Complete Monster/Magical Girl Lyrical Nanoha

"Fate: Mother, why would you do this to me?
 * Mad Scientist Precia Testarossa from the Magical Girl Lyrical Nanoha TV series. Her very first scene involves a horrific example of child abuse towards her Dark Magical Girl daughter Fate, . It should be mentioned that Fate didn't actually do anything wrong. She did exactly what her mother wanted and Precia still whipped her. She only gets worse from there. In fact, a decent part of the fandom.
 * Oh, and by the way, the spoilered Freudian Excuse was revealed by having her crush what little self-worth her nine-year old daughter had and laughing at her despair. That's right, instead of using the Freudian Excuse to make her sympathetic, the writers used it as a way to get the viewers to hate her more. And quite fitting, as it showcased how a woman who was kind at some point completely fell into madness and evil to a point beyond return.
 * Although she is much more sympathetic in the movie, which depicts her Start of Darkness in detail and gives her an Alas, Poor Villain moment. She's more of a Jerkass Woobie in that continuity. YMMV, though.
 * Think that's bad? In The Abridged Series by Raiki The Storm, it somehow managed to make her worse! Here's a little bit of dialogue between her and Fate:

Precia: Because you are a worthless piece of shit who could only give me four jewel seeds.

Fate: But mother, you only gave me two and a half episodes.

Precia: Fate, did you just talk back against me? (prepares the whip)

Fate: Oh F****! (gets whipped again)"


 * Or, in the original series, Precia reconsidered if she should've treated Fate like a real daughter. However, in the Abridged Series, it doesn't show her reconsidering. In fact, she calls her a failure before she died.
 * There is also Quattro from StrikerS, who is such a cruel Smug Snake -- much worse than the actual main villain of the season -- that you cannot help but hate the guts out of her and stand up and cheer when she finally gets the living crap blasted out of her in a Crowning Moment of Awesome by Nanoha herself. At least Precia was blatantly insane; Quattro is very much sane, she just enjoys hurting others. What would Quattro do with a helpless, terrified, and in very much pain six-year old girl who's crying for her mother? Torture her and tell her that said mother is an idiot, of course! Go. to. hell, Quattro.
 * Then there's Jail Scaglietti, Quattro's boss and a Mad Scientist far surpassing Precia, who doesn't make any pretenses to having a motive and proved himself to be utterly, disgustingly evil even before he used a six-year-old to power an Artifact of Doom and forced her to attack one of her two mommies, while he gave a brutal Hannibal Lecture to the other. Again, his WTF-pwnage by said second mommy after she recovered from his verbal beatdown was most wonderful to see.
 * And just like Precia, his Pet the Dog moments were surbverted in the end. He had 'em with his own custom-made daughters/minions, the Numbers...whom he'd impregnated with clones of himself as a potential escape route for when things went south. Eeeeeep.
 * Huckebeins Veyron and Cypha, courtesy of Force. Where do we begin? Veyron is introduced sitting around with dead nuns around him, heavily implying that he killed them. Cypha displays complete ignorance of the many people she's murdered, mocks Signum for bringing it up, then  . This might extend to the rest of the family, except Stella, because of her young age (but even she sees nothing wrong with all the killing), but these two are easily the most vile so far.
