Heroes of Ulster is a potential spin-off of Gargoyles, following the adventures of Rory Dugan (the reincarnation of the Irish hero Cu Chullain) and Molly (also known as Banshee, Cu Chullain's old enemy). These two characters had been introduced in the season two episode "The Hound of Ulster". Banshee also appeared in "The Gathering Part One", in which she was gagged by Oberon, and Cu Chullain appeared in a flashback in "Rock & Roll".
Very little is known about the spin-off. The name "Heroes of Ulster" is a working title, and was only revealed on September 30, 2008.
- This is not one of the six originally proposed spin-offs. It was revealed much later than the others, in 2008.
