Boros decides that earth is pretty fun planet.

Through sheer luck (or maybe divine intervention… cough cough PLOT), Saitama’s punch didn’t quite finish the job. Boros, clinging to consciousness with barely enough juice to stay awake, decides to have a little chat with the bald guy he was about to annihilate — and who nearly killed him. After a… let’s call it an... interesting exchange of words. Boros does some simple math. Saitama = strong. Strong = fun. Therefore, Saitama = fun. Earth = Saitama’s home. So by extension… Earth = fun. Hey, the math checks out. After asking Boros if he plans to cause any trouble and getting a simple "yep" (totally believable), Saitama shrugs, stares, and decides, "Good enough for me." bringing him over too city z, he is not aloud in saitama's apartment because, 1 he's massive as fuck, 2 his toster already lives there, 3, his toster would not be fond of the guy who yeeted city A moved in. plus, he got no suppresion armour, sooo saitama does not want to wake up to all his shit broken. so now, boros is broke, homeless and basically forced too be good or else he gets punched to the next anime over. sooo, he decides to find a house, and maybe some good opponents. ... And well… a lot of bullshit happens after that. At least he found some strong guys. atleast... TL;DR: Boros turns into a goody two-shoes. (yes, like one of those dragon ball what if's on youtube.) --- Author: After re-reading the OPM manga, and reading a certain genos x Y/N fic, I was suddenly in the mood to write something OPM, and after taking a while to think, I could not think of any ideas for Genos. But, there is another guy I also like. who I also find hot (don't question my tastes.), and is also a certified bad ass. boros, and well there is a lot of shit we can do with him, I mean, he was like only in like a couple chapers before becoming dust. So I give you this, my excuse to keep him around. Saitama pulling a Goku move and going "Eh, you can be good." and through the power of plot... he kinda gets there.
