Daniel Radford was the first person to take on the role of Leo.


A criminal recruited by a mysterious man named Taurus helped form the criminal organization known as Zodiac.


Not much is known about his early life (though it is known he was born under the star sign of Leo), but it can be assumed that Radford was a criminal who had been approached by Taurus at some point to join his Zodiac cartel. He was put in charge of the Zodiac's Los Angeles branch in the guise of Leo, with his real identity hidden from the world, including all Zodiac members save for Taurus. Also, he was head of Zodiac at any point his star sign was in ascendance.

Radford was present when fellow Zodiac member Scorpio brought the defeated Avengers before the Zodiac to be executed for interfering with their business. However, it turned out to be a trap: who they thought was Scorpio was actually Nick Fury and he and the Avengers defeated the Zodiac together.

Leo took part in many schemes and criminal activities for the Zodiac cartel, including assisting in the capturing the entire island of Manhattan and attempting to murder everyone in Manhattan born under the sign of Gemini, only to be defeated again by the Avengers.

Radford, along with many other Zodiac members, was killed by android dopplegangers controlled by Zodiac member Scorpio. The android doppleganger went onto replace Radford.
