Huitzil, also known as Phobos in Japan, first appeared as a sub boss in Darkstalkers: The Night Warriors. He later reappeared in the same role in Japanese only games, Vampire Hunter 2 and Vampire Savior 2. He was first appeared as a playable character in Night Warriors: Darkstalkers' Revenge.
Huitzil is one of many robots that were created by Pyron who came to Earth 65 million years ago. When they were created, they were programmed with orders to destroy all life on the planet. After destroying all the dinosaurs, they went deep underground. Huitzil had gone into a long sleep and its functions had been dead ever since. Around 520 A.D., they were found by the Aztecs and were used for many purposes.
Later they were put into the Teotihuacan ruins and went into a long sleep again. When their creator Pyron came back to Earth, one of them awoke again and prepared to complete its original orders again. Later, due to a malfunction, Huitzil carried out new orders: to protect a child named Cecil.
