Badass Normal: He's managed to fight reasonably well against enemies clearly more dangerous than him with just his wits and stubbornness. In the preview comic he destroys an ancient temple. With his bare hands.
Butt Monkey: Life does not pull its punches when it comes to Mace. Still, he usually maintains a cheerful and optimistic disposition.
Guile Hero: Mace is crafty. He beats a Sandman with just a pillow and a blanket, then escapes Ravat using the pheromone-coated coins.
Conveniently an Orphan: Notably, the "convenient" aspect of this trope is played with, as while it gets rid of the characters of his parents, several of the other orphans, as well as the people responsible for running the orphanage, are characters that are heavily involved in the plot.
Lethal Harmless Powers: From what can be gathered, it seems that Lilith's Power involves moving life energy. Now, as is suitable to her personality, she can apparently use it to heal allies...Or, in its displayed usage, suck the life out of any living creatures nearby completely.
Or even technically living - ala the Nightmares.
She accidentally activated her Power on such a scale that, after being eaten by a giant Nightmare beast and activating her Power in self-defense, it was so far past death that its entrails fell out. By themselves. Either that, or its body was so fragile that it couldn't support Lilith's weight. Oh, and all of the plants for a few meters were dead, too. Also, to put the theory of how it might not have been able to support Lilith's weight in perspective: This beast was bigger than most of the trees nearby. And Lilith is a light-framed sixteen year-old girl.
Finally, if there was any doubt on the Nightmare being gone for good, Nightmares are basically just intelligent energy that have formed physical bodies. So, basically, that thing's entire existence was life energy; very evil life energy, but life energy nonetheless - And Lilith drains life energy. So...Yup.
Heroic Bastard: The bastard child of Viscount Callah and some unknown woman.
Knight Templar Little Sister: Do not ever try to hurt her big sister Lilith if you know what's good for you. Tinsel nearly learned this the hard way.
Little Miss Badass: The typical fashion choice helps. Matching an experienced Power user on the very first use of her own Power does, too. So does effortlessly beating two guards, one of whom was MASSIVE, with casual ease.
Teen Genius: She's shown to be very intelligent despite her disregard for formal education.
Tsundere: Kind of a less-extreme version; she's usually non-combative, just a little bit off-putting...But she deeply loves her sister, Lilith, because Lilith was essentially the only true friend she's ever had.
It was to save Lilith that Namah's Power awakened.
Whip It Good: Taken Up to Eleven levels with her Ether Tendrils. As in, energy whips that can be extended from each fingertip, and apparently have no actual set limit to their reach. Oh, and if needed, they can cut and stab too.
An anti-social boy with violent tendencies who attends Mace's school.
Dark and Troubled Past: The reason we haven't seen his childhood in Prelude yet. It's apparently nowhere near as lighthearted as the orphans' or the Callahs'.
He seems to be on familiar terms with a violent street gang.
Jerkass: He had no problem pummeling Mace after he was nicely asked to move away from Mace's locker.
Playing with Fire: From what's been explained/shown on the website and in a free comic, Bast's Power is Heat Manipulation.
The Sociopath: Bast possesses close to, maybe more than half of the listed traits. Or at least, he's shown such attributes most prominently in his fight with Mace.
Tranquil Fury: Apparently his default mode; however, this is his normal mood, to some degree. As in, not how he's prone to react when he's actually angered. Instead, we get...
Unstoppable Rage: It's easy to blow his fuse. As in, when he was blocking Mace's locker and ignored requests to move, Mace grabbed his scarf and pulled him down to get his attention. Bast's inevitable response was to punch him in the face. Throwing him into a locker. On the other side of the hallway...And after that, he went to beat Mace up more.
The alcoholic proprietor of Mace's orphanage.
Abusive Parents: Hoo boy. It would be too glorifying to Grunn to list all of his accomplishments in this field, but his character descriptions aren't lying when they say roughly that caring for orphans is "the very task he's least suited for."
However, he at least seemed concerned for the kids, enough to not want to tell them the full situation because it would freak them out. He might have accidentally drank himself all the way around to nice for a second.
Plus, Igrath probably wouldn't even consider letting Grunn have any part in his operations if he didn't have something to redeem himself. I mean, Scinter makes jokes about shooting kids to 'reduce the surplus population', but Grunn actually thinks about shooting kids.
