Catchphrase: "I'm the unluckiest bishoujo in the world!"
Cool Loser: This Loser Is You, but it takes the span of the whole series for Doremi to realize she has more True Companions than she thinks. Also, she gets along with all of her classmates, gets to take care of a cute baby, and gets to do magic... as pointed out by Mirei (of the fan site Candy Flower fame), what does she actually consider being lucky?
Balloon Belly: In an episode of Dokkan, Hazuki is forced to pretend she is Hana during a school trip due to Hana turning back to her original form and also has to eat her dinner alongside her own.
Parental Abandonment: Her parents are around and they do care for her, but her father is usually away and doesn't have a good relationship with her mother, who despite her good intentions sometimes seems to treat her more like a doll than a real child.
Ship Tease: She gets plenty of this with Masaru Yada to the extent that her friends act as Shippers On Deck regarding their "friendship", and they do eventually become an Official Couple in the Light Novel. The ship teasing could also constitute for some of the Les Yay shipping as well.
Spell My Name with an S: The subs call her Hadzuki. This is probably to emphasize that her name is spelled with the kana for "tsu." With the dakuten, it's pronounced "zu" anyway, but that spelling indicates how her name is written.
Static Character/Demoted to Extra: Especially later in the series, she and Aiko (to a lesser extent) are mostly ignored in favor of the other main characters. They also tend to not always be drawn as well.
Balloon Belly: In an episode of Dokkan, Aiko is forced to pretend she is Doremi due to Hana turning back into her original form and also has to eat Doremi's dinner alongside with hers.
Genre Savvy: She figured that something was fishy during one of the tests during Season 1 and gave falsified information to make the test easier for herself and her friends.
Spell My Name with an S: Aiko's last name is romanized differently on a bunch of official merchandise. Sharp merchandise lists it as "Senoo", Motto merchandise lists it as "Seno", and Dokkan merchandise lists it as "Senoh."
Demoted to Extra: In Dokkan, she had little to no Character Development (mainly because Motto gave her enough of it) or memorable moments, almost to the point where you could easily erase her from the script without affecting the main storyline.
Nonstandard Character Design: Like Onpu, Momoko does not have pupils. Similarly, her hair is less "bulby" and more "hairlike." Even Hazuki's hair (previously the most realistic) is usually shown more like a single, connected thing, but Momoko's hair looks more like it actually consists of individual strands. It's a bit jarring.
Character Development: She gains even more sympathetic development during Motto, where her self-centered and bratty behavior is revealed to be caused by her loneliness and insecurity. Momoko sees through this and becomes close friends with her, and also helps others to see Reika's true self.

Used to be human...
Accentuate the Negative: Majo Rika prefers to yell at the girls for what they did wrong, as opposed to praising them for anything done right, which she considers to be how they should do things by default.
Heel Face Turn: Eventually becomes drinking buddies with Majo Rika.
Honest John's Dealership: The magic items she sold while she was in control of the Mahou-Dou worked better than the items made by the girls but had serious side effects. Eventually came to bite her in the ass.
Honest John's Dealership: Has repeatedly tried to swindle the girls and Majo Rika by changing the prices of the goods she sometimes brings. Momoko sees through it by virtue of knowing the prices of the bakery items beforehand.
Leitmotif: She typically sings using a mystical voice when she shows up. The 4kids dub changed it to have an accordian and her singing isn't as nice.
Queen Incognito: She's been watching Doremi since she was five years old while in the guise of the school nurse.
The Reveal: Was really Yuki in disguise and had been watching Doremi since she was little.
Royals Who Actually Do Something: She has intervened on behalf of the girls and allowed them to pass exams where they would normally have failed. Near the end of Motto, she actually attempts to take Majo Tourbillon head on, despite knowing full well how powerful she is. And then during the beginning of Dokkan, she splits her pendant (weakening her powers in the process) so as to give Hana back her position of candidate for the next queen.
Butt Monkey: Whenever the FLAT 4 ultimately fail to bring Hana to the King of the Wizard World, they stick Hana on him and lure the Ojamajos into punishing him. Often with hilariousresults.
Would Hurt a Child: Turned all the Ojamajos into stone when he was first sent to capture Hana. Later, he even used the other babies as hostages to get away from the girls and force the older witches to comply.
Power-Up: The latter part is justified since he was under the influence of a magic-enhancing fruit.
Becoming the Mask: His affection towards Doremi was a ploy to get close enough to kidnap Hana at first. Eventually evolved into true affection and ultimately caused his Heel Face Turn.
Pride: Believed himself to be fully capable of doing anything with impressive skill, up to and including being an idol like Onpu. In fact, the main reason he kidnapped Hana during episode 41 of Sharp was to spite Onpu for telling him off.
Tooru: "You're a hundred years too young to be lecturing me!"
Laser-Guided Amnesia: Does this to her personal chef. Such magic is forbidden (as Onpu found out), yet she could pull it off without getting cursed into slumber.
Physical God: Is established to have the most powerful magic of any witch in the last 1000 years and has proven capable of beating Doremi, Hazuki, Aiko, and Onpu even when they used Royal Patraine.
Would Hurt a Child: At the end of Sharp, she casts a curse on Hana that nearly kills her.
During Motto, she casts another curse on Hana so as to hinder her growth. It fails near the end of Motto, prompting her to possess Momoko and bring Hana to her lair and kill her directly.
After Momoko snaps out of it, Majo Tourbillon attacks them directly with her magic.
