//Actually, while I'm at it, I'm going to post some of my favorite headcanons for each active muse to start things off.
He doesn't like to kill. It's never his immediate goal, and he only does so when he sees no other option. Killing the Arishok, who he had seen as a friend of sorts, was only done because he was backed into a corner, and it avoided potentially even more deaths being on his head. Still, he hated himself for it, and he hated that statue even more. This is also part of why Anders's choice to involve him in gathering those ingredients made him feel more deeply betrayed and why he nearly spiraled out in panic at Sebastian's ultimatum. He didn't want to kill anyone, but especially not a (former?) friend, and especially not the man he owed his brother's life to...
This is probably going to be the most lighthearted one here, and I'm not sure if I already mentioned it on his individual blog, but I just want everyone to know or remember that this poor amnesiac little elf didn't even know his own name when he woke up. Unfortunately, due to the legend now surrounding him, everyone else addressed him as if they knew him, and for a brief period of time, he had to deal with the disappointment and horror of thinking his name might be "Harold".
Less of a headcanon than legitimately a way you can interpret the canon events of the show, but you know the whole Trigon arc? Raven did not think she would survive. She did not think her friends would find a way to defeat her father and undo his destruction of Earth. She literally sacrificed herself and the rest of the world to protect the only real family she'd ever had. And given that she wasn't even sure if the protection she'd placed on them would work, at the very least, she wanted to protect herself from being able to experience their deaths.
So, this was never intended and was actually a recent discovery, but I do pride myself on doing more research than the CW writers when it comes to scientific plausibility (no "absolute heat" gun, that struggles to even melt metal doors btw, here). Anyway, while researching fire, heat, motion, density, and calories, I had the startling realization, that in order for Leia's powers to plausibly work without killing her, she'd need new organ structures that make her no longer completely human, she might be somewhat immortal (probably not invulnerable, though), and if she ever reached real absolute heat, she'd create a black hole, create a new universe, and/or break the laws of physics as we know them. She doesn't realize any of this, and she probably won't handle it well if she learns about it, but that's science for you! ✌️
So, there's one kinda fucked up thing in Bruce's past that almost nobody knows about, and that's the fact that he almost killed Joe Chill before he became Batman. When he didn't go through with it, he confided in exactly one person (Alfred by default, but potentially Harvey in threads where they were childhood friends). What nobody but Bruce knows (now that Joe Chill's dead), is that when Jason died, and Bruce was faced with the first murder of a direct family member since his parents, he decided to ask the man who helped create his no-kill rule what he should do about wanting nothing more than to break it. There's a lot more to this, but the short version is that Joe kind of avoided answering but strongly pointed Bruce towards not going through with it by asking how Jason would feel, and Bruce planned to ignore that, but while beating the Joker to death, he couldn't stop thinking about that question and restrained himself from going through with it for the sake of not tainting Jason's memory. Needless to say, the whole Red Hood thing had him feeling extra fucked up.
