Uncle Harry

Harry (sometimes known as Uncle Harry) is the main antagonist in Alvin and the Chipmunks animated television series. He was an anthropomorphic chipmunk who loved to take advantage of others and con them in order to make himself rich, even going as far as playing on emotions to get what he wants: such as when he managed to convince the Chipmunks he was their real uncle - when they found out the truth they returned to Dave and from that moment on their relationship was antagonistic.

In recent media, Harry no longer exists (at least not as of yet) - his role as one of the Chipmunks' main antagonists has instead been passed on to Ian Hawke, who has many of the same negative traits as Harry.
