- Badass in Distress: Found by Winter after he'd been captured by Xenomorphs and has to be cut free from the wall.
- Chest Burster: He's killed by one after completing his mission to retrieve the flight recorder. He does take it with him though.
- Dead Man Walking: Though he's unaware until the Chest Burster starts exploding out of him.
- Nice Job Breaking It, Hero: Didn't really do his fellow marines any favors by blowing up the umbilical bridge they were still crossing. Telling them to shoot him was a more logical solution. Somewhat understandable given the pain he was in at the time likely didn't allow much thinking on his part. He was also carrying the flight recorder that they went to so much trouble to get.
- Reckless Sidekick: Destroys an entire dropship with a grenade because there's a few Xenomorphs near it. Much to Winter's annoyance. However he goes one step further when blowing himself up to kill his chestbuster, which proves even more disastrous for all involved.
- Senseless Sacrifice: Keyes going back for the flight recorder proved to be for nothing as he blew himself up whilst in possession of it.
- Screw the Rules, I'm Doing What's Right: Ignores orders to abandon his mission to retrieve the Sulaco's flight recorder on the grounds he won't let allow his squadmate's deaths to have been for nothing. Winter agrees and tags along to aid him.
- Space Marine
- Taking You with Me: When a chestbuster begins bursting out of him Keyes decides to blow himself up with a grenade. Unfortunately he's in the middle of crossing between the Sulaco and Sephora over an umbilical bridge, thus ends up killing a fellow marine and narrowly avoiding killing even more (including Winter) in the process.
- Team Killer: Not intentional on his part but he does kill one of his fellow marines and endangers the lives of several more.
