and he was able to withstand Flashy Flash's Flashy Kicks. He also withstood Brawny Muscle's special punch, who can be considered the Heavenly Ninja Party's physically strongest member. He credited this durability to having experienced Saitama's attacks over a dozen times.
  • Ninjutsu Master: Sonic is a master of ninjutsu and has knowledge of various deadly techniques.
    • Full Frontal Attack: Sonic takes a low stance and rushes forward at speeds that make him impossible to be seen. The effect of this attack is not known because it was interrupted by Hammerhead.

      • Scattered Flash Slash: Used in a conjunction with Four Shadows Burial; Sonic attacks his opponent with his four afterimages. This was used against Genos. However, the effectiveness of the attack is unknown, as Saitama interrupted before Sonic could hit the cyborg.

    • Thirteen Shadows Burial: Sonic creates thirteen afterimages using a special movement technique.
    • Serious Side Hops: Sonic can perform an inferior imitation of Saitama's killer move, Serious Side Hops. Sonic hops from side-to-side rapidly. Doing so creates a multitude of afterimages in the form of a wall. Sonic then charges at his opponent, however, the resulting shock wave was not strong enough to take down any members of the Heavenly Ninja Party and left Sonic exhausted.
    • Speed of Sound Electric Discharge Fist: Sonic extends his finger and pokes his opponents on the head, unleashing powerful shots of electricity and killing them. This move managed to easily kill all the Neo Heroes sent to eliminate him despite possessing their battle suits.
