When the Imposter is sus adds a new entity. Its history comes from the SCP universe, where it is referred to as SCP-5167, also known as When the Imposter is sus.
SCP-5167 appears as an innocent red crewmate called Phthonus from the game "Among us". SCP-5167 wanders around peacefully, but its behavior changes drastically when provoked. This creature hides a violent and predatory nature with high damage and speed beneath its harmless exterior, making it a dangerous anomaly.

● Important FaQ
► [OLD] What is my console spaming?
Most mobs use special spawning conditions, which means that these mobs can only appear under certain conditions. If the spawning conditions work, this spam is created in the console.
► [OLD] Why can't I summon a mob?
Spawning Conditions determine which conditions must be met in order to spawn certain mobs. Some mobs only spawn above Y level 60. Some below. Most mobs can only spawn in the overworld than in other dimensions.
► Why are features missing in different versions?
It is recommended to play the newest versions of higher minecraft versions.
Not all features of MCreator available or the same in different versions.
For example: Version 1.19.2 doesn't have the feature of shield, better structure generation or custom villagers, but Version 1.20.1 does have them.
► Where does SCP-5167 spawn?
SCP-5167 can spawn anywhere in the overworld like a normal monster. However, there can only be one instance of SCP-5167.
SCP-5167, When the Imposter is sus
SCP-5167 spawns as a small, docile crewmate resembling the red character from the game "Among Us" with the name Phthonus. Approaching it causes nausea and slowness, and remaining within 6 blocks for too long, or hurting it triggers its true identity. When hostile, SCP-5167 shows it's teeth and becomes faster, deals high damage, and attacks using a long spiked tongue or a knife. It can also break glass, doors, trapdoors, leaves, and fence gates while chasing its target. Its attacks inflict Bleeding and upon death, SCP-5167 leaves behind a red corpse, marking the gruesome end of the imposter for now.
