Al is a tall, physically fit Caucasian male. He has blond hair and sun-tanned skin.
When Scooby-Doo and the gang first met Al, he appeared to be soft-spoken and friendly, but also melancholy. He also had a dark secret; his true nature was uncovered when it was revealed that he was still using drugs, and smuggling them. Al was also deceptive, using his sad story to throw himself off suspicion.
Al used to be an international skateboard champion, but soon got addicted to illegal drugs. Al was sent to prison for possession of drugs and stripped of his championship status. When he got out of prison, he took what little money he had left and opened his park.
A Pup Named Scooby-Doo
Al dressed up as the Headless Skateboarder to scare people away. This was so no one would see the dolphins he and his accomplice, Sandy Sneakers, had stolen to smuggle in their illegal drugs. It was unknown whether Al was using the drugs for his personal consumption, or whether Sandy was making money from selling the drugs.
However, given that it did not make much sense for Al to be scaring away his own customers, it is most likely that he was making more money selling drugs than he could from the profits of his skate park. They also tried to make it look like Red Herring was the monster as one of his pranks. They were taken into custody by Gnarly Charlie, who was an undercover FBI agent sent to investigate the drug smuggling operation.
