Sith AU & Enemies to Lovers & Possessiveness Headcanon: Okay so both Anakin and Obi-Wan are Sith, but they are also enemies, always fighting against each other to prove they are the best, the strongest the evilest, the only one worthy of being considered a true Sith. Funny thing tho? They are super possessive about each other despite still being enemies. Like, some random Jedi hurts Obi-Wan? Anakin goes fucking berserker! He kills the Jedi, puts their severed head on a stick and presents it in front of the first jedi temple he can find (and also probably sets fire to the temple because sure, he has to make everyone remember that Obi-Wan is HIS enemy; but he still has to prove to Obi-Wan that he's the best Sith there is). Nobody would think Obi-Wan to be just as petty as Anakin, but lo and behold, he finds out Anakin's Master is being a manipulative bitch that tries to treat Anakin like he's a pet and Obi-Wan puts his big brain into action. He's not gonna kill Sidious, OH NO. That would be TOO LITTLE. He wants true revenge! So Obi-Wan finds out what Sidious wants the most and he kind of helps him almost get it in a subtle way, so that Sidious doesn't even realize that someone else is plotting behind his back. And then, at the very last moment when Sidious can basically already taste what he'd always wanted, Obi-Wan makes sure that he loses it and that there would never be a way for him to get it, not even if he fights an eternity to try and get it all back. AND THAT? That is the moment when Anakin goes from "I WANNA FUCKING KILL THAT MAN!" to "I'D KILL TO FUCK THAT MAN!"
