Mary Michaels, also known as Freon, was a character from the DC animated series Batman Beyond. Appearing in the episode "Heroes", she was the fianceé of Dr. Michael Morgan. Together with their friend and colleague Stuart Lowe, they were involved in a laboratory incident that left them transformed and possessing metahuman powers, leading to them forming a superhero team known as the Terrific Trio. Freon was voiced by Laura San Giacomo.
History[]
Mary was a victim of Dr. Howard Hodges's orchestration to eliminate Mike Morgan so that he could have Mary to himself. Hodges had planned only on trapping Morgan, but Mary and Stuart had also stayed late on the night of the incident. Regardless, the radiation that the trio were exposed to did not kill them, but instead greatly altered their atomic structure. Mary's body was transformed into a freezing, lighter-than-air gas, granting her the powers of flight, intangibility and cryokinesis.
Initially, Lowe, Morgan and Michaels chose to use their newfound powers for good, forming the government-sponsored team of heroes known as "The Terrific Trio" becoming overnight stars. Despite the fame and praise they received, however, the three were depressed by the fact that they could never again return to their normal lives. Worse still, the process that was used to give them their powers was soon discovered by Hodges to have a degenerative mental effect over time - a fact of which the Trio was unaware.
Fate[]
Growing increasingly insane, the Trio confronted their "friend" Hodges, only to discover the truth behind their transformations. Enraged and betrayed, the Trio went on a rampage, and were about to take revenge on Hodges before Batman intervened, and ultimately subdued them. When Batman activated the ventilation, Freon and 2-D Man were sucked into the vents. Whether or not this killed them remains unclear.
