Do you think you wished you could have fought her? I mean, you fight her cat in Ven's story, she has enough darkness to create two powerful Unversed for Terra and Aqua to fight. But the way the Cursed Coach gets rid of her was a little harsh. But obviously, she won't have a reason to join the villains in the first game. Lady Tremaine is just so evil, she hates her stepdaughter's charm and beauty, she tried to stop Anastasia from being with her true love, and in the third movie (which I did watch and liked it because Cinderella actually did something on her own), she believed her misery was caused by Cinderella fitting the slipper. I would have loved to hit her with a Keyblade.
