Butchlander Hanahaki Disease AU with Homelander who has always craved love, looking for it in all the wrong places, falling in love with his nemesis Billy Butcher who hates him and wants him dead. All the emotional hurt and angst in the world with Homelander's already unstable mental health declining further into deep depression and self-hatred. His physical health deteriorating slowly as well, because even the strongest supe alive isn't immune to the deadly flowers blooming inside him.
Butcher finds out and is gleeful, rubbing it in Homelander's face when they meet. Saying, that it's no wonder the supe has fallen victim to the sickness caused by one-sided love, because who could love a monster like him?
At this point Homelander is already quite far gone with the disease, and hearing the object of his love telling him that he's "an unlovable cunt" causes Homelander to start violently coughing and vomiting a blooming Trillium recurvatum. Looking up at Butcher with wide and terrified eyes, Homelander takes wobbly flight.
Naturally, Butcher doesn't recognize the crimson flower, coated with more crimson of Homelander's blood. But he takes a photo of the mess, and when he shows it to the Boys, they make a reverse image search.
Trillium recurvatum. Bloody Butcher.
And when all heads turn to look at Butcher, there's not much else to say than, "Fuck me", paired with a diabolical grin. Because Butcher just found a way to finally kill the worst supe cunt on Earth. And what a poetic way, too. Homelander destroyed the love of Butcher's life. Now Butcher's going to do the same to Homelander with his mere existence.
But a supe of Homelander's caliber doesn't succumb to any illness or ailment nearly as fast as a regular human would. So, there's a lot of time for Butcher to find more dirt about Vought, since getting rid of Homelander is only one part of dismantling the megacorporation.
So, one day searching an abandoded facility that looks like it had been a lab of some sort at one point, Butcher stumbles on a box with old VHS tapes simply named "John #001", "John #002", "John #003", and so on.
Butcher begins watching the first tape, where there's a small blond, blue-eyed baby that makes Butcher feel at unease. The feeling increases with every video as the child grows and is subjected to absolutely inhumane conditions and torture. And when the child finally gains blood red eyes, shooting lasers from them, there's no doubt about the child's identity anymore. John is Homelander.
Butcher's conflicted. Very conflicted. Because he has this image of Homelander as a ruthless and sick psychopath set in stone. But these videos have made his conviction waver.
So, after all the emotional hurt and angst (not depicted here, because I fail), there's a happy ending with Butcher having snatched Vought's crown jewel right under their nose, slowly warming up to the man known as John, finally returning his feelings, and becoming a real family with their son Ryan.
