The connection: Jack Ryder is a news reporter on Gotham radio and television. During the investigation of an experimental scientist, he is injected with a serum that gives him unnatural strength, speed and agility. In this wild animal-like form, he is known as the Creeper. In some versions of the character, Jack Ryder and the Creeper are unaware of their shared body; in the most recent version, for example, Ryder hosts a TV show offering rewards for the capture of his alter ego.
In Arkham Asylum, you’ll only encounter Jack Ryder. He has two radio appearances, including a report about Batman’s rumored death on the island. At the end of the game, Jack Ryder is the journalist covering Joker’s rooftop theatrics.
BizarroFun Fact: In 1968, the Creeper starred in his own comic book series. It was cancelled after six issues.
