MR is an NPC that can be found in-game and will rarely enter the elevator.  MR is a light grey carved rock with 3 small oval-shaped holes as its eyes and a wide smile.  

MR is mysterious, hostile, and has unknown intentions. Very little is known about MR as they do not normally initiate conversations with other NPCS, instead choosing to kill them.

It currently has only three conversations, those being with Folly and another with Partynoob. When MR is "speaking" every character in their dialogue (aside from spaces) is completely censored out, with the exception of the phrase "GREAT ONE" during the Folly conversation.  

MR can be found in the Shop Space floor by getting dropped off into the elevator inside a crate by MRManeuverer, though it is rare for it to appear.

Upon entering the elevator, MR prevents most NPCs from entering the elevator. MR also has a chance to cut out the lights during intermission, obstructing all of the player's screens with a black background. After the lights go back on, MR will look at the nearest player. If any other NPC is in the elevator, MR will burn them in flames after the lights go back on, resulting in them dying.

MR cannot kill Folly or PartyNoob. MR also cannot be attacked, as it deflects Snowball, Tomato, C4, Bowling Ball, and darts from the Tiny Foamer back at the responsible player, which can damage them.
