About TerrifiCon

TerrifiCon has been Connecticut’s top comic‑con gathering since 2012. Over a lively three‑day weekend, fans dive into panels, autograph sessions, cosplay contests, gaming zones, and an artist alley packed with comics creators — from legendary names to rising indie talents. Throw in standout media guests — from voice‑actors to film and TV stars — and collectible vendors galore, and you get a rollicking celebration of all things geek.
