Ignorant of the Call: She had no idea she was a Namesake. Justified, as she's not really a Namesake and the Rippers have been keeping her from remembering her association with them.
Laser-Guided Amnesia: Given this by Nose to make her forget Oz, and later Trinket to make her forget rebelling against her father. Emma is heavily implied to have been getting this treatment for years to cover times when she's manifested Namesake powers, and thus also getting Fake Memories to patch these holes.
Missing Mom: Her mother appears briefly in a flashback, but it's unknown where she is in the present day or if she's still alive. It's also implied that Emma has been raising Elaine since Elaine was an infant, but the girls do have a father who's still alive though it turns out he's a Ripper and their mother has been confirmed to have been a Namesake too.
Historical Badass Upgrade / Beethoven Was an Alien Spy: The real Alice Liddell was, by all reliable sources, a fairly ordinary woman as an adult. Namesake's Alice fought Shadows and headed Calliope. Same with her eventual husband Reginald Hargreaves, who in real life was a cricket player but in the story is a weapons instructor for Calliope.
Ship Tease: With Reginald Hargreaves, which is a Foregone Conclusion since in both real life and the world of the comic she wound up marrying him, something that receives a Lampshade Hanging in The Rant for the comic that introduces him by saying you'd already know this if you read the "Calliope Handbook" extra or knew anything about the real Alice Liddell.
Parental Substitute: He sees Alice as his daughter-of-sorts, and tries to help her after she comes back from Wonderland.
The chief administrator of Calliope. She is very serious about making sure Namesake's powers don't run awry.
Fiery Redhead: She's quite a passionate leader, and not adverse to yelling at people in order to get things done. Perhaps justified in that, with her small size, she'd be quite easy to overlook otherwise.
Half-Human Hybrid: Somewhat. Upon first arriving in Wonderland she sustained serious injuries, and three Cheshire Cats decided to give her an extra life from each of them. This had the result of making her part-Wonderlander and allowing her to open portals at will.
Raised by Wolves: Starting at seven, anyway - the Cheshire cats took her in. She now has a huge Wonderland family of magic cats, and considers one of the original three her mother.
A member of the current Calliope and the Namesake for Wendy Darling from the story of Peter Pan.
Blond Guys Are Evil: His treatment of Emma and Nose and his end goal puts him firmly in evil territory.
Evil Uncle: What with the fact that he's the original Dorothy's uncle.
A Ripper who collected the shoes from 46. Of course, she wasn't the one who was sent to collect them, but she never said she was, did she? Also known by the nickname Fish.
A Ripper who is sent to collect the red shoes from 46. However, 72 got there first. Also known by the nickname Nose and the fake name Sahil, and was give the name Rumpelstiltskin by 1.
Addictive Magic: Nose seems to be kept on a leash by One using addictive magical substances. At the moment it's assumed this is because of his Artificial Human status - the other Rippers don't need it.
Affably Evil: Generally has a very pleasant and friendly demeanor, even when threatening a teenage girl. Readers frequently confess how difficult it is to hate him the way you want to hate a villain.
Ambiguously Brown: His exact ethnicity hasn't been specified on page, but the fact that he calls Emma "habibti", an Arabic term of endearment, implies he's from the Middle East. This was confirmed by Word of God.
Sympathetic Criminal: He's a protagonist, but he's committed a few crimes (including burning down an ancient forest). He's pretty casual about it, though, since losing most of his morals was another side-effect of removing his heart.
Agha: I know you've been through a lot, and you treated your sister pretty badly, but why do Ozites hate you?
Warrick: Oh, it's because I burned a few things. And stole a bunch of stuff, too.
Weaksauce Weakness: Being soaked in water will melt him, as the one weakness in his immortality spell. (Which is the same one the old Wicked Witch of the West used.)
The Tin Man's granddaughter and Warrick's twin sister. She is the Wicked Witch of the East.
Evil Twin: She and Warrick play with this trope. Turns out neither is evil.
Genki Girl: Turns out, she's normally just a sweet, energetic young woman.
Hoist By Her Own Petard: Her own spell backfires early on, and she accidentally turns herself into a purse and gets carried around for a good eight chapters. Except she could turn herself back at any time. She was just sulking.
Badass: Implied to have no formal military training, Jinjur is still an effective general and a strong fighter.
Determinator: After her husband and her farm get lost in the poppies, Jinjur decides to fix the entire situation herself by building and leading an army of like-minded people, and ends up playing a major role in the battle against Renge.
Warrick and Selva's mother, and the Tin Man's daughter. Ozma created her from a purple flower and a piece of the Tin Man's heart, and she has green and purple skin as a result. Her heart was broken at one point, which caused her to become the first Neutral Witch of the West.
From The Wizard of Oz ... sort of. A Namesake who comes to Oz every couple of years and becomes Ozma's companion. However, Ozma's healing spell doesn't work on her entirely, so while she never ages, she always dies.
A Wonderland card soldier - namely, the Five of Hearts - that Jack left to keep an eye on Ben and Elaine. Suddenly began speaking broken English and developing a more concrete personality once Elaine's Writer powers began emerging.
The Ageless: Technically paper, so he doesn't really have an age. He acts fairly childlike, but part of that is simple confusion and wonder at strange human things, like hair and sandwiches. The jury is out on why he's so short.
