"Those old fools who run those nations... What do they know about rule? They simply think that if they sit there and collect taxes, they are a good ruler? Hah! When we take over, I will show them what a true ruler is capable of..."
Arson, Murder, and Jaywalking - Darken asks Thereme for tips on finding the artifact in Jopo, how to contact him again once the task is accomplished and finally for some food.
Ax-Crazy - To say that Kenneth has completely lost it would be an understatement.
Berserk Button - Narome has two. Don't put pressure on his punctors, and don't threaten Kea. Though not exactly a Berserk Button, going too long without life energy will have the same effect as the first one.
The Mayor has a pretty serious case of this too, sometimes.
Curbstomp Battle - The battle between Exa and Kenneth, which mostly consisted of Kenneth taking a lot of damage, and not being able to retaliate.
Dark and Troubled Past - Narome has been forced to murder to survive for a good deal of his life. Mika's lived many years with memories of the tragedy where his entire crew, save for him, died. Kenneth was abused by his parents and lived a tough life of crime. Thereme's parents were killed by political spies. Exa lived for years without her father and when she did meet him, he turned out to be a criminal who she drove away, causing everyone to turn against her. Drey had an abusive father.
Dark Is Not Evil - Despite Ewyn being a Dark Mage, he really isn't that bad of a person.
On a similar note, Cynder Janice is a necromancer, but opposed to Darath and on the heroes side.
Divergent Character Evolution - Assassins Drey Wilkins and Vincent Bodrovi start off as basically the same guy. As the RP goes on, Vincent is gradually given his own personality. And then he died.
Enemy Mine - Mika teams up with Darken, the guy who tore open a hole in his ship, captured his friend then attacked Mika when he came to get her back. Guess you have to do these things when a big dragon suddenly flies at you. Naturally, they can't even agree on how to deal with the dragon and still fight.
Even Evil Has Standards - Exa is disgusted when she learns that Thereme killed off most of Sabolin to win the war, since she only kills people who she thinks deserve it(even if she tends to make these decisions quickly).
Near Death Experience - Narome is nearly killed when a prison guard shoots him in the chest. Luckily, he survives via the combadge tucked into his gi. Narome leaves with newfound determination to put things right with Mika and Kea.
No One Should Survive That - Drey falls out of the airship at the end of his fight with Narome but through sheer luck, is able to swing to the other side of the ship on a rope.
Only Sane Man - Vincent is a minor example of this. While other people act wacky and strange he can only scratch his head and sigh. While he may not be a classic example, it does seem to fit.
Omnicidal Maniac - Atlantis the Bloodwater. Luckily for the rest of us, he's still working on it.
Villain Protagonist - Minoru Akihiro, but he only qualifies if you consider him The Hero and subscribe to his Alternate Character Interpretation. Otherwise, if you count every character as the protagonist of their own story, then any of the evil-aligned characters fit this.
Lamont, without a doubt. He is busy conquering a country, but at the rate things are going, it seems likely that he will be at war with Darath before long.
Well-Intentioned Extremist - Darlan spends most of his time conning people into extremely dangerous experiments. He wants to make an invention that will eventually help the world, but his methods are decidedly questionable.
Wrong Genre Savvy - Alexis Lockswell seems to think that she's in a very idealistic story with Black and White Morality in which Darath is a heroic nation and the other nations are evil, and all necromancers and demons are evil. She's wrong.
You Can't Go Home Again - Tragically so for Mika, who has been living in the nations for 7 years, since the Defiant could no longer travel in space.
You Have Failed Me - Thereme's jester and interrogater/torturer are killed for not doing their jobs well.
