Sleet is a pale man with black, slicked back, graying hair. He has light blue eyes and wears glasses. Sleet wears a suit with a gray-blue vest and a dark blue tie.
Sleet appears to be a professional man who keeps Atlas' concerns in mind. He is also shown to be frustrated with James Ironwood's practices as General and Headmaster of Atlas Academy due to the extreme secrecy employed by the General due to his paranoia after the Fall of Beacon and has now become distrustful and frustrated by Ironwood's refusal to reveal any of his secrets regarding the Amity Communications Tower project, the reason for the Dust Embargo and closing of borders of Atlas from the rest of the world, showing that he greatly cares for his kingdom and would like for Ironwood reciprocate the amount of trust he and the rest of the council has put in him in order to further help and benefit their home kingdom of Atlas.
Later during the events of "As Above, So Below", Sleet is showcased to have an immense temper when angered, as seen when he was able to barely control his anger when the true character of Jacques Schnee was revealed and the full destructive repercussion of his selfish and amoral actions were finally disastrously affecting the city of Mantle, where it was also shown that Sleet cares for all the citizens of Atlas regardless of whether they were from the kingdom's lower or upper class.
Councilman Sleet makes his debut in "Cordially Invited", appearing in the dinner hosted by Jacques in the Schnee Manor to discuss James Ironwood's seat in the Atlesian Council, along with Camilla and Robyn Hill.
During dinner, Sleet tells Ironwood about the council's frustrations with the General's secrecy, calling for James to trust the council and work alongside them.
