"Uncle" Harry is a main antagonist in the 1983 Alvin and the Chipmunks TV series.
In his first appearance, Harry convinces The Chipmunks that he is their long lost Uncle and persuades them to work with him to raise money so that they can visit their mother. In reality, Harry needs to use the money to pay a debt he owes.
Harry uses similar schemes in future episodes to try and get The Chipmunks and The Chipettes to work for him so that he can steal their earnings; however, he never succeeds in actually stealing from either group in any of these episodes.
"Uncle" Harry is a burly and scruffy chipmunk with dark eyes usually dressed in an elegant and spoiled suit, a hat, and occasionally a pair of gloves and a scarf.
He always tries to trick The Chipmunks and The Chipettes by pretending to be someone else. For example, in the episode Santa Harry, he dresses as Santa Claus and asks The Chipmunks to help him set up Santa's Place.
Harry is mean, vile, and experienced at acting nicely to defraud people and steal their money. He is a con-artist that can't be trusted.