It probably counts as a Charles Atlas Superpower that he can remain aware enough of his surroundings without his sight to prevent from seriously hurting others on accident, considering his size, wingspan, and large claws. Being a blind, eleven-foot-three griffon man is complicated.
Volume 3 includes a scene where he starts bumping into things because they'd been rearranged, meaning he couldn't avoid them based on memory. And he knocks some stuff over unfurling his wings in excitement. So he has his limits.
Eyes Always Shut: In the present day. A magazine clipping at the end of V3 shows what his eyes looked like prior to his blinding.
Gentle Giant: He has to be, because with his claws and blindness and sheer size, not noticing somebody and making a wrong move could...Well, he might have another person to be blind with. ... Or, possibly crush them by accident.
The mastermind of the largest black market trade operation in all of Anduruna.
Bad Ass: He had to be told that he had a knife stabbed into his knee.
Scinter: Hm? Oh, right. * CHNK*
Mad Scientist: It would be impossible to tell from just the graphic novels, but from reading the info on the site, it becomes clear: Scinter was the one who originally conceived Anduruna's teleportation system, after he was able to catch the elusive and dangerous teleporting squid that power it. Scientist. However, the Andurunan government arrested him for catching the squids and inventing without the government's approval, which would have probably taken years, and he was thrown in prison. Oh, and they went ahead and used his plans to build the Telepad system. Perhaps not quite mad as in insane, but definitely 'angry.
That actually leads to a bit of Fridge Brilliance - Since he originally designed the telepad, and he and Igrath have telepads in their safehouse, an old fortress in the mountains, and the orphanage...It seems Lilith was right to be suspect of Igrath.
Lilith: He doesn't even know how to use an info-scroll. (Which are basically the rough equivalent of cell-phones.)
Not Quite Dead: Scinter was believed to be assassinated long before the story - But rumors still circulated that he hadn't died...And seeing as how he's present in the story, and has a conspicuous neckbrace...Yeah...
Heart Is an Awesome Power: The ability to change colors? That's pretty lame as far as powers go. But then they go and use it as a way to disguise themselves practically right in front of a platoon of enemy soldiers.
Meaningful Name: The Indigos' real names are Indi and Digo Marrallang. They both have an immense crush on Igrath. In Australian Aboriginal mythology, the Mar'rallang sisters both married the same man.
Wonder Twin Powers: They can freely change their colors and patterns, even hair color, with one condition - They have to be the opposite of each other. Ex.: If one's yellow with orange stripes, the other has to be orange with yellow stripes.
Victoria's Secret Compartment: One of them stores a communicator in her cleavage, to put it bluntly. And the communicator has a way of alerting its owner to messages while it's… In storage: Vibrating. It's quite startling when she gets a message right in the middle of an argument with her sister.
A tomboyish weapons expert who works with Igrath and Scinter.
Action Girl: She beats the snot out of her fellow orphans in Prelude pillow fights. In the novels she is a member of the resistance.
Psycho for Hire: Ravat and Tinsel's relationship seems to roughly be that Ravat is sent to kill whoever Tinsel designates — which he's all too happy to do — in exchange for what appears to be monetary payment. Although Ravat's clearly stated that he'd be happy to take other forms of payment, too.
Break the Cutie: Tinsel seems to put tormenting Wisp above any other goals at the moment Wisp is present or a good plan comes to her. From what's been seen of their interactions, Tinsel lies continuously to Wisp and will say anything to sadden/scare her.
But this particular Cutie seems to have already been Broken somewhere in the past.
As seen where Wisp stopped to answer Namah's question of why she was attacking the main characters - Right in the middle of fighting her.
Wisp: Well, since you bring it up, it's a long story, actually…
Kaleidoscope Eyes: Wisp very nearly takes it Up to Eleven, as practically every major emotion for her has different-colored eyes. Considering the severity of Wisp's mood swings, it's very hard to tell what color her eyes are normally supposed to be - Which would be not-so-nasty, orange Hellish Pupils. These are what seem to be definitive for her:
Bigger Bad: Well, for the time being, it seems... From the first few pages of Volume Three, it seems that, despite being summoned properly, he has yet to return to full power - After a battle with Nabonidus in which there were many borderline-cataclysmic explosions, the two "agreed to an accord". So, that probably just means that Void is going to sit back and return to full power while Nabonidus heads the Nightmare forces in his place.
