- "You seem pretty smug, rooting for an entitled billionaire."
- "I just want what's best for this town. Right now, it seems pretty clear to me that that's Morgan Edge bringing jobs in."

Kyle Cushing is the fire chief of the Smallville Fire Department. He is also the son of Maryann Cushing and an unnamed man, the husband of Lana Lang Cushing, the ex-boyfriend of Tonya Martinez, and the father of Sarah Cushing and Sophie Cushing.
Kyle was also one of Morgan Edge's experiments, that caused him to be possessed by a Kryptonian consciousness, but he was returned to normal by Superman after he used his heat vision along with those of the subjekts in the Eradicator. After that, Kyle and his family were blamed by the citizens of Smallville, so he decided to move. But they were forgiven when they helped the townspeople during Morgan Edge's latest attacks.
In 2005, Kyle married Lana Lang and they had two daughters, Sarah and Sophie. Tom Mitchell was the best man at his wedding. At some point, he also began to work for Smallville fire department as a fire chief.
At some point, Kyle developed alcohol addiction and had an affair with the bartender, Tonya Martinez, that lasted for six months. During this, Kyle and Lana slept in separate rooms, Sophie bullied other kids at school, and Sarah attempted suicide by taking Lana's sleeping pills. After that, Kyle broke up with Tonya for good.
Return of the Kent family
- "What does Morgan Edge want with Smallville?
Oh, boy. He's retrofitting the coal mines to produce alternative energies. It's gonna put a lot of folks back to work around here.
Until it doesn't.
Morgan Edge ruins everything he touches."
- —Lois Lane and Kyle Cushing[src]
When Martha Kent died, Kyle went to the funeral with his family. There, he met the Kent family. After an awkward moment, they were invited to the Kent Farm while the kids went to the barn. Kyle had a brief discussion with Lois Lane about Morgan Edge, until Lana asked him to leave. After the explosion in the Shuster Mines, Kyle was called to the scene to put out the fire.
Defending Morgan Edge
Town meeting and barbecue
A couple of days later, Kyle and Lana entered a diner and saw Lois there; they greeted her and invited her to the Cushing family barbecue. Kyle noticed that Lois was researching Morgan Edge, but before he could discuss it with her, Mayor George Dean approached, distracting Kyle who chased after the mayor so they could talk.
Kyle and the mayor introduced Morgan when he came to the town meeting, introducing his plan to bring 600 jobs to Smallville. Kyle was excited until Lois began asking Morgan questions about Morgan's past dealings with New Carthage. Morgan hinted that he had the option to change his mind about working in Smallville.
The next afternoon, Kyle was the grill master of the barbecue with many people from the town at the Cushing house. When Lois went out back to get some food, she surprised Kyle by asking for ribs, a messy food to eat, since he stereotyped her as a neat, non-meat eater. Kyle used this encounter to defend Morgan further by saying that Smallville needs the money and opportunity that Morgan will provide. Lois questioned if the town was willing to work for less than it was worth; Kyle retorted that something was better than nothing. The two agreed that they disagreed.
Extinguishing the flames
Early in the morning, Kyle and Lana sat in their car as they waited for Sarah; Sarah attended a psychologist ever since she took Lana's pills but did not explain why a year ago. Kyle grew tired of waiting and wanted to enter to get his daughter, but Lana disagreed because she did not want anyone from the town to see them entering the doctor's office. When Sarah arrived, she argued that Lana was prying when Lana asked about the session. Sarah asked for Kyle to drive, so he did.
The next night, Chief Cushing helps to extinguish the flames from Lois Lane's car. When he finishes, Kyle listens as Lois blames Morgan Edge. Kyle says that the accusations are baseless; Lois listens as Chrissy Beppo says that Lois' sources are not verifiable yet. Kyle leaves.
The following night, Kyle is watching baseball at the dinner table; he says nothing as Sarah refuses to eat with them.
It's a rainy night as Kyle, Mayor George Dean, Leslie Larr, and Morgan Edge watch the Smallville Crows play. Kyle talks to Edge, who is not paying attention, about how the money Edge will provide can revamp the football stadium. Edge is staring at Lana and the cheerleaders, so Kyle tells Edge that she is his wife and an employee at his bank, causing Edge to insist that the Cushings have dinner with him. Kyle slowly agrees.
After the game, Edge sat between Kyle and his wife, as they had dinner. While Kyle and the Mayor talked, Edge talked with Lana. Kyle smiled as they conversed.
The next day, Kyle and Lana set up chairs for the town meeting. Kyle reads the Smallville Gazette and notices that the damaging article about Edge that Lois planned to write was not there. Lana is angry that Kyle said nothing the night before about Edge making her uncomfortable, but Kyle feels that since Edge was not flirting with his wife and since Edge is bringing money to the town, Lana should act friendly. Kyle feels that no matter what position he would have taken, he would have been wrong in Lana's eyes. Lana leaves for a walk.
During the town meeting, Kyle defends Edge and wants him to bring money to the town. The audience applauds his speech. The next morning, Kyle makes pancakes; Sophie brags to Lana that Kyle has not burned any. Lana amorously tells Kyle that she appreciates him.
Kyle was called in to put out the fire at the community center. Lois asks if he's seen Derek Powell and Kyle affirms that he saw Derek at the public venue. Some being puts out the fire and Kyle is surprised. Kyle returns home having been drinking. He conflicts with Lana. Kyle gets drunk on the couch talking to Sarah, but eventually she goes to the Harvest Festival.
