Freight Train gained his powers from the aliens who sucked the spinal fluid from humans. The survivors who awoke from this trauma gained super powers. The person's disposition had them lean towards aspiring to be a super hero or villian. Freight Train chose to lean toward being more of a hired gun/villian.
Brightest Day: Outsiders
When the Outsiders used a Markovian jet to fly to the U.S, they accidently crossed the Canadian border and ended up getting shot down by Canadian jet fighters. Now, the Outsiders must lay low until they can prove to the Canadian government that they are not a threat. Metamorpho reluctantly decides that the only place to find sanctuary is at the Canadian estate of Simon Stagg. Stagg conviently agrees to having the Outsiders stay at his estate just so he can rub it in Metamorpho's face. Stagg gets in contact with the Canadian-American Embassy and the embassy official informs Stagg that since Markovia is still in the middle of a civil war, the Outsiders are considered war criminals until deemed otherwise.
Black Lightning doesn't believe Stagg's bad news from the embassy and threatens him to find a way to get the Outsiders into America. In retaliation, Stagg calls in Freight Train, Stagg's new hired gun who guards the entrance to his estate. He gives Black Lightning, Owlman, and Metamorpho a rough first meeting but he is called off by Stagg when he feels the Outsiders have learned a lesson about disrespecting his hospitality.
Later that same night, Java pays Metamorpho a visit while he was sleeping. For some reason, Java still had the Orb of Ra in his possession. Java uses the orb to knock Metamorpho around until Metamorpho becomes uncoscious. Java then transports Metamorpho to Stagg's laboratory which is beneath his estate. Java intends to merge Metamorpho with Chemo who has been kept in Stagg's lab for some time. Of course, the merger between Metamorpho and Chemo goes horribly wrong.
The creature breaks through the lab and makes its way to the surface. Java tells Freight Train to put an end to the creature so he teams up with Outsiders to stop the creature. Freight Train stops the creature by knocking its feet thus causing the creature to topple into a series of power lines. Chemo becomes so agitated by the electrical surge that it vomits Metamorpho before falling unconscious. When the Outsiders return to Stagg's estate, they find the Canadian army but no Stagg or Java. Freight Train feels abandoned by Stagg and gives the Outsiders the credit for taking down Chemo. The Canadian government thanks the Outsiders for their services rendered and allows them to enter the United States.
He is friends with the Ray. Stagg instructs Freight Train to capture Shaggy Man so that Stagg could siphon his power along with Metamorpho's in order to ressurect his daughter, Sapphire. Unfortunately, the process does not go well and Stagg lost his chance to bring Sapphire back from the dead. Freight Train chooses a shaky alliance with the Outsiders now that he sees Simon Stagg as someone who is much more ruthless than he is.
