Amelia Wil Tesla Seyruun is the daughter of Crown Prince Philionel El De Seyruun, and the sister of Naga the White Serpent. She lives for the love of justice, and is very zany, quirky and hyperactive! She is often seen given justice crys and speeches. She's also very confident, and is one of the more intelligent members of Lina's crew.
When Amelia first appeared in Slayers, she was voiced by Joani Baker for episodes 11-13. When the dub was put on hiatus for a year to evaluate sales, Joani basically moved on with her career, and stopped showing up at auditions, and thus, Central Park Media, and Taj Productions lost all contact with her, and the role was recast.
Joani's replacement, for pretty much all of the rest of the Slayers franchise was Veronica Taylor of Pokemon fame (only this was before Pokemon). Veronica reprised her role in Slayers Revolution/Evolution-R.
However, Veronica was unavailable for the recording of the Slayers Premium movie (Amelia's only movie appearance), which was being dubbed by ADV Films. Luci Christian filled in for her instead.
