D-19 (1996-2009) was a mutated Dean clone that was "aborted" by Dr. Venture but some how managed to survive. He lived in the The Venture Compound 's attic for years alone and was desperate to be a "real Dean". He plastered the attic walls with photos of Dean, stole one of Dean's stuffed animals, and collected dead Dean clones to make a poorly-fitting suit out of their skin. He often had hallucinations of Dr. Venture talking to him and telling him what to do. Ultimately, he attempted to kill Dean for his face to complete his skin suit.
