Lorelei Leigh

Proffesor Lorelei Leigh is a member of the "Ghost Scene Investigation" program. Judging by both her looks, and smarts, she's an equivilent combanation of both Velma Dinkley and Daphne Blake. She is only seen in the video game, Scooby-Doo! Who's Watching Who?

Physical Appearance
Lorelei basically shares Daphne's looks, but her hair is shorter (and a different color.) She has short, blonde hair, and wears glasses, like Velma. She also wears a white shirt, black coat and skirt, and black boots.

Scooby-Doo! Who's Watching Who?
Prof. Lorelei Leigh was the only girl in the GSI group, she's a combination of both Velma's smarts, and Daphne's looks. When Mystery Inc. and the GSI were working together (and fighting), she mostly fought with Daphne and Velma.

When she and her colleagues reappeared in the game's "final area," she and the GSI were suspects for The Ghost Hunter Haunter.
