Oh boy, we’re fixing them now? That’s all swell and good but in this AU everyone is still capable of giving consent, so you can’t just drag your hybrid to the doctor and say “fix them”. But, I don’t think Hanzo would want kids, and since Genjis body is all messed up he thinks it’d be better for his health anyway. (but in this AU I also think… cyborg Genji is a thing but not because Hanzo killed him. I have a few ideas on that but I don’t need to use this post for that.)
They still mess around with each other like any brothers would, but for the most part they get along well. Sometimes, on quiet, chilly, rainy days, they’ll snuggle together and Hanzo will groom Genji. Genji protests like “nooo I can groom myself just fine” but Hanzo responds with “just let me be a big brother. You didn’t put up this much of a fight when you were a kitten.” Because yes Hanzo babied the shit out of Genji and loved grooming him when they were little.
Genji can’t get too tubby because he needs to maintain a good diet to keep his body working okay. But, Hanzo probably puts on a few pounds. I suspect he goes out to buy cakes and just goes to town on them.
Genji absolutely loves to cuddle and has been affectionate since the day you got him. Hanzo was a bit of a tough cookie, though, and needed to gain your trust before he’d let you lay a finger on him. Now, he feels safe in your arms and gets a feeling of contentment he hasn’t had in a long time. Sometimes, he’ll even sneak into bed with you and cry out some of his frustrations. A good cry always makes him feel better. ❤
Genji is also more susceptible to falling into the “pet” head space. There are days where he just wants to let loose and rely only on instinct so he’ll be much more cat-like. Hanzo is too prideful to act in such a way. The most he’ll do is purr and mew and rub against you to get your attention.
