Greg Grogan is an astronomer.
Physical appearance[]
Greg is a skinny man with a large forehead, round glasses and short black hair with white streaks. He wears a collared shirt with two breast pockets, jeans with a belt and shoes.
Personality[]
He was amateur, but a bit of an odd person who was obsessive on wanting to get sightings on space life forms and mapping out parts of the galaxy after getting an observatory built in the parks place. His obsession was even enough to creep people out.
History[]
Scooby-Doo! and You[]
Fred and the girls encountered Greg on an observation platform located at the end of High Point Park, acknowledging them about the miles across the land it was built. After revealing himself as an astronomer, he goes to explain that he had been begging the town for years that he wanted to build a state-of-the-art observatory for mapping other galaxies, looking for comets and even life in space, which turned out he had seen sightings of six out of seventeen UFOs people reported about.
After the three said goodbye, he was added to the suspects list of being behind the alien haunting the park, but was immediately proven innocent, even though he wanted to prove aliens were real, he didn't intend on making people think they were scary and mean.
