Dragon (Infinity Apartment)
From Jenny Everywhere Wiki
A bipedal Dragon, from a universe where such things were commonplace, was a missionary. He once knocked on the door of his universe's version of Jenny Everywhere's Infinity Apartment, asking if she “would care to talk about our Lord”. Showing him this allowed Jenny to demonstrate her and her Apartment's multi-dimensional nature to the hitherto-skeptical Keith. (COMIC: Infinity Apartment)
