Even Bad Men Love Their Mamas: He fights the hardest against the Hollow that killed his mother, and is clearly very distraught when mourning her. It's the only time Astaroth has no clue how to interact with him.
Even Evil Has Standards: Is disgusted by his dad's hypocrisy and is terrified when he learns that he ate and killed a living soul by accident.
OOC Is Serious Business: Before he bursts out the story of his mother's death to Botan, he politely asks her if he can have the next day off.
Would Hurt a Child: He has no problem threatening the random kid he saved in order to blackmail Botan.
Despair Event Horizon: Appears to have crossed this after her execution is announced. Or maybe she just learned to stop responding to Renji.
Ethical Slut: She apparently either is this, or used to be one when in school. She's the Token Good member of the three main characters, apparently has some really wild sex stories, and is only known to the filler ninja because he heard of her reputation while in the Academy. One of which earned her the name RukiAAAAAHH!! which she apparently takes pride in, as she told the story to Ichigo.
Pass the Popcorn: He and Xaphan pull up a tub of popcorn to watch Ichigo and Renji battle. They treat the entire thing like a competition between themselves.
Psychotic Smirk: Usually when he smiles ominous music plays, implying that he has one on. Because he's, well, a butterfly, it's kind of hard to tell due to the way he's animated. The most notable exception is when he possesses Ichigo for a day.
Urahara: I have a little girl in the basement being guarded by a little boy.
Even Evil Has Standards: Considering he isn't remotely phased by his friend and employee dying in front of him, holding a little girl for ransom, and refuses to let Mexicans in his store; he was rather disturbed when Ichigo thought he wanted to kill a woman he'd knocked up.
Only Sane Man: When Chizuru makes a move on her, her response is to confirm that Chizuru is a lesbian and then to say that it doesn't need to be addressed any further. When the (female) Hollow shows up and refers to herself as a "malevolent spirit of homosexuality" Orihime's first solution is to let the Hollow and Chizuru go off together. All throughout her battle with the Hollow, she points out its stupidity. The one time she doesn't bother is when she's learning how to use her powers and the Hollow does nothing to attack her.
Dark Magical Angsty Teen: Parodied. He's got magic powers, he's very lonely, and everything he does is because he doesn't have friends, someone denied him friendship, or because he thinks someone wants to be his friend. Urahara uses this to recruit him, knowing that Uryu will do anything for social interaction. All of which is played for laughs.
Evil Laugh: Gives one when he hears Ichigo wants his help.
No Sense of Humor: Compared to the other characters, he often deals with infuriating situations by getting mad and blowing up at whoever mad him angry.
Samus Is a Girl: Gender-inverted, whenever he tells people that he's a witch, their first question is "You're a girl?"
Abusive Parent: It's his entire character. Until Astaroth beats it out of him, then he's too scared to hurt Ichigo.
Death by Adaptation: Ichigo kills him in shock, and everything his canon counterpart did is done by Astaroth.
Ethnic Menial Labor: Invoked. He has to do all the physical labor, because he's a black guy. He knows this, and interrupts Botan to point it out.
Fate Worse than Death: Is doomed to an eternity of darkness inside Ichigo's room, rather then being allowed to pass on. Despite the fact that Ichigo himself is a Psychopomp.
Small Annoying Creature: He's so annoying the people who's job it is to help him refuse to do so because he's just that annoying.
Obfuscating Stupidity: Whenever she's invilved in a Hollow attack, since nobody bothered to erase her memories or explain what's going on, she ended up with some crazyideas about who the enemy is.
Too Dumb to Live: Seriously, her plan to fight "the air" is to take Karate. And her plan for defeating oxygen is to turn it into carbon dioxide.
Butt Monkey: Let's see, he gets mocked in every scene he's in, his voice sounds like he breathes nothing but helium, and nobody even bats an eye when he kills himself.
Karin and Yuzu Kurosaki
Obfuscating Stupidity: Both of them. Karin gets grabbed by a Hollow and her complaint is that she's in a situation she's not accustomed to. The Yuzu, much like Tatsuki, thinks the air is sticky when she's being picked up by a Hollow.
Head Captain Yamamoto/Big Yama
Cloud Cuckoo Lander: In the poem/letter sent to Rukia, he basically tells her the reason his using said method of execution is because he's never seen it and is excited by it. He also buys a staff.........that turns into a gold, gem-encrusted rod......that has Twilight Sparkle on it.
Pointy-Haired Boss: In terms of actually doing his job, he usually interferes in the other captains daily lives and does stupid things that have no meaning.
Benevolent Boss: Compared to Yamamoto, he at least put up with Renji's antics and prevents himself from hurting the idiot.
Byakuya: Calm down, Byakuya. Renji must really need a win right now.
Took a Level in Jerkass: Somehow simultaneous with his behavior towards Renji, it's obvious that Byakuya honestly does not give a shit about his sister. When he announces her execution, what gets him most upset is the order for him to pick up a milkshake for the head captain.
