Major Story Arcs
The Painting That Ate Paris
The Fog is sent to Japan along with Sleepwalk to retrieve the Quiz. Returning to Mr Nobody, he joins the team in stealing the Painting That Ate Paris. After the Brotherhood traps Paris and themselves in the painting, he confronts and manages to absorb Crazy Jane. Her split personalities destabilize his internal structure, however, and he is forced to regurgitate her. After the Brotherhood and the Doom Patrol successfully defeat the Fifth Horseman of the Apocalypse, he elects to remain inside the painting alongside the other Brotherhood members.
Powers and Abilities
Fogg is able to transform himself into a cloud of smoke which can absorb any humans that come into contact with it. Their minds remain forever trapped inside him, and are able to interrupt his speech even when he is in human form. He appears to have an unlimited capacity for humans he can absorb. It is unclear if he can gain powers through absorption, or if he can absorb non-humans.
