Ghoul was purchased in the same eBay auction that Bonk was purchased in so I do not know who made them. He is rather crudely assembled and doesn't stand on his own, AT ALL!!!! He was cut near the arch of his foot and a point to his shoe was glued on. His hat appears to be a piece of plastic or a playing card. He seems to use a New Batman Adventures Riddler figure as his base.
A Custom A Day....
I began toy collecting as a hobby back in 1990 I have always had a
need for custom figures. Toy companies begin action figure lines, begin
to release individual characters to create teams and, more often than
not leave them incomplete. Many collectors find that custom figures
pollute their collection's authenticity by not being mass produced
creations from the toy companies that created the preexisting toy lines.
I disagree. I feel a quality custom action figure enhances a
collection and help create a complete picture.
