A hundred years ago, the British wizarding world saw the rise of a legend: Violander Vilant.
She was the guardian of Hogwarts Legacy, the inheritor of ancient magic, Hogwarts' youngest professor, the strongest dark witch in history, and a Dark Lord of her generation.
Everyone believed her future would shine as brightly as the ultimate Lumos, until she disappeared during the Battle of Hogwarts.
Some said she was killed in a sneak attack by a dark wizard. Others claimed she was abducted and her "Legacy" stolen. Still others said she was a coward who had hidden away to save her own life...
People in later generations came up with countless theories, but no one could have imagined that this legendary witch would turn into a little girl and transmigrate to Gotham in America a hundred years later. There, nine-year-old Jason Todd, AKA the future second Robin and Red Hood, took her home. Two years later, Batman took them both in.
Batman got two child laborers at once.
At first, Batman thought only one of the children he'd taken in was a mutant. That was until one of Violander's magical outbursts attracted the headmaster of a British school of magic.
Dumbledore: Long time no see, Professor. It feels like the great battle a hundred years ago was only yesterday. Perhaps you still remember me as your student?
Batman, Jason: ???
After learning Violander's true identity:
Batman, Jason: Wow.
Violander, who had regained her memories, AKA Bluebird, looked at the criminals running wild in Gotham, then at the noseless Dark Lord and his many Death Eaters in Britain. She slowly raised her wand, deciding to give these youngsters a little taste of magical shock and awe.
Batman: My love for you is hard to put into words. Even if the sky falls, I'll hold it up with my mouth.
Vilan (taking out shortbread laced with Veritaserum)
Dick: Oh, Blue, you're the only one who understands my taste.
Vilan: Right? Deep V-neck bodysuits are so cool!
Red Hood Jason: My hands are stained with the blood of evil. I'm the black sheep of the family.
Vilan: ? What made you think I've never killed anyone? I've killed more people than you've eaten spicy hot dogs!
Vilan: Voldemort, how many people has your Avada Kedavra killed?
Voldemort: At least a hundred or so.
Vilan: What about yesterday?
Voldemort: ???
Tim: Vid, I have a terminal illness where I'll die if I stop taking the stimulant potion.
Vilan: I think you'd be better off with Draught of Living Hell than a stimulant potion.
Damian: I'll kill you!
Vilan: Want to pet my kneazle and owl? Call me big sister and you can.
Damian: Not a chance. I'm Father's true-blooded son!
Vilan: What about a hippogriff, a unicorn, a kneazle, and a dragon? Oh, and I have a dragon egg too...
Damian: ...Big sister.
Superman (under mind control): ...
Vilan: ...
Vilan: Out-of-body experience.
