Rory McKenna is the son of Quinn McKenna, a United States Army sniper.


Rory has a disorder in the autism spectrum, possibly Asperger Syndrome given his bullies nicknamed him "Ass-Burger". The condition also gives him savantism of sorts, enabling him to restore chess boards to their previous condition before the pieces were knocked down by said bullies. Rory is an avid video gamer, liking shooters in particular because they remind him of his father (even if Quinn had forbid him from playing that genre).

In October 2018, Rory received a package originally intended for Quinn's PO box. Inside were a mask and wristband worn by an alien creature, with Rory removing a device that worked as a portable computer from the latter and managing to decode how it worked.
