Mother Gothel in Tangled delights in piling on the fear and doubt to keep Rapunzel locked in her tower; she excuses her cruel words with assurances that she's "just teasing," criticizes and diminishes everything Rapunzel does, and casts herself as a victim whenever there's a confrontation between them. This is disturbingly similar to how emotionally abusive mothers behave in real life.
In the song "Mother Knows Best," notice how she trips Rapunzel, then tells her she's clumsy (along with the other Jerk Ass things she says), only for Rapunzel to run into her arms for comfort at the end of the song. What makes it worse is that Mother Gothel has been doing this to Rapunzel for the past eighteen years.
And this is all while Rapunzel is submissive to her, mind. At the end of the movie, when Rapunzel realizes that her beloved "mother" has actually been her jailer for eighteen years, Mother Gothel resorts to tying Rapunzel up to keep her in line. Then she kills Eugene and blames Rapunzel for his death.
The Lion King fans love to use this as their Freudian Excuse to sympathize with the bad guys. To justify Scar's actions, many fans give him an abusive or at least neglectful father. Considering that Scar's parents literally named him "trash", they may have a point. With Zira, itís even worse, varying from an absent father to one who purposefully tries to kill her. At the extreme opposite, the mothers tend to be extremely loving and devoted, yet powerless to end their child's suffering. In canon, there's a lot to suggest Zira herself did this to Nuka, Vitani, and Kovu, not least of all the way Kovu cowers in fear before her as both a child and an adult.
Not in the film itself, but heavily implied in the prequel novel to Snow White and the Seven Dwarfs, Fairest of All, that Queen Grimhilde's father caused her to be extremely insecure of her beauty by refusing to acknowledge it, which ultimately drove her insane especially after her sisters created a magic mirror by fusing her father's spirit with it and become the vain maniac that she was in the film.
This is all especially chilling because it's presumably what would have happened to the comics character Kon-El, Conner Kent, Post-Crisis Superboy, if Luthor's experiments had run a little more smoothly.
Lex: WHO'S YOUR DADDY?
The clone is all Knight Templar, so he goes rogue from Lex after that, and the first thing he does is dig the kryptonite bomb out of his skull with laser vision (incidentally, apparently the hemispheres of his brain aren't linked?), and then he saves Lois and Jimmy from Lex...and then rather horribly slaughters Lex's incipient clone army, ranging from oversized fetuses to nearly-mature specimens, with the ironic comment "Evil Supermen? Not on my watch!" The line of clones at the stage of development Conner was when he entered the scene were especially nasty to see die, although it was obvious as soon as they were introduced that they'd all have to be massacred somehow.
The incarnation of the Mouse Queen from The Nutcracker Prince is implied to be this around her son. Though she only has one son at the time, she still treats him like he is worthless as well as the fact she belittles his thoughts and slaps him with her glove when he doubts her spells would work.
In Cinderella III: A Twist in Time, Lady Tremaine is this to her own daughters as well as to Cinderella. It's revealed in an early scene that once Cinderella is out of the house, it's the daughters who are stuck with the slave-labor.
General Posada from The Book of Life, shows little respect for his daughter and views her as a bargaining chip for most of the story. Most apparent when he coerces her into accepting Joaquin's proposal just after she learns of Manolo's death, despite Joaquin's attempt to stop him. However, he seems to understand that his daughter did love Manolo, he just wants Joaquin to be there when Chakal arrives.
