Some new pics I doodled while reading
The Krill Report and this one guy's
beautifully fictional dossier of the Men in Black.




And a few notes, some taken directly from MiB lore webpages (written in italics) and some of my own ideas/twists written in standard type.
Some regard the mysterious Men in Black as "galactic enforcers." Their main goal seems to be to make sure that people who have seen something they are not supposed to have seen, or somehow acquired information that they are not supposed to know, keep their mouths shut.
No one really knows who the Men in Black really are. Some people think that they may be some sort of robot or android because of their erratic, robotic movements and strange voice.
They are erased men. Remade in reality's defense. Kept and redesigned in large tubes of amber liquid.
The Men in Black get their name from the fact that they like to black.
Black ties, white or black dress shirts, black shoes and black Fedora hats. In the case of my Custodians, white gloves as well.
They speak like a computer; dull and monotonous. Their favorite mode of transportation are big, black cars, such as Lincolns, Cadillacs, and Buicks. The cars normally have the the interior lit by a strange greenish or purple glow. Unusually insignia have been seen on the doors, and the license plates can never be traced or identified.
Very sensitive to bright light.
The Custodian cubes: Two kinds of cubes exist within Custodian disposal. Vertigo Cubes emit certain high frequency modulations to confuse and sometimes rewrite a target's brain patterns. This helps the Custodians cover their tracks and wipe away any evidence of their actions as well incapacitate victims with nausea.
Prescription Cubes serve as both snares and imprisonment devices. The cubes will expand to quickly swallow a victim within their obsidian black walls and then quickly shrink back to their original size of a 1 3/4" cube. The victim does not feel any difference in the cube's variant sizes. To them, they are occupying a 10 X 10 X 10 X 10' room with minimal light, no entrance or exits and strange patterns carved on the walls. Custodians can often times enter these rooms (the miniaturized cubes usually being carried by another Custodian in transport) to perform acts of interrogation or, if necessary, surgery. The walls of the room can slide out necessary arms for a black metalllic table, utilitarian seats, as well as various closets and compartments of necessary equipment a Custodian might need in the course of his interrogation. Only a Custodian can open or close a Prescription cube.
