- “I'm getting too old for this.”
Hudson is an elderly, tan gargoyle with long, white hair and golden webbing in his wings. His left eye was blinded in a fight with the Archmage and is now scarred and yellow. His remaining eye is brown. Unlike the other gargoyles, he wears more clothing: a red shirt with black shoulder armor and tan trousers. He also carries a short sword usually held in the belt of his loincloth.
Hudson heavily believes in the clan's old ways and was at first baffled by the fact that everything in the modern world had a name. He then took the river's name "Hudson" for himself, due to such customs. He always advises his fellow gargoyles whenever they're having problems. Though brave, Hudson does fear losing sight in his good eye. Due to his old age, Hudson contentedly takes to guarding their home and watching TV with Bronx instead of patrolling the city.
Hudson keeps too many of the gargoyles' traditions and ways, once stating, "A gargoyle can no more stop protecting the castle than breathing the air." He keeps his Scottish accent and talks with old Scottish words, often addressing younger folk as "lad" or "lass". He carries a great sense of pride as a warrior and rarely asks for help, even when he needs it. He refuses to show weakness to a stubborn length of refusing to let his clan know of his growing blindness.
Like most of the clan before awakening to Manhattan, Hudson was illiterate, but later made a friend named Jeremy who was a blind man. He taught Hudson how to read and figured out Hudson's race as a gargoyle, which Hudson didn't tell him about because he didn't want to scare Jeremy or lose his friendship. It was his friendship with Jeremy that saved Hudson from losing his good eye when Jeremy convinced Hudson to get eye surgery.
Hudson along with the rest of his clan lived in Scotland and protected the kingdom of Avalon. He was the leader of the clean until he passed leadership down to Goliath. His scarred eye came from receiving a magical blast to it from Archmage.
One night after they fought off a raid by Vikings he and Goliath gave chase, but realize they were led into a diversion. Unable to return to the castle in time, the sun rises, forcing them back into stone sleep.
This ultimately saved his and Goliath's life when Vikings came later that day and smashed all the gargoyle statues. When Goliath came back, he informed them what happened and they went after the Vikings.
When they arrive, Magus is enraged that the gargoyles' arrival may have caused Katherine's death at Hakon's hands, and so he casts a curse on them which can only be broken when the castle rises above the clouds.
A thousand years later, in 1994, opportunistic billionaire David Xanatos claims the long-abandoned Castle Wyvern and has it reconstructed at the top of his skyscraper in New York City, along with the sleeping gargoyles.
- His name is derived from the Hudson River.
- Hudson was originally going to be called Ralph Fullmoon and was married to a female Gargoyle named Alice Fullmoon (named after Ralph and Alice from The Honeymooners), Ralph just couldn't catch a break. Everything he tried to do ended up backfiring on him. Of all the gargoyles, he was the least happy about being awake again. In later passes, Ralph lost his last name and went from the world's unluckiest gargoyle to an aging couch potato. He enjoyed the comforts of modern life and preferred experiencing them from the comfort of the indoors. The other gargoyles would come to him for advice or to catch up on the latest soap opera happenings.
- Hudson is the only main Gargoyle character to speak in a Scottish accent, despite them all coming from Scotland.
