"Severed" Sam Boomer is a contestant appearing only in Twisted Metal: Lost. He was once a rising star on the racing circuit until a spectacular crash took his life. His car was totaled, his body decapitated. Now he searches Midtown for the crazed fan who leapt from the stands on that tragic day and stole his severed head.
- It is unknown how Severed Sam is still able to see, as he is headless.
- His whole story may or may not be true, since he is an unfinished project.
- Severed Sam is based on the Dullahan, a homicidal unseelie fairie in the form of a headless knight of Irish mythology whose appearance is said to bring about the death of those who cross its path.
