Week Σ - Vs. Demetrios is a Game Mod for Friday Night Funkin' that adds a new week and three new songs. There isn't exactly a plot to this mod, but it has Boyfriend fighting an alien known as Demetrios...for whatever reason.
Unfortunately, the mod's creator, PlazerLazer, has discontinued this mod due to reasons left completely unexplained. His mod may not have anymore future updates, but Demetrios still got a Cameo Battle in Times & TribulationsVs. Omega, which did give him a surge in relevance.
Not to be confused with FNF Week Sigma.
Week Σ provides examples of:
- Badass Longcoat: Demetrios wears a longcoat and has the hood up during "Prelude".
- Eye Colour Change: Demetrios's four eyes change color depending on the note he's singing.
- The Gloves Come Off: After "Prelude", the game cuts to Demetrios with the hood and visor off, and his next songs ("Nova" and "Quasar") are more difficult.
- Guest Fighter: No one in his mod, but Demetrios appears in Times & TribulationsVs. Omega as a Cameo Battle. Here, he's now a bored science experiment held captive at a lab, and also has a new ability to bring the player's HP to 1 with a special note.
- Noodle Incident: It is currently unknown why Boyfriend and Demetrios are rap battling in the first place, and - seeing as the mod is discontinued - there may not ever be an official explanation.
- One-Way Visor: Demetrios's visor does a great job at concealing his two pairs of eyes in "Prelude".
- Shock and Awe: Demetrios's ears will occasionally spark with electricity during "Nova".
