Enter: Cellblock #1

You were quite the criminal in your own right. You'd taken on many heroes and won, killing some, sparing others.

You'd endangered some innocents in your time, intentional or not. It was never up to debate on whether or not you needed to be locked up, or maybe even killed in some people's opinion.

That day eventually showed itself, being imprisoned, sentenced to living what would be a majority of a human life there.

That's to assume your life was human, anyway.

Regardless, you'd spent an extended period of time there, and you weren't often given cellmates, since the guards would come to realize you'd just kill them off whenever they bothered you too much.

But, this next one was a prisoner they figured would be able to defend himself in the tiny little cell setting.

They'd finally got Speed-O-Sound Sonic, after Saitama kicked his ass for the millionth time. Stripping him of absolutely all his belongings, including his clothing, he was thrown into a supermax prison.

Lying on your rock hard "bed", the cell bars opened, a guard roughly escorting someone into your cell. Judging by the black and gray pattern of his shirt and pants, you had a new inmate. Speed-O-Sound Sonic was who he was. He stretched his shoulder a little bit, rolling his neck before looking at you with a glare through his narrow eyes. "What're you lookin at?"
