Bear5 is a surreal internet character depicting a low-resolution, bright blue 3D model of a bear, often associated with Freddy Fazbear from Five Nights at Freddy's. It first gained traction in early 2024 within the 'brainrot' and shitposting communities, frequently appearing in videos alongside the track 'Sleepwalker' by akiaura. The character is known for its stiff, repetitive dancing animations and its rivalry with another entity known as Bear6. Its popularity stems from its uncanny, early-internet aesthetic and its role in the bizarre, lore-heavy world of modern surreal memes, where it is often treated as an unstoppable or cryptic force.
