Harry Potter OC Critiques [PAUSED]

22 part 2: IvanTheGayest

Full Name: Decima Smith
(Decima means 'Tenth' in Latin and Smith is a very popular surname in both USA and UK)
Nicknames, Titles, etc: Doc (family and friends only), Heir of the House Smith, Encyclopedia of Weirdness (by Dexter and Sif)
General Appearance/Link to Photo: She has her father's blonde hair and her grandma's silvery-gray eyes, slim and toned body from all the gymnastics she does, and is ten centimeters taller than average which makes people think she's older.

[Gonna assume "average" is the average British height for women, in which case, congrats on reliably being able to reach things at the grocery store!]
Role in Book: Protagonist
General plot outline of the Book: Decima is the heir of the House Smith, one of the wealthiest and oldest families in the world. As she's about to get on the train, Harry Potter, her 'boyfriend' tells her he wants them to talk. Decima listens him and after he finishes breaking up with her, she punches him and breaks his nose.

[So far the list of people who have broken Harry Potter's nose on a train for annoying them is two names long, Draco Malfoy and Decima, which isn't an unreasonably long list, but which is maybe cause for some sort of broken-nose-on-train insurance.]

She runs out crying to the compartment she shares with her best friend. Swearing she's not going to date boys anymore, Decima falls into after-break-up mode. To cheer her up, Sif and Dexter, her brother, beg Calliope, her cousin, to put Decima's name in the Goblet and publicly humiliate Potter. Decima is chosen for a Champion along with Harry Potter, Fleur Delacour, and Viktor Krum.

[The plan seems like it's "beat Harry at the Triwizard Tournament and make him look like a nerd", but since almost nobody knew the goblet was rigged to choose Harry beforehand, I'm assuming it was actually just "cheer Decima up by getting her to win the Triwizard Tournament and make Harry look like an idiot for ending a relationship with such a cool kid" and the opportunity to beat Harry was just the world's most convenient evil plot to resurrect the Dark Lord.]

The Headmasters are enraged because there are not one, but two Hogwarts Champions and both of them are underage.

[How did Decima react? Actually, how did Harry react to both him and his newly ex-girlfriend winning the Death Game Lottery?]

The first task runs smoothly as her mother is a retired Dragonologist and so Decima picked up a trick or two,

[........This isn't necessarily relevant to her character, but a rundown of what she knows about dragons and how skilled she is at convincing them to let her steal their eggs would be a neat bonus.]

as for the Yule Ball, Decima went with Katarina Nikolajeva, a seventh year from Durmstrang which she befriended. With the second task coming up and Decima figuring out the egg the second she got it,

[Is this also a dragonologist thing re: her figuring out how it's different from a normal dragon egg and what those differences mean, or did she just drop it in the bathroom sink and pick up on context clues?]

she decided to use a strong Accio and dragged Sif out of the Black Lake with a stone Merman tied to her.

[Okay! So, disclaimers! This is from the Harry Potter wiki and, as such, could easily be contradicted by Something JK Rowling Said At Some Point, and I had to google what order the Harry Potter books go in, so my word isn't law, but there are a few things that would make this, if not impossible, difficult.

Thing one: accio doesn't work on people or anything else alive. Technically, you can summon a person's clothes, which will probably take them along for the ride, but since they travel Very Fast(wiki says "close to the speed of light"), it's likely to either tear their clothes and leave them behind except naked now or severely injure them from g-force.
