Generally, Jack Ryder is complex and multifaceted. He's a no-nonsense, outspoken, and often pessimistic investigative reporter. He's known for his aggressive manner and determination to uncover the truth. When transformed into the Creeper via a button in his wrist, his personality shifts dramatically, becoming manic and taking on a life of its own. The Creeper's laugh is incapacitating and is similar to nails on a chalkboard. He's usually on the side of good, just barely on the side of sanity.
