Red is a supporting antagonist in Stuart Little. He is one of Smokey's henchmen.
He was voiced by famous comedian/actor David Alan Grier.
He was first seen when he asks Stuart Little where he's going and called him Murray, and was chasing him in the roaster alongside Smokey and Lucky but they failed to get Stuart as he was going back to his home. He was later seen with Monty, Lucky and Smokey and was seeing Stuart and Snowbell and then when Snowbell was almost breaking the branch he was standing with Lucky and Monty and then the branch broke and all 3 of them were screaming and were defeated by falling into the water and Red was saying he raver drowns and escapes from the water with Lucky and Monty. After they got defeated, Red and Lucky were never seen again in the rest of franchise but Monty was.
Like the other alley cats, Red is snarky and evil. The only difference between Red and the other alley cats (especially Smokey) is a delta and lacks the intellect of the others.
