Triana Orpheus is the daughter of Dr. Orpheus on The Venture Bros.  She's around the same age as the Venture Brothers, Hank and Dean, and Dean definitely crushes on her hardcore.  Triana dresses in goth clothing but actually is a pretty well adjusted kid considering the fact she's the daughter of a Necromancer.
