No. 'Human Centipede 2' is not based on a true story. It is a fictional and extremely disturbing horror movie created for shock value in the horror genre.
There is no factual basis for 'Human Centipede 2' being based on a true story. Horror movies sometimes like to play on the idea that they could be real to make them seem more terrifying, but this one is purely a product of the director's dark and creative imagination. It involves very disturbing and unrealistic scenarios that are not grounded in any real - life happenings.
The idea that 'Human Centipede 2' is based on a true story is a misconception. Filmmakers often come up with outlandish and grotesque concepts like this to push the boundaries of horror, but there is no real - life event that it is based on. It's all part of the fictional world of extreme horror cinema.
