David Leatherhoff

David Leatherhoff is a prominent and infamous element present in Ice Blue's Afraid of Monsters 24/7 Server until its permanent shut-down. The concept of Leatherhoff was eventually assumed on Zorbos' AOM:DC 24/7 Server three years after the original's shut-down.

In the actual Afraid of Monsters mod, David Leatherhoff is the main protagonist and player-character of the game, being a troubled and hoodie'd young man who goes to Markland Hospital for rehab against his drug addiction only to wake up in a nightmarish and twisted world of monsters that he must gun down.

Description
On Cocyx's and Zorbos' AoM servers, David has a very different role. Instead of being the protagonist, he's portrayed as an antagonist in the servers. At random moments, Cocyx gave himself a zombie David model and used both his coding and admin abilities to haunt, stalk, and freak out the players as they try to beat AoM. Cocyx/David's abilities and scare-tactics include: One of the admins behind Zorbos' servers adopted each and everyone of these traits perfectly when assuming the role of Leatherhoff.
 * Invincibility: Despite David obviously being not very friendly to regular players, he's still technically on their team. Since Sven-Co-op doesn't allow friendly fire, this makes David invincible to other players.
 * Kill binds/Insta-kills: This also means regular players are invincible to David, so it is set up so attacking players instantly had the console kill them through suicide binds.
 * Macros: Using macros, David can open player's CD drives to creep them out.
 * Teleportation/Noclip: David can go literally any where he wants through console teleportation or noclip and could also teleport players anywhere he wants, usually in locked rooms where he corners and kills them or creeps them out by loudly knocking on the door.
 * Stalking: David's most common scare-tactic is simply staring at them from an unreachable area, usually going out of sight when they look away to see him vanish.
 * Random sounds: David regularly creeps players out by playing random bumps, bangs, screams, whispers, and other startling noises.
 * Power outages: David could also completely disable all light in a map, signaled by a loud spark soundclip playing akin to a power outage, flooding the entire level in darkness. There's no pattern to how long each power outage lasts; it can be from a few seconds to until the map is beaten.
 * Sensitivity modification: David has the ability to mess with the player's mouse sensitivity. When gone to the extremes, this effectively makes the victim utterly helpless from monsters as they uncontrollably flail around until they manually fix the sensitivity, or David grants them mercy.
