Project Moon sleeper agent

Fans of games made by indie developer Project Moon that will appear almost anywhere if one of their triggers is said or featured otherwise, examples include but are not limited to:

Red mist, name of a prominent character
Ideal, prominent theme for a story
A black mask covering someone’s entire face, a reference to another prominent character

Despite Project Moon having a statistically smaller fanbase compared to larger fandoms, sleeper agents will arrive in large numbers almost anywhere if any trigger is detected.
The name Project Moon sleeper agent comes from the fact that these persons will activate a set of behaviour when specific triggers are triggered like any sleeper agent and are fans of Project Moon, therefore Project Moon sleeper agents.

Person 1: Grr I’m so angry at person 2 I’m going to turn them into a fine red mist.
Sleeper agent 1: Bait used to be believable- holy shit is that the Red Mist.
Sleeper agent 2: The red WHAT?
Person 3: Oh the Project Moon sleeper agents are here.
Sleeper agent 3: Everyone get in here: summon a limbillion Project Moon fans
