Casey was a newborn vampire whose name remained unknown throughout the novella: The Short Second Life of Bree Tanner. He took on the title of "Spider-Man", a Marvel superhero, and was called so by Bree throughout the rest of the book. She also called him "Spider-Man kid".
His name was revealed in The Twilight Saga: The Official Illustrated Guide.

This vampire first appeared when he went hunting in the bad neighborhoods of Seattle with Kevin, Bree and Diego, argued with Kevin about whose superhero figure was the best, and climbed the walls imitating Spider-Man's moves, before Kevin found a prey and fought for it with "Spider-Man".
Casey was known to have blond hair. His only other feature was his bright red eyes.
Casey was depicted as a cocky vampire who enjoyed burning his own kind and fighting within the group for sports. This is partly due to his nature as a newborn vampire. He was also easily manipulated.
He used the alias "Spider-Man" because this was his favorite superhero: he would often imitate Spider-Man by climbing on walls, which irritated Bree.
Casey's true name wasn't revealed until The Twilight Saga: The Official Illustrated Guide was published, with his name written on his profile. Throughout the book, he was known as the "Spider-Man kid" to Bree, who was narrating the story of The Short Second Life of Bree Tanner.
