Before Dr. Evil was sent back in time to 1969, his minions made him a clone. The clone was identical in every way but was "one-eighth his size". Upon being introduced to his clone, Dr. Evil immediately declared, "Breathtaking. I shall call him... Mini-Me". Mini-Me prefers to express himself through written notes.

Mini-Me has a pet called Mini-Mr. Bigglesworth, which he sometimes tries to eat, a kitten version of Dr. Evil's cat. He loves Belgian chocolate and terrorizing Scott Evil, Dr. Evil's son and rival for his affection. He is sometimes referred to and treated as a dog or other small object. Scott refers to him as "That vicious little... Chihuahua thing".
