- "I just met you, and there's no doubt in my mind that you're a force for good in this world." - Patricia Swann to Clark Kent, Traveler
An attractive woman in her mid-twenties with big blue eyes and red hair. Her physique is slim and she appears to be in good general shape for her age.
Patricia was a very intellectual, smart and caring young woman. She, like the other children of the Veritas group have had their lives forever changed by Lionel Luthor and his obsession with Clark. Patricia was very strong-willed and exhibited a passion for her father's work through her desire to continue working with Clark. She was not easily swayed by Lionel's threats and proved to be very courageous.
Years after her father died, Patricia Swann learned about Veritas and the Traveler that was to come to Earth. She also found a link in the deaths of her father as well as Robert Queen and Laura Queen, and suspected Lionel Luthor as the one responsible. Patricia confronted Lionel with proof of the murders, and asked Lex for help, but even he was clueless about Veritas, even after seeing a drawing of the Veritas symbol. 
Lionel agreed to a deal with Patricia, so she went to see him in a warehouse where Clark Kent was being held. Patricia wanted Clark to be set free before giving Lionel the evidence, but she was knocked unconscious by Pierce. 
After Clark was rescued by his cousin Kara Kent, Patricia and Clark talked things over at the Kent Farm over a cup of coffee. She gave him her father's journal that was filled with Kryptonian symbols. Patricia also decided to move to Metropolis in order to be closer to Clark, wanting to be there for him, like her father before her. Unfortunately, while driving back to Metropolis, Patricia was shot and assassinated by her driver. Her death was ordered by Lex as afterwards he examined her bloody necklace. 
Approximately a week later, Patricia's body was found in a lake with a bullet to the head. Soon after, Lois Lane and Jimmy Olsen found incriminating documents left by Lionel further indicating Lex's involvement in Patricia's death. 
After he was shot in Detroit,  Lex began to remember events from his childhood like the days when he played alongside Patricia, Oliver and Jason and recollected his father's secret meetings with the group known as Veritas. Patricia's parents had been part of Veritas, which had been awaiting the Traveler's arrival on Earth. 
- Unlike the children she played with as a child (Oliver Queen, Jason Teague, and Lex Luthor), Patricia has never been a main character in Smallville.
- In a parallel world where Clark was found and rasied by Lionel Luthor, according to Oliver Queen of Earth-2, Patricia Swann and her father were murdered by Clark Luthor/Ultraman. 
- Her autopsy appears to say she is 26 and 5'8" tall.
