Aris Jones is the only male member of a group of female teenagers called Group B. His name is likely a shortened form of Aristotle, the great mathematician.
He is portrayed by actor Jacob Lofland in movie adaptation.
In the Scorch Trials, with help from Aris who was the first maze survivor to end up in the WCKD facility, he notices that Thomas claimed that something unusual was happening in the facility just as he did so they both planned to investigate what was through the door that was guarded. The next day after meeting Thomas inside the air vents he and Aris swiped one of the guards keycard and enter the harvesting room, It is revealed that WCKD's leader, Ava Paige, is still alive and that Janson is working for WCKD, as they discuss the experiment on the Immunes and that Janson has yet to find the Right Arm, a resistance group located at the mountains. The group, including Aris, but without Tim, escapes the facility, as Janson orders his WCKD troops to track them down, where they find themselves in the deserted outside world – the Scorch.

The group eventually arrive at the Right Arm's relief camps, where other innocent survivors are present, and are greeted by Vince, who leads the Right Arm and is in charge of deciding whether they can stay or not. Later that evening, Teresa calls WCKD to her location, believing that WCKD's motivations are good, leading to an ambush by WCKD. Ava and Janson arrive and confront the Right Arm before WCKD troops capture survivors for experimentation, which were Aris, Sonya, and Minho.
