— Big the Cat, Sonic the Comic #184
Big is a very large and burly anthropomorphic cat. The majority of his body fur consists of two shades of purple: light and dark. A striped pattern runs up his arms and tail. His feet are covered in dark purple fur up to his ankles as well as the outer tips of his ears, while his upper legs, back, and sides are covered in light purple fur. White fur covers his chest, torso, inner ears and his muzzle with the addition of cheek tuffs. His eyes have yellow scleras with black irises. His preferred attire consists of tan gloves, sandals, and a matching belt with a gold buckle. He is also seen carrying a fishing rod.
During a fishing trip, Big had settled down and was quietly fishing outside Robotnik's Retreat, oblivious to the great battle against Chaos occurring nearby. His fishing was interrupted by Chaos, who had been returned to his Drakon form and thrown out of the retreat by Super Sonic. As Chaos fell down, Big, much to his confusion, caught a glimpse of the Drakon falling into the pool he was fishing in.
Big is somewhat absentminded and not too quick on the uptake, as he stuttered and was caught completely off-guard when Chaos landed in the pool next to him.
- Writer Nigel Kitching has said that he was determined to include Big in the comic. He felt that Big resembled a Miyazaki character and would have loved to build him up into a real personality, but the comic's cancellation prevented this.
