Otis is the most depraved and violent member of the Firefly family. He is a sadist who makes the freaks for Captain Spaulding's museum from the victims that he kills. On two occasions in both films, he wore his victims skin as a costume and often fights with Spaulding for control of the family. Although Otis is albino and clean shaven in the first film, Rob didn't think it would fit the style and realism of the sequel, which also saw Otis coming across as less manic and more calculating than he did earlier. In the second film Otis sports a beard, giving him more of a rugged and feral appearance. One feature in both films is Otis' taste for sexual violence: the implication that he is a rapist and necrophiliac with female victims of the first movie is confirmed in the sequel, where he also sexually assaults one of his hostages with a gun (a scene Moseley talks about on the DVD and is visibly horrified by).
