The show carries no official creator credit, though Michael Reaves and Greg Weisman have both described themselves as key architects of the series, with Weisman crediting himself for its folkloric, mythological, and historical elements.

The first season was almost entirely written by husband-and-wife team Michael Reaves and Brynne Chandler Reaves, who had just come off writing extensively for Batman: The Animated Series, for which Reaves won an Emmy.

After the show proved successful in syndication and for toy sales, Buena Vista pushed for a massive 52-episode second season to air daily, forcing the production team to quadruple its writing staff on short notice.

Greg Weisman had discussed with Michael Eisner using Gargoyles as the foundation for an action-oriented shared universe within Disney, comparable to Warner Bros.' ownership of DC Comics, but internal pressure from Roy E. Disney and the departure of key executives to DreamWorks scuttled these plans.

The third season was reduced to 13 episodes, moved to Saturday mornings, and rebranded as 'Gargoyles: The Goliath Chronicles' after most of the original writing staff left; Weisman has stated Disney removed him from the team early on, leading him to consider this season non-canon.

The series was originally developed with comedic influences from Disney's Adventures of the Gummi Bears and Bonkers before being reworked into a darker, more serious tone by writers Reaves, Chandler Reaves, and Perry.

New York artist Joe Tomasini sued Disney claiming his copyrighted screenplay and character designs had been copied for Gargoyles, but the case was dismissed after it was proven Disney never had access to his work.

For a proposed traditionally animated film adaptation, makeup effects artist Rick Baker was hired to create concept art and even built a physical maquette of the characters.

A film adaptation draft by Jim Kouf reimagined Goliath as a Gaelic warrior named 'Goliath MacGrath' cursed after defeating an evil sorcerer, with the modern-day plot centered on a new character, Alex Anderson, rather than the original cast; Disney liked the script but abandoned the costly project after the series ended.

Jordan Peele pitched his own film adaptation of Gargoyles to Disney in June 2018, but it was not picked up.

The 2001 English dub of the anime 3x3 Eyes included homage scenes to Gargoyles, such as a character humming the theme song, as a nod to shared voice actors including Bill Fagerbakke, Thom Adcox-Hernandez, Keith David, and Ed Asner.

The series finale of DuckTales (2017) paid tribute to Gargoyles by having character Manny the Headless Man-Horse briefly turn to stone and transform while quoting Goliath's line 'I live again!', with Keith David voicing the moment.

In the animated series Amphibia, a drawing of Goliath appears as a cameo, added by creator Matt Braly—a self-professed Gargoyles fan—partly to hint at a shared multiverse and because Gargoyles influenced Amphibia's overarching story.

Gargoyles' first season holds a rare 100% rating on Rotten Tomatoes, and the series was ranked 45th on IGN's 2009 list of the top 100 animated series.

Animation producer Bruce Timm dismissed the series in a 1999 interview as 'kind of namby-pamby... with all that Celtic fantasy crap.'
