Chronic Hero Syndrome: Leaps to the aid of anyone in trouble, be it her friends, a new transfer student she's never met before, or Amy the cat. Prior to becoming a magical girl, however, she doesn't have the self-confidence to follow through on this all the time.
In Mami's route, Madoka can even wind up coming on too strong and making Homura uncomfortable with all the attention she's getting.
Combat Medic: She was known as archer, but a third of her active skills are healing techniques. She can even heal murky Soul Gems!
Crutch Character: Employed rather interestingly. As long as she's been properly raisednote (given equal status doping and taught skills rather than ignored in favor of other party members), Madoka can eat Walpurgis Night and its familiars for breakfast. But because the story eventually progresses to Homura's wanting to keep her from contracting, Madoka isn't an available party member in the later routes, where the Walpurgis battle actually matters.
Only Sane Man: In the bonus route, as all the other girls eventually get drawn into Homura's wacky plans.
Plucky Girl: Especially in early timelines, where she quickly bounces back from revelations of the true nature of magical girls and refuses to give in to despair.
A Taste of Power: In Madoka's (tutorial) route that follows the anime closely, Homura is at level 25 at the start of Charlotte's fight. Compared to Mami's level 10 (and she can be considered a veteran) and Sayaka's level 1, Fridge Brilliance plays here when you remember just how much her accumulating experience from her time-loops affects this.
Didn't Think This Through: In the bonus route, she spends so much time and effort making Mami, Sayaka, and Kyouko happy individually that there's no time for the five girls to learn to work together before fighting Walpurgis Night. When the others turn to her for advice, Homura gives up and resets the timeline right away.
Died in Your Arms Tonight: If she tries to solo Walpurgisnacht and wins, she still ends up dying in Madoka's arms. Finally in peace knowing that Madoka will never make a contract and with the Witch finally gone, she moves on without succumbing to her despair.
Part of the name of flower (Higan) is also a homophone for nirvana, contrasting with the type of witch hers is (Shigan, the Mortal World).
The Gadfly: Bonus route, justified as she acts the way that she never was before to see a different outcome.
Homura:(In overly enthusiastic tone) Even though you're a magical girl, you've got the artistic sense to name your finishing move 'Tiro Finale'. A finishing move!! With a name!! And that name is 'Tiro Finale'!! How amazing!!
Always Someone Better: She realizes that she's the weakest girl in the Mitakihara group, which really does wonders to her self-esteem. Kyubey says that she spends ten times the amount of magic in her familiar hunting than Kyouko's brutal frustration-fending massacre of the same familiars. When Mami gets her head chomped off, Sayaka thinks that she's not worthy to be a magical girl and throws her Soul Gem inside Charlotte's barrier, triggering the already elaborated event of And I Must Scream above.
Butt Monkey: All the girls have at least one opportunity to become witches somewhere or other in the story, but Sayaka has more than anyone else. In her own route, there are two points at which she might turn into a witch, and both involve her accidentally traumatizing Kyousuke into a Freak Out and calling her a monster.
Cat Fight: With Hitomi in the bonus route. More of a screaming match, to be precise, but Hitomi still slaps Sayaka.
Clingy Jealous Girl: In her own route, she's not at all pleased to have to share Madoka with Mami and Homura, especially since Madoka has to go on witch patrol and can't hang out with her as much.
Oblivious to Love: Though she's usually the victim of this from Kyousuke, in the Tea Party ending, Sayaka acts this way towards Kyouko, not understanding why her effusive praise of Mami's cleanliness hurts Kyouko's feelings.
Butt Monkey: Dies or at least has a chance of dying in every route but the bonus one.
Clingy Jealous Girl / Green-Eyed Monster: In her own route, she becomes insecure in her friendship with Madoka and resentful towards Homura when the latter enters the picture. Depending on the player, Mami can either discuss her feelings with Madoka or isolate herself and become more and more miserable to the point where she breaks down after fighting Gisela alone and becomes a witch.
Despair Event Horizon: Similar to Sayaka's in that she's found by someone, show her tainted Soul Gem and has a few last words, but for different reasons and what turns her into Candeloro in her route:
Survivor Guilt: She really takes the fact that she could have saved her parents along with herself, but didn't, hard. When she runs away and lets a child get eaten by Gisela, the guilt becomes twofold. Later, depending on the Road Cone, she can save the child's mother, thinking that she can finally atone. But the mother is already suicidal to begin with because her child is dead, and demands to know why Mami didn't let her die. This is one of the factors that contributes to Mami turning into a witch.
Team Mom: Particularly in Sayaka's route, where she has to temporarily play peacekeeper between Sayaka and Madoka, then between Sayaka and Kyouko.
Whip It Good: Mami's weapon is actually her ribbons, used in this manner. But until her encounter with Gisela, she decides that she can't fight in close range, making her muskets from the ribbons as her primary weapon.
"She's the only hope I had left."
A-Cup Angst: When Sayaka makes her try on Mami's school uniform, she's rather put out by Sayaka's comments that it's loose in the chest.
Be Careful What You Wish For: It turns out to be even worse than what the anime showed us. After learning about her wish, Kyoko's father makes an intentionally ridiculous sermon where he claims God doesn't exist and despair is the only thing that guides humans. Kyoko and her father are horrified when the parishioners start agreeing with it. It soon becomes clear that Kyoko's father has a Compelling Voice, which drives him over the Despair Event Horizon because he thinks it makes him like the devil. He then calls Kyoko a witch and all the parishioners join in.
Due to the Dead: She makes Mami a grave in the day 10 of her route and gives it some flowers and teddy bear from the game center she often plays in. It's very simple, but the effect is powerful.
Fire-Forged Friends: With Sayaka in Sayaka's route, eventually, if Sayaka doesn't wind up turning into a witch first.
Out of Focus: In Homura and Bonus Route, mostly because she's no longer has reservation of not shooting him in public after exposing his eating his own corpses habit.
All There in the Manual: Albertine, a witch first mentioned on the anime's website, is revealed in the game. Gisela might also count, given that she is only seen for about two seconds in the anime during a flashback sequence.
Canon Foreigner: The game has several original witches, such as Candeloro and Ophelia the witch forms of Mami and Kyoko, respectively. There's a also a witch that has Kyubey's head and uses giant stuffed Kyubeys as familiars, and another witch that resembles a Brain in a Jar and is said to be from another planet.
Creepy Doll: Albertine. Candeloro's familiars which resemble Madoka and Kyoko as maids may also count.
