In the Cepheus Engine (a 2D6-based Sci-Fi RPG based on classic 2D6 SRD mechanics), Pennywise the Dancing Clown (IT) is best represented not as a physical alien, but as an ancient, extra-dimensional psionic entity or "Eldritch Abomination" residing within a specific colony world or ruined habitat.
Pennywise (It)
An ancient, shape-shifting entity that feeds on fear and human psychic energy, hibernating for decades between feeding cycles.

Special Abilities
Fear Feeder
Pennywise's armor and endurance are boosted by fear. Characters targeting Pennywise must pass an END or PSI check (Difficulty: Average) before attacking. If they fail, they are Frightened (DM-2 to all actions against Pennywise), and Pennywise recovers 1D6 lost END points per round from their fear.
The Hibernate Cycle After a active feeding period (typically 3–4 weeks), Pennywise reverts to a dormant state inside planetary infrastructure or sewer networks for roughly 27 standard years.
Vulnerabilities
Shared Belief / Psychological Counter: Weapons only harm Pennywise if the attacker genuinely believes they will work, or if the party acts with total solidarity (giving a +2 DM to penetrate its Armor).
True Form: Outside its lair or off-planet, its physical form can be disrupted if forced into a physical vessel without psionic backing.
