Kyle Stack is a former pupil of Waterloo Road. He was friends with Denzil KellyHarry FisherHarley TaylorSambuca Kelly and Tariq Siddiqui and previously with Finn SharkeyAmy PorterLauren Andrews and Josh Stevenson

He's the main antagonist of the second half of Series 6, one of the main protagonists and anti-hero in the first half in Series 7, the main antagonist in the third and final part of Series 7 and the main protagonist in the final part of series 8.

Kyle is every teacher’s worst nightmare: mouthy, disrespectful and disruptive. He doesn’t care, which makes disciplining him a nightmare and isn’t scared of expulsion as he doesn’t want to be there anyway. There really isn’t much to recommend about this surly, aggressive child; he has none of the cheeky intelligence of Finn Sharkey or the spark and potential of Ronan Burley and if the teachers were being honest, they’d admit Kyle’s a bit of a lost cause.

Christopher Mead and Tom Clarkson always have an eye on him. He was expelled from Waterloo Road when he punched Nikki Boston in the face. Some days later, he tried to kill Finn Sharkey with a crossbow but unintentionally injured Josh Stevenson. He was sentenced to prison for approximately two years.

When he was freed, he returned to Waterloo Road but Josh's father and English teacher Tom Clarkson didn't want him in the school. After a talk with other teachers, Tom accepted him back in class, and admitted that Kyle may have changed.

Kyle realized that some people were always going to see him as an attempted murderer and convict, and subsequently tried to kill himself by jumping off the roof of the school. He was pulled from the ledge at the last minute by Tom but events following this led to Tom falling off the roof in place of Kyle. Tom had just enough breath left in him after falling the substantial height of the roof to whisper, "It's not Kyle's fault," then die in front of the crowd who had gathered. After this accident, Kyle disappears from Waterloo Road, presumably because he thought he was responsible for Tom's death.

We first meet Kyle in Episode 11 along with his mother and dog (a Rottweiler named Manic). Kyle's mother isn't particularly interested in him or his education and clearly bullies him. Kyle hates school and doesn't want to be at Waterloo Road. After some convincing, Kyle leaves his dog outside with Adanna while he goes in for a meeting with Karen, Chris and his mother. During the meeting Kyle sarcastically tells Karen that his job of choice is "drug dealer" and later tells Chris that his favourite subjects are "girls" and "fighting".

After starting a fight with Finn Sharkey in Francesca Montoya’s Spanish class, Kyle is sent to the cooler. He meets another pupil in there, Bex Fisher, who falsely accuses Kyle of sexual assault. Karen wants to exclude Kyle permanently, causing Kyle to force Bex to tell the truth. Kyle sets Manic on Bex and chase her through the school corridors with him. Bex tells the truth but Manic is taken away to get put down. Kyle’s exclusion is reduced to a one week suspension for setting his dog on a pupil.
