A deserted structure in an unspecified spot where Speed-o'-Sound Sonic lives alone, keeping a nearby forest as his private training ground. The manga and webcomic close the place out differently, one leaving it in ruins and the other simply emptied and abandoned.
The site is a run-down building at an undisclosed location that the story never pins down. A stretch of woodland grows close at hand, and Sonic frequently retreats there to sharpen his skills.
Sonic leaves this refuge to drill in the forest, where two elder graduates of the Ninja Village, Gale Wind and Hellfire Flame, hunt him down and pitch membership in the Monster Association, pressing a monster cell into his hands. Back home he broods over his inability to eclipse Saitama despite relentless practice, then resolves to consume the cell.
Later, during the Ninjas Arc, the Heavenly Ninja Party corners him at the hideout and orders him to bait Flashy Flash to the spot. Empty Void afterward perches atop the roof only to be crushed the instant he swings at the arriving Saitama. Blast's portal soon gathers Saitama, Overgrown Rover, Flash, Sonic, and the ninja party together here, and when Byakko and Genbu erupt from the Rift in Spacetime, the pair wreck the building and surrounding city blocks before Blast and Void banish them.
In the webcomic's telling, A and twenty-nine subordinates later ambush Sonic on the premises hoping to seize his body for the Neo Heroes, but he wipes out every attacker and forces A to retreat.
Sonic's Hideout is a deserted structure at an unspecified location where Speed-o'-Sound Sonic lives alone, keeping a nearby forest as his private training ground.
In the manga, Byakko and Genbu erupt from the Rift in Spacetime at Sonic's Hideout and wreck the building along with the surrounding city blocks before Blast and Empty Void banish them.
Gale Wind and Hellfire Flame, two elder graduates of the Ninja Village, hunt Sonic down in the forest near his hideout and press a monster cell into his hands while pitching him on joining the Monster Association.
In the webcomic, Sonic's Hideout is left simply emptied and abandoned rather than destroyed, though A and twenty-nine subordinates later ambush Sonic there before he wipes them out and forces A to retreat.
Volume 15 appears to show a toilet that Sonic makes use of somewhere inside the building at his hideout.
