Prestina was a TV host turned assistant.
Prestina is a Caucasian female with blue eyes and long, wavy blonde hair. She wears a fancy outfit consisting of a pink jacket with jewels on the sleeves, pink pants, purple bowtie, and white boots. She also wears triangular earrings and a golden, jewel-covered tiara. She has a gold ring on each of her middle fingers.
Though she made it seem like to her coworkers and bosses that she wasn't upset about her show getting cancelled, in reality, she was actually furious about it—she vowed to shut down the studio so no one else could have a show on there if she couldn't.
She used to have a TV show on for the HBTV, but then it got cancelled and she became an assistant, claiming it wasn't a big deal for her, to which she was actually furious about.
A Pup Named Scooby-Doo
She dressed up as the Ghost of Al Cabone because she didn't want anyone to have a show at HBTV if she couldn't. To throw suspicion off herself, she created identities of Pop O'Conner and the Great Mel and made it look like each was the criminal. However, Velma and Daphne both realized her tricks as they noticed that both of her alternate identities wore the same rings as her.
