The Ghostly Trio are the anti-heroic tetartagonists of the 1995 film Casper, and the deuteragonists of the 1996 animated sequel/spin-off series The Spooktacular New Adventures of Casper. They are the uncles of the titular protagonist, and the older brothers of J.T. McFadden.
They are voiced by Joe Nipote, the late Joe Alaskey and Brad Garrett.
