Leo Pierce

Leo Pierce (played by Steve Byers) is a character on the television show Mutant X.

Biography
Leo Pierce was the fraternal twin brother of Lexa. They were the children of two army intelligence operatives who participated in a government facility experiment. Once the twins developed their New Mutant powers, their parents sent them to be raised in a military facility. Leo began losing control of his alters at 14, so Lexa joined The GSA in exchange for Leo's placement at a Genomex facility. Instead of receiving the treatments he needed, Leo was brutally tortured and told that they would harm Lexa as well if he told his sister what was happening. Trapped and alone, Leo was forced to develop his most dangerous alter Troy, who murdered two of the staff members in order to escape. Fearing that Lexa would send him back, or that a confrontation with Troy would end in her death, Leo avoided his sister for five years. Lexa tracked Leo with the help of The Dominion, trying to save him from capture by the ex-GSA security chief Charles Carter, who wanted to substitute Leo's heart for his own failing one. Before Lexa could reach him, however, Leo once again changed into Troy to protect himself from Carter's pursuit. Lexa tried to reason with Troy, but when Troy threatened Brennan's life, Lexa wounded him with a laser. Troy then morphed back into Leo, who died in Lexa's arms.
