You didn't miss it...at least I think you didn't...
...and I hope soon because it bugs me that nobody is curious where the furry little critters who look like Nightcrawler, have similar powers, and are named "Bamfs" come from.
They've kind of got more pressing matters to deal with.
But Bamfs are not new.
In Uncanny X-Men #153, Kitty Pryde tells a fairy tale to six-year old Illyana Rasputin, which includes a race of creatures called "Bamfs." Bamfs appear to be small versions of Nightcrawler, who even wear a costume identical to his classic costume. One of the Bamfs enters the story after catching sight of Pirate Kitty, on whom he developed an instant crush, when she and her entourage landed on Bamf Island. He subsequently joins her team and aids in taking down Princess Jean (the fairy tale equivalent of Jean Grey), aka Dark Phoenix.
Later, in the first Nightcrawler limited series in 1985, Nightcrawler is sent to another universe that is identical to Kitty's fairy tale, where he encounters the Bamfs, including the heroic Bamf from Kitty's tale. Nightcrawler discovers that female Bamfs differ from the males in that they are taller, resembling female versions of himself. The male Bamfs are lecherous, flirtatious and skirt-chasing, making them rather tiring company in the presence of attractive females.
Even before Kitty's fairy tale, plush versions of Nightcrawler, also called "Bamfs", had appeared in many issues of Uncanny X-Men. Kitty Pryde, Illyana Rasputin, Jubilation Lee and Amanda Sefton, among others, have been shown owning Bamf dolls.[volume & issue needed] In the series Exiles, a stuffed Bamf is seen in the bedroom of Nocturne, the child of Nightcrawler and the Scarlet Witch from another reality.[volume & issue needed]
