I would Love to know more about Knife honestly!
As a table top NPC I have some hard and fast characterization rules for him to help me while acting:
I think the most important thing to know about him is that if he does not want to do something he simply will not! Changing his mind on something is usually a roll another player has to make.
Knife wants to be included. He does not always want to participate but he is happiest when he is invited and gets to watch. Maleficent rules. This means he gets wrapped up in things you might not expect, like watching the badlands gang (other npcs) light things on fire for fun, or watching people play poker, or knowing enough people to know who has a dog he can borrow ect.
He gets bored easily. This includes conversations he doesn't like. He will just exit a situation, conversation or change the subject drastically if he doesn't like it. He gets away with this way way way more than he should.
He has a huge ego but not enough lived experience to avoid looking stupid. So if I can feasibly make him do or say something Vash-like or technically true but ridiculous, I do it. Which is very funny because my character voice for him is very smooth and deadpan. Which is how I get dialog like "I think if you made pickles big we'd never need more pickles. I think this has legs." when talking to Tesla about their big/small quantum powers.
Knife loves Pickles. And Spicy things. And Coffee. He is stimulus seeking when it comes to tastes. He does not have to eat very often and he is extremely picky when he does. He doesn't like water (it makes his mouth wet). He will eat wasabi (usually in his coffee) and egg yolks(absolutely not in his coffee). I think there are a few other things Tesla got him to eat when he was injured and needed to but I can't recall.
when he feels more pain than he can handle he just stops feeling it. He thought he was going to die for realsies when he was injured and it happened. It's unclear if this is something Tesla when they 'fixed' him.
He is very keen about morals. The player characters have hearts of gold but they are not peaceful or particularly good. His moral development is entirely in their hands and its been interesting. He has learned that 'people don't have to make sense' and that 'everyone is protecting what they have' and knows that 'killing too easy and often is bad' he will tell pcs to their face if he thinks they are good people or not, but it doesn't yet have a bearing on wether or not they are friends or if he'll be pleasant or helpful or not. Tesla has decided to stick with the pcs and that means this is where he is, why would he be anywhere else? Do you see his logic?
Every once in a while when the gang is trying to plan something Knife will say something like "If I was a warlord with a load of guys who wear neon and have battle trucks I'd X, Y Z" or "If I was cult leader with a bunch of super soldiers with cross guns I'd do x" and from his pov he's just giving his two cents to be helpful but the rest of the pc know who he was and they always pause and go "Worrying, but great point!"
he has no idea who he was or what he was like before July. yet.
He thinks he is entirely logical and reasonable at all times :)
