Here's a colored look that really highlights the differences between this version of Rutherford and the original.
The demonic essence in him didn't actually make him any more lusty or virile, it just warped his outward appearance to display more accurately what he always was on the inside.
He's still just as friendly, cuddly and kind as the original - but also more of a pervert and overtly conscious of his sexuality. If he likes you, expect to be invited into his hoard, where he puts his favorite fuckbuddies so they can buddy and fuck all the time.
