Jed Leland fought for the Union in the American civil war. A ghost projection and costume was based on his pictures.
He has a corpse-like face, and he wears a Union soldier's uniform (because the original Jed Leland sided with the North in the Civil War).
He first duels with his brother, but then menaces any nearby watchers.
Powers and abilities
The holographic movie showed the brothers flying and throwing wind balls at each other. The costumed forms lacked these powers.
The real Jed Leland fought a duel with his brother Caleb, who supported the South. Both died as a result of the duel.
What's New, Scooby-Doo?
The ghost of Jed Leland was actually a holographic projection, and also the disguise of Crawdad Mike's bus driver. Crawdad wanted to make his Rattletrap bus tours more exciting and attract more tourists. He did by driving the bus onto a hidden switch in the graveyard of Leland Gables and activating a holographic projection. When the gang got too close, he and Crawdad dressed up in costumes to kidnap Daphne Blake and turn the detectives away. (Big Scare in the Big Easy)
