Goliath made his debut in Gargoyles, as one of the main characters. Occasionally, he'll wear a microphone to communicate with others when out on patrol. He has two horn-like structures on his forehead. When idle, he keeps his wings folded cape-like, but will open them if angered or in flight. Goliath is a gargoyle with a muscular build, lavender skin, and long dark brown hair, brown eyes, also wearing a dark brown loincloth that is held up by a black belt.

Eventually, they get pass these doubts and confess their true feelings for each other in the three-part Season 2 finale and become a couple for the rest of the third and final season of the show. Throughout the series, Goliath has mutually fallen in love with Elisa Maza, feelings that have been uneasy between them because of their being of different species. However, after a talk with Elisa's mother Diane Maza, she helped him better understand the bond between parent and child, and he accepted Angela as his daughter. Upon meeting his biological daughter, Angela, Goliath was initially uncomfortable with her interest in their biological connection, both because gargoyle children are traditionally regarded as belonging to the whole clan (being an actual parent was foreign to him) and because he feared how she might react if she discovered that Demona was her biological mother. He later expressed to them that all of Manhattan was their 'castle', their protectorate. He still maintains a firm belief in 'protecting the castle', at first stubbornly claiming Castle Wyvern to be rightfully his and his clan's until they convinced him it was suicide to remain there. Originally having trouble adapting to the modern world, Goliath has quickly learned about the new laws and technology of the world. Goliath also acts as a father figure to the younger gargoyles. He remains mostly serious, showing very little humor. He is willing to avenge the severe injury of his clan members and prove himself if he is accused of any crimes, the former in regards to those who threaten and harm his loved ones out of malice, the latter to prove to humans that they, the gargoyles, respected the humans' law and order. Goliath has a great deal of pride, responsibility, affection, and loyalty for his clan.
