The real Puss in Boots! In related news, saw “Puss in Boots” and it was insanely cute!!! If you like cats, Puss in Boots, or just the Shrek universe in general, GO SEE IT!
Upon listing to my soundtrack of Disney villain songs, it came to me who the most successful disney villains are.

Si and Am, the Siamese cats from “Lady and the Tramp.”
Now, why would these two…whom were only in the film forĀ about 3 minutes, warrent such a title? Simply put, they defeat the heroine. Not only do they frame Lady for tearing the house apart (thus changing the course of the story), but they indicate a goalĀ of stealing milk from a baby, after failing at eating the pet fish. Not only ambitious, but there is no indication that the cats don’t succeed in getting their dirty paws on the baby’s bottle.
Not to mention they have one heck of a song, which at the time wasn’t common for villains to have.
So in the end, they win. Not a temporary win, but they win in general. Thus…they are the most successful Disney villains of all time. Are they the best? No, but one has to give acknowledgement to these scheming felines.
