At first glance, the Fright Hound resembled a Great Dane, such as Scooby-Doo. The main difference would be the beast's face, which looked considerably baggier and more threatening, with visible teeth sticking out even when its mouth was closed, and fierce, glowing red eyes. After its skin was shot off in the Crystal Cove Animal Asylum for the Criminally Insane, a metallic endoskeleton revealed itself underneath the false fur.
Powers and abilities
The Fright Hound is extremely strong and resistant to damage. As a machine, it cannot feel pain, and is thus unimpeded by most injuries - even removing some of its limbs only reduces its ability to move in a technical sense. It continued to function until its primary systems were destroyed and its body rendered completely immobile after Scooby-Doo crushed it under a forklift.
Offensively, the Fright Hound is equipped with sharp metal claws and teeth. Coupled with its great strength, it can tear through metal with ease.
Scooby-Doo! Mystery Incorporated
The Fright Hound first attacked the Asylum.
It then attacked the bus that Angie Dinkley was giving tours in. Scooby and the gang arrived to discover that the bus was attacked by a weredog-like creature. Sheriff Bronson Stone grabbed Scooby, handcuffed him and took him to jail because he thought Scooby had attacked the bus.
Mystery Inc. went to the Animal Asylum to get Scooby back, due to the Fright Hound knowing he was there. Unfortunately, they were too late, as the Fright Hound had arrived moments after them. Armed guards shot off its skin, revealing its robotic form. It proceeded to attack the lawmen and defeated them effortlessly in the process. Mystery Inc. escaped in the ensuring chaos.
Then, they went to an old factory where the Fright Hound attacked the gang. The Fright Hound attacked Velma and Shaggy, but Scooby courageously engaged it in battle.
The Fright Hound was hit and mutilated by the dangerous obstacles, but it was still operational, until Scooby crushed it.
The Fright Hound's creator was revealed to be Jason Wyatt's mom. She saw how the gang had treated her son, so she created the Fright Hound out of anger and framed Scooby, hoping to destroy the gang.
- Its role and appearance, specifically its exoskeleton, is based off of the T-800 from the Terminator series of films.
