Prior to being drained by Simone and Lena, Pettigrew wore a Confederate soldier's uniform, a gray slouch hat, trousers and jacket with white gloves. Pettigrew sports a white mustache, as well as long white hair. As a spirit, Pettigrew looked more or less the same. As a zombie, Pettigrew's uniform was tattered and ripped in several places.
At first, he looked like he tried to harm the gang, but he only tried to warn them off the island so Simone, Jacques, and Lena wouldn't drain their life force.
Powers and abilities
- Intagibility: As a ghost, he can pass through solid objects.
He came to Moonscar Island while in the 8th Louisiana regiment. He, along with the other soldiers, were drained of their life by Simone and Lena on the harvest moon, not only to preserve their immortality, but to sustain their own lives due to the curse afflicted on them when they wanted to avenge the deaths of their people when they were led into the alligator-infested waters by Morgan Moonscar and his pirate crew.
Scooby-Doo on Zombie Island
Scooby-Doo and Shaggy Rogers were terrified by the ghostly image of Pettigrew appearing in their mirror in their room in Moonscar Mansion, telling them to go away; then he stuck his hand out and moved towards them. They ran screaming out of their room, and got the others to see for themselves, but he was already gone. What they did find was that the back of the mirror had Pettigrew's name on it. In truth, he was actually trying to warn them off the island.
Pettigrew appears again, when Scooby and Shaggy are running Simone and Lena. Just as the werecats grab the two, Pettigrew and another confederate zombie lunge at them, causing them to release Scooby and Shaggy.
After the werecats were defeated and died out, Pettigrew reappeared once more as a spirit, saluting the gang and Beau Neville for defeating them and for putting the ghosts to rest in peace, apparently only noticed by a startled Scooby.
Pettigrew: Get away!
Pettigrew: Thank you all.
