Trent MacGowen was a metahuman assassin with the ability to morph his body parts into metallic weapons in the WB TV series Smallville. He appeared as the secondary antagonist in the Season Four episode "Gone".
He was portrayed by James Bell.
Trent MacGowen was a metahuman who possessed the power to morph his body into liquid metal. At will, he could alter his body's consistency and shape his extremities into solid metal blades. Using this ability he became an assassin-for-hire until he was apprehended and landed in Belle Reve Sanitarium.
When Lionel Luthor was sentenced to prison for murdering his parents, he had Trent MacGowen released from Belle Reve and hired him to find Chloe Sullivan and kill her before she could testify against Lionel in court. Trent took the job as he wanted a normal life and Lionel promised he would reverse Trent's metahuman condition and make him normal again. Trent went to Smallville and saw a woman, Lois Lane, digging into Chloe's grave discovering there was no body but an empty coffin, proving that Chloe was alive. Trent approached her at the grave site and demanded an explanation but she ignored him. He morphed his hand into a huge sword and attacks her, knocking away Lois' prepared bottle of mace. Lana Lang appears and knocks the man in the head with the shovel, to no effect. She sprays him in the eyes with the mace and he recoils. Lana helps Lois up and they notice the man has disappeared.
Trent met with Lionel, who was recovering in the prison hospital, and revealed that he killed two security guards instead of killing Chloe. Trent abducted Chloe and brought her to a foundry bound and tied. He tried choking her to death by morphing his hand into a metal claw but Clark Kent super-sped in, throwing Trent across the foundry. Trent saw his reflection as Chloe fainted. Once again, Trent morphed his arm into a sword, but he was unable to harm Clark. Clark and Trent battle it out as he blocks Trent's sword again and again, advancing on him. Clark goes to attack him but fell right through Trent. They battled it out until Lois sneaked up behind Trent and fired a large stun gun at him.
