I think this is all the characters I've ever had bar two.
Lawful Good: Smiley, from Titans. An ex-secret service agent, who got employed by a superhero organization. He had a heart of gold and cared greatly for the lives of others, willing to sacrifice himself for everyone. This was especially easy because he was functionally immortal.
Neutral Good: Bug-girl, with a picture of Spider-Gwen because I didn't have a faceclaim and this is close enough I guess. Bug-girl was my Redux character that I used fairly shortly, but enjoyed the concept greatly. She fits neutral good, because she obeys the law most of the time, only breaking if necesarry. She cares for the innocent, and tries to beat down on thugs, but had the idea of controlling the violence she would use. In practice, she wasn't even able to be an actual threat, no matter how violent she would've gotten.
Chaotic Good: Maria, from Venice: Masks & Monsters, with a random model fitting her description as the picture because I barely use faceclaims. Maria does not much care for the law, preferring to work at night, by means of threats, and provocation. She's true however, to her honest working business-family, and generally tries to improve the area around her. Only beating up those who she feels deserve it. She's maybe a bit too good for the city, but luckily she's not too naive.
Lawful Neutral: Niklas, from Dust, with Jason Momoa as Conan as the picture, because again, I didn't have a faceclaim, and this came close. He's Lawful Neutral because he doesn't care for which side he plays, as long as he gets what he wants from it, a challenge. He does however uphold a personal code of honour, and lives by it completely. Anyone overstepping the bounds of this code he sees as inexcusable.
True Neutral: Griffin from Legends of Abyllia, and yes, I did use a somewhat well-known actor as a faceclaim. He's a true neutral not by intention, but because of personality. Remaining a true neutral force isn't something he adheres to because he believes it to be a good state, but because it allows him to scratch his greatest itch: his hunger for knowledge. He would follow laws if possible, but has no qualms about stepping out of those bounds if it means he can discover more. He tries to approach everything objectively and positively, seeing everything as a viewpoint with it's own values, instead of binding them to evil or good.
Chaotic Neutral: Okay, so I've put down Carl Burk, my Railways character, but I'm quickly realizing he doesn't fit this place at all. I pinned him here, because his naivity gave him a bad understanding of what law should be, and he could be swayed to do bad things, but I quickly changed my mind and feel like he's actual lawful good, which is quite the change. He sees the words of others as law, if they tell him something, he assumes it to be true. He wouldn't break a rule for the life of him, but if someone says the rule is different, the rule changes for him, making it fit his lawful good style. Not fixing the picture, though, because lazy.
Chaotic Evil: Emmett from Gunpowder. Emmett is chaotic personified, caring for no laws at all, just doing things because he feels like it. If there is someone who doesn't want his personal freedom limited, it's Emmett. He'll switch sides if he thinks the other side is more fun, but generally, he chooses neither and just annoys both. He's evil because he gets joy out of the adrenaline rushed of being traced, or pissing off an opponent, and the stronger they are, the better. His actions are never beneficial to any greater good, or any person that isn't himself. He will commit unspeakable crimes just to provoke people. He would also not do a good deed if he didn't benefitted from it in a way that influenced his surroundings negatively, because stabilizing a situation would be boring. If a group of thugs were hanging someone, he'd see the hanging as a distraction. The only reason he would save the hangman is if it would piss the thugs of more than just a good kick in the back and an insult. Emmett actually strifes towards a more aggressive, evil world, because it allows him to experience more rushes.
