Brain Uploading: One of the two operators of the Nanosuit 2 in Crysis 2. The entire time, yes. And in Crysis 3, he's essentially performed a Gundamjack in a benevolent sense to keep fighting in Alcatraz's corpse.
Dead Man Walking: Due to the Nanosuit. Also becomes quite literal in 3, where he is literally walking around in Alcatraz's corpse. This is lampshaded multiple times.
Dead Person Impersonation: The retcons in Crysis 3 turn the entirety of Crysis: Legion into this; turns out Prophet was using what small fragments were left of Alcatraz to impersonate Alcatraz in front of Marine command.
Driven to Suicide: "Had to break the link" to the Nanosuit 2, so he shot himself in the head after giving it to Alcatraz in Crysis 2.
Father to His Men: NEVER ever mess with anyone on his team, he WILL kill you as some CIA assholes found out the hard way.
Fusion Dance/Grand Theft Me: Of a sort with Alcatraz and SECOND over the course of Crysis 2. By the time of Crysis 3, neither Barnes nor Alcatraz exists anymore. They've merged into a gestalt that calls itself Prophet, with some of Barnes' memories.
Red Right Hand: In 3, the Nanosuit's replication of Prophet's human body would be perfect if not for the glowing bits in his eyes.
Transhuman: Becomes this over the course of the main games and the process is completed by the end, when the unlocked Nanosuit 2.0 assumes the form of Barnes' human body and demonstrates its cloaking ability in that form.
The player character of 2, a US Marine sent to New York City by submarine. Prophet finds him and gives him his Nanosuit.
Dead Man Walking: Moreso than any other Nanosuit wearer. The injuries he sustained in the movement tutorial would have and will kill him if he takes the suit off, and the suit itself is harvesting his failing organs as fuel to keep him alive. This becomes literal in 3, where his mind "was lost" in 2's Dying Moment of Awesome, and Prophet is walking around in his corpse.
Deadpan Snarker: His narration in Legion makes it clear he is a very snarky bastard.
Dying Moment of Awesome: The retcons in Crysis 3 turn the finale of Crysis 2 into this. During the destruction of the Central Park lithostructure, Alcatraz's mind was "lost", allowing Prophet to take over.
Empowered Badass Normal: Though he is essentially dying throughout the incident, he can wipe out an entire CELL force thanks to a combination of his experience in the Marines & the 'Suit.
Heroic Mime: Justified heavily. For the beginning, he's hungover, and then his lungs are injured beyond repair. In Legion, however, he talkative. Very talkative, and the 2.0 suit is actively making him more eloquent and verbose.
Why Did It Have to Be Snakes?: According to his narration in Legion, he is actually afraid of water due to a bad incident in his childhood. he got over it for the most part during training, but the sinking of his submarine brought it all the way back to the forefront.
One of the founders of the Hargreave-Rasch Biomedical Mega Corp..
Hargreave: Cleaning up - it's ingenious, isn't it. Think of the Argentine Cattle Crisis two years ago. Or the British BSE outbreak in the last century. The issue was not slaughtering the animals, that was easily done. The problem was disposal. What do you do with the millions of rotting corpses? Well, there you see the answer the Ceph have evolved. They wipe us out, they break us down, they reduce the environmental impact almost to zero. Exemplary.
Affably Evil: "Evil" is pushing it due to his methods, but Hargreave is charismatic, well spoken and reasonable. Even when things don't go his way near the end, he still manages to be helpful. See Death Equals Redemption
Well-Intentioned Extremist: The creation of the Nanosuit itself can be considered extremist, but his methods overall can be considered this.
Wicked Cultured: He's very eloquent with his vocabulary and when you visit his personal quarters near the end of the game, he has a massive library with suits of medieval armor and Nanosuits in glass cases.
Big Damn Heroes: Rejects the suit rip Hargreave orders, allowing Tara Strickland to save Alcatraz's life.
Captain Obvious: At times, its advice and notifications of threat levels come at points where it's rather obvious to the player.
Fusion Dance: With Prophet and Alcatraz over the course of Crysis 2.
Imported Alien Phlebotinum: The only reason that SECOND is able to integrate with the Ceph Nano material and sabotage their technology is because the Nanosuit itself is stolen Ceph technology applied to a human form.
Major Strickland's daughter and a CELL special advisor. Is actually an undercover CIA operative. Later became a Senator.
Colonel Sherman Barclay
The leader of USMC forces in NYC in 2.
Better to Die Than Be Killed / Driven to Suicide: In Crysis: Escalation, 24 hours after the U.S. government sells the Marine Corps to CELL, a group of CELL operatives arrives at his home to arrest him for treason against CELL. He kills the first group of 8 sent to take him in, but after seeing more reinforcements arrive, he chooses to shoot himself.
