Keith (Infinity Apartment)
Keith was a normal human man from one of the universes where the Infinity Apartment existed. He was a neighbour of Jenny Everywhere, and refused to believe her about the Apartment's multi-dimensional nature until, after inviting him over, she opened the door again only for it to now exit to Jenny's front door in a universe populated by Dragons instead of Keith's own homeworld.
He later started hanging around in the Apartment frequently, now aware of its true nature. He once observed Jenny listening at the door of an as-yet-unclaimed room within the Apartment, with Jenny explaining more of the Apartment's functions to him in answer to his question about what she was doing.
When Jenny decided to take him, Ezri and Thuban to Club Jitsu, a ninja club, Keith wasted no time embarrassing himself, firstly by wondering where all the people were — needing to have it explained to him that, as a ninja club, most of the guests were remaining invisible or otherwise undetectable. After a few became visible nevertheless, he attempted to flirt with one ninja. This went so badly that she ended up hurling some throwing-stars at him.
For Halloween 2006, Keith dressed up as Harry Potter. (COMIC: Infinity Apartment)