At the mines, Edge expresses gratitude toward Kyle for his assistance prevailing upon the local area, and offers to elevate Lana to the top of the mine undertaking, making Kyle uncomfortable. Lois later heads to Kyle and Lana's home, and requests help getting into the mine to assemble an argument against Edge. Kyle, effectively annoyed on the grounds that Lana got the advancement rather than him finding a new line of work, attacks Lois and undermines her. At night Kyle is taking Lana to supper.
Back at home after supper, Lana and Kyle are discussing the coordinations of her new position. He reveals to her that he is pleased with her, regardless of whether he's still somewhat stung by Edge. Both of them begin kissing, and Sophie shows up all of a sudden to get some information about dessert. At the point when Kyle goes searching for Sarah, she's no more. They call the Kents to see if she's in the game, but he denies it and the Cushings see Tag Harris kidnapping Sarah on the house recordings. Eventually, Sarah is rescued by the army and taken back home.
Kyle helped Sarah choose a song for the musical revue and promised to accompany her with his guitar during the audition. However, before the audition, he had met with Edge's assistant Leslie Larr, who told him that Edge was interested in signing him, contrary to what Lana had told him. Depressed at the seemingly lost opportunity, Kyle got drunk and lost his hearing, and Sarah told him never to promise her anything again.
Morgan Edge's rise
Seeking to change himself for the better, Kyle took up an offer from Morgan Edge and was exposed to X-Kryptonite, giving him Kryptonian powers and made him the host of a Kryptonian consciousness. Kyle would remain in control of his body most of the time until the alien consciousness was "activated" by a sharp signal, at which point the Kryptonian would take over while Kyle remained unconscious.
Since Jordan got sick, he cannot play the piano at the talent show for Sarah, but Kyle takes over and plays the guitar, to Sarah's delight. When Emily Phan leaves, Kyle follows her and suddenly leaves the show. Kyle arrived at the Kent Farm, claiming to have followed Emily from school, and asked Jonathan to give him the gun. When Emily and a man entered the barn, Jon threw them away with the gun, but Kyle used his heat vision and blew away the gun. He grabbed them both, threatening to kill Jon before Lois' eyes, but Superman arrived in time to save them. 
Kyle woke up in a field with bruised ribs and no memory of anything that had happened since he left school. He went home terrified and told Lana that he had signed up for Edge's program and had no idea what had happened to him that night. Sarah confronts Lana for defending Kyle, and when Lana advises her to stop, she leaves to stay at Denise Olowe's house. After Sarah leaves, Lana tells Kyle that she needs to know everything that happened.
As they talk, Lois arrives and the Kryptonian consciousness took control and attacked them, but he was weakened by Lois' Kryptonite and was arrested by Sam Lane and the army. The Kryptonian is put in a Kryptonite cell and is weakened when he decides not to cooperate with the army. Later, he is visited by Sarah and Jordan and threatens them, scaring Sarah, but when Superman disabled the Eradicator, Kyle went out of Edge's control and was reunited with Lana and Sarah.
Kyle regretted defending Edge and apologized to Lois for how he treated her. The townspeople began to blame him and his family for what happened. Lois interviewed him about what happened when he was possessed by the Kryptonian, and he told her that he was able to briefly fight the programming, but felt that his family would be better off without him and ended up surrendering to it. His house was vandalized by angry citizens, but Lana and Sarah assured him that they would get through the rough patch together, and the family got together to wash up with fun.
Kyle was saddened after the town turned on his family so quickly, and suggested they move. Lana wanted to stay, but she eventually agreed when she realized that others were planning to blame her family. While Kyle was getting his stuff out of the fire department, Tamera Dalley asked him to stay, but he felt he couldn't. Kyle ended up getting an offer to replace the fire chief in Bristol County, two hours from Smallville, and he and Lana decided to move. When they told their daughters, Sarah scolded them for giving up on Smallville, and called Kyle a hypocrite for leaving town after years of complaining about others doing so.
That night, Sarah ran home and told her parents that Jordan had been kidnapped by Morgan Edge and that Sam Lane was injured. They went to Sam's wrecked car and helped Jon and Sam out of the car and help with their injuries. They took Jon and Sam back to town and found the residents protesting the DoD. Faced with the choice of leaving or staying and helping, the Cushings decided to stay. Sam asked them to help convince the people of Smallville to evacuate. As the Cushings were fleeing the city, waves of energy generated by Edge hit the city. A building was set on fire and Kyle rushed to rescue a woman trapped inside, regaining the town's respect. Kyle was offered his job back and the family remained in Smallville.
After Daniel Hart left the election, Kyle asked every member of the Fire Department to sign for Lana's election. Upon arriving home, Lana revealed that she had decided to get elected mayor of Smallville against George Dean, with Kyle's support.
Kyle cares about his community, however; due years of being a fire fighter, he is left quite bitter and prone to self-pity. He is also blind to Morgan Edge's true colors; even when Lois Lane points it out, Kyle assumes she is thinking of him as a country bumpkin; proving just how short-sighted and narrow-minded he truly is.
According to Sarah Cushing; Kyle hates everyone in Smallville; except the late Martha Kent, which implies that he isn't someone you get along with very easily. He also doesn't like Clark Kent because he and Lana already have dated. Kyle's marriage to Lana has started to fail; to the point that he sleeps on the couch.
Powers and abilities
- Kryptonian physiology: Due to having a Kryptonian consciousness placed into his body by the Eradicator, Kyle's DNA was altered, gaining Kryptonian powers.
