I would swap out lightning dust and discord.

The Evil section needs some work

Just a few nitpicks:  
Spike would probably be more neutral good.  
The Chimera, in my opinion anyway, is probably closer to chaotic neutral–she’s mostly a predator, looking for a meal, but she’s not above messing with her prey a little either, nor is she above eating a sentient lifeform (like a pony).  
And Gilda and the Diamond Dogs (before Gilda’s reformation, anyway) would fit better as neutral evil imo–the Diamond Dogs are just greedy while Gilda was a self-indulgent troublemaker.  
And Iron Will seems like the lawful neutral type to me. He’s not really evil, he’s just doing his job and getting a little bit too into it. His worst crime is simply not realizing that his methods don’t really work for people like Fluttershy.

@Turnways_Flip  
Primax 984.17 Alpha  
(I’m ashamed of myself for that one.)

@Turnways_Flip  
he doesn’t really do much.

@Turnways_Flip  

 
Most of them?

In what universe is Spike’s alignment nonevil

lol @ celestia isnt lawful good and gilda being chaotic evil

@YetAnotherBrony  
Man, I’ve been through this so many times. Iron Will may not have been a card-carrying villain per se, but he wasn’t the honest Abe that some people think. He upheld his guarantee because it would be downright fraudulent not to. People don’t deserve credit simply for avoiding getting into trouble with the law. He’s chaotic neutral at best. His obvious disregard for others could push him toward neutral evil with little effort.

I’d swap out Trixie with Tirek and then swap Tirek with Discord.

A lot of characters would be put into Lawful/Neutral/Chaotic Good, since FiM is that kind of show.
 
Iron Will isn’t Lawful Evil, he’s Lawful Neutral; when Fluttershy demanded a refund, Iron Will gave it to her, since he did say that satisfaction was guaranteed or your money back. He may not have liked it, but a deal’s a deal.
 
Suri is definitely Evil, but Lawful is pushing it a bit. I’d say Neutral; she cares for no one and will do anything to get to the top of her field, even extortion (towards Coco) and theft (of Rarity’s designs). She has no rule or law or personal code she’s unwilling to break, it’s all fair game.
 
Tirek straddles the line between Chaotic and Neutral Evil; he was your classic “destroy everything, rule over the remains” type of villain.

@Background Pony #161D  
That was me. Got logged out somehow.

@glockenspiel  
First off, an addition: Starlight Glimmer is textbook Lawful Evil. She believes in one guiding principle, and has strict rules in place to make sure that her twisted vision of “equality” is not compromised. Everypony stays in step, nopony asks questions, those who lose their way or fail to see the light must be “re-educated.”
 
Second, Sunset Shimmer could get put in Neutral Good as of Rainbow Rocks. Would having her in two different places with two different pictures be a good way to portray her allignment shift or would it just confuse people?

Let’s just scrap the thing and build it up from the ashes.

I would swap Gilda and Tirek.

@Background Pony #181A  
Didn’t see your comment before when I was posting mine, but I agree; he does fit more chaotic neutral.

@Revenant Wings  
Still disagree with notion regarding IW.

@Revenant Wings  
And place Rainbow Dash among Chaotic Good.  
And Iron Will among Lawful Neutral.  
Maybe even place Diamond and Silver Spoon in Lawful Evil.  
And maybe place Nightmare Moon more under Chaotic Evil.

I’d switch Gilda and Chrysalis.

@platypusmac  
More like chaotic neutral if anything. Not necessarily out to get you, but he doesn’t exactly care who gets trampled by his methods either.

Iron Will is pretty much Lawful Neutral… whenever he gives his word, he sticks to it no matter what.

@Aharon L’anglais
 
Post-reformation, yes. Before, he actively delighted in the corruption of the Mane 6. He didn’t just turn their Elements against them, he made them hate themselves and their friends, and he enjoyed it.

Isn’t Discord actually chaotic neutral? He seems like the kind of being who is beyond good and evil.

@YetAnotherBrony  
She’s good right where she’s at, in this little chart. She didn’t disregard the rules, she was following the spirit of the training that Spitfire explicitly endorsed. And she didn’t set out to endanger anyone, she was just trying to take everything to the extreme, which again, Spitfire encouraged by rewarding her for it. Dust was a jerk, but she was also very poorly trained.

@Background Pony #181A
 
Well, she’s Chaotic something. She spits in the face of Wonderbolts rules and regulations, pretty much saying “They apply only to mere mortal pegasi”.
 
People are leaning towards Evil, though, since Lightning Dust shows signs of sociopathy (she didn’t give two craps about endangering the lives of others).
