Amazon Chaser: He has a crush on General Lydia and wants to become a hero partly so he can be a Battle Couple with her. note the other part of his reason is to emulate his mother.
Expy: He's Ben 2.0; a supporting protagonist without combat skills that follows the heroes and gets an Eleventh Hour Superpower. The key difference between them is Benji doesn't say Shout Outs to real world products.
God-Mode Sue: In-universe example. He has a dream where he defeats an evil overlord and his army simultanesouly with Pure Awesomeness. He is nowhere near this when he's awake. Not even when he awakens his dragokin powers.
Guile Hero: Downplayed as he's too much of an Idiot Hero to make proper use of it but he shows potential:
Zarracka is impressed by the deviousness of his plan to escape a city.
He wins his fight with Kthonia by outsmarting her instead of overpowering her.
The Hero: What he wants to be. The prologue is a dream of his where he saves a village from an evil overlord.
Jumped at the Call: Exaggerated; he didn't get a call in the first place but he still wants to be a hero.
Kid Hero: Tries again and again to be this but constantly fails until the final act.
Lamarck Was Right: Everyone thinks he will inherit his mother's power but he's a normal human Until the climax.
The Load: He's useless in battle and has nothing to contributed outside of battle.
The Mill Stone: His over-eagerness combined with his incompetence cause a great deal of trouble.
Dark and Troubled Past: All of them have one that explains why they feel the way they do; the three girls were kidnapped and raped by truly evil men and the guy had his hands cut off and left for dead for deserting the Leondian army. All of them function as a Freudian Excuse except for the last one. The only thing his past does is make him angst about how he can no longer truly embrace his precious little sister.
Evil Plan: Awaken Kthonia and wipe out every last man on Draconica because men (except Ravage) are evil.
Females Are More Innocent: The only reason the three women want to wipe out all the men in the world is because they were horrifically abused by men and so they think all of them are evil. Even Ktonia herself fits this trope; Jihadain, her daughter, attacks Daniar, Kalak's wife, and is killed by him for it. Kthonia watches this happen and thinks everything is Kalak's fault.
I Am Not Left-Handed: Ravage has a Super Mode that makes him bigger and stronger and tougher; he uses it when Finn gains the upper hand in their fight.
Mind Rape: Abyss uses Psychic Powers to invade her target's mind, find their worst memory, and uses it to break them psychologically.
Bigger Bad: She is more poweful than all of the knights put together but she is locked away and unaware of their plans to free her. In fact, she's surprised and tries to talk Jihadain out of it until Kalak kills her and she freaks out.
Character Death: She is the first villain that is deliberately killed by the heroes.
Gendercide: Like her knights, she wants to kill all men.
Omnicidal Maniac: After Daniar points out that women are not morally superior to men, she decides to kill everyone.
Happily Married: She was happy with her husband before she was burned at the stake.
Heel-Face Revolving Door: First she was evil and then she turned good because of her lover and then bad again because of Kalak killing Sali-ka and then pretended to reform to avoid dying again before she was finally killed.
The Juggernaut: Her fight scene is, in a nutshell, her walking down the street while the heroes throw themselves at her in pointless attempts to stop or harm her.
Mama Bear: She was harmless until Kalak killed her daughter, Sali-ka.
Not Using the Z Word: Being a life form that died and then cam back to life as something else, she's technically a zombie but no one uses that word.
Sealed Evil in a Can: Trapped within her heart which was hidden in a place no one would think to look for it.
Man In Shadow
The Chessmaster: Rana didn't send a distress message to Brittania; this guy did. He orcastrated the events in Drewghaven to draw Daniar's attention away from her castle and Erowin's grave. The final scene of the book shows the youngest dragokin's corpse was his goal all along.
Faux Affably Evil: He's casual and affable at all times; even when threatening to rape the person he's talking to.
Handicapped Badass: Deconstructed. He's a big and strong guy but with a bum leg there's little he can do to stop Mordak and Zarracka from destroying Final Shield. Then again, the legs of his Mini Mecha work fine.
Mean Boss: Rufus Shouts abuse at his goblin employees because they're stupid and get on his nerves.
Translator Buddy: The goblins never speak like the other characters and yet Rufus can understand them.
New Old Flame: He had a close relationship with Daniar in the past but she never mentioned him; not even when she started a relationship with Kalak.
Reasonable Authority Figure: He does an admirable job managing his city. To demonstrate: he refuses to let the civilians of others cities die or mutate but can't take in too many or they'll all starve. Also, he insists on protocol when letting anyone in or out of Final Shield.
You Shall Not Pass: Stands in Jihadain's way during the climax and is little more than road bumb to her.
