Speed of Sound Sonic-0
Whenever I face you, I cannot picture myself winning for some reason... Unless I defeat you and wipe off this thought I cannot move on.
~ Speed of Sound Sonic


Speed of 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 Mr. Monier. He supposedly grew up in a ninja village, honing his skills to near perfection. He views Saitama as his eternal rival, ever since the hero "defeated" him in a rather embarrassing manner.

He 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.
