!Major Laurence "Prophet" Barnes

The leader of Raptor Team.

* AngryBlackMan: In the flashbacks of Crysis 2. [[spoiler:His discussion with Hargreave leaves it completely justified.]]
** Used to ''awesome'' effect in the final level of Crysis 3. [[spoiler: How do you resist a super-powerful EldritchAbomination's attempt to [[YouWillBeAssimilated assimilate you]] into its HiveMind?]] Prophet's answer is to get ''[[ThePowerOfHate mad as hell]]'' about it.
* BackForTheDead: In Crysis 2. [[spoiler:Subverted at the end.]]
* BadassAbnormal: Due to the Nanosuit.
* BadassBoast: Practically ''every'' line of dialogue Prophet says in the final mission of Crysis 3 is this.
-->"NO. This suit is MINE. Let me show you what I CAN DO!"
* BadassInCharge: Of Raptor Team.
* BaldOfAwesome
** BaldBlackLeaderGuy
* [[spoiler:BlessedWithSuck: How he views the Nanosuits after learning they are symbiotic.]]
* [[spoiler:BrainUploading: 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.]]
* [[spoiler:DeadManWalking: 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.]]
* DeadpanSnarker: In 3 [[spoiler:and ''Legion'']].
* [[spoiler:DeadPersonImpersonation: 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.]]
* [[spoiler:DrivenToSuicide: "Had to break the link" to the Nanosuit 2, so he shot himself in the head after giving it to Alcatraz in Crysis 2.]]
* ElitesAreMoreGlamorous: A member of the Delta Force Raptor Team.
* [[spoiler:FusionDance[=/=]GrandTheftMe: Of a sort with Alcatraz and SECOND over the course of ''Crysis 2''.]]
** [[spoiler:''Crysis 3'' mostly retcons this away, with Alcatraz's mind dying at the end of ''2'' and Prophet's mind taking over the body.]]
* IJustWantToBeNormal: His opinion in 2 and 3 is that while he's willing to use his abilities to help, he'd happily remove his suit and move on. [[spoiler:Pity [[ClingyCostume he]] [[BlessedWithSuck can't]] [[DeadManWalking do that]].]]
* LastOfHisKind: Subverted in 3. While he's the last anti-CELL Nanosuit wearer to not end up "skinned", [[AllThereInTheManual supplementary information in intel items]] reveals that [[EvilCounterpart they have their own operator]], [[TheGhost Silverback]].
* MajorlyAwesome
* TheProtagonist: Of the whole plot.
** SupportingProtagonist: In every game but ''3'', where he's more up front.
* [[spoiler:RedRightHand]]: In ''3'', [[spoiler: the Nanosuit's replication of Prophet's human body would be perfect if not for the glowing bits in his eyes.]]
* [[spoiler:{{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.]]

!Sergeant Michael "Psycho" Sykes

Originally SAS, seconded to Raptor Team.

* AscendedExtra: From team member in the original Crysis to PlayerCharacter in Crysis: Warhead.
* BadassAbnormal: Due to the Nanosuit.
** BroughtDownToBadass: Even after CELL skins off his Nanosuit, he's still a very competent BadassNormal, showing off exactly why he was in both Delta Force and the British SAS.
* TheBusCameBack: Returns in Crysis 3 after an absence in Crysis 2.
* [[spoiler:DeadManWalking: Due to the Nanosuit. Subverted when CELL ends up "skinning" off the suit before 3.]]
* ElitesAreMoreGlamorous: A member of the Delta Force Raptor Team.
** Was also previously British SAS.
* IJustWantToBeSpecial: In 3, he has a lot of angst over being a normal human. [[IJustWantToBeNormal Prophet]] [[WhatTheHellHero takes issue with this]].

!Major Clarence Strickland

Leader of the US Marines detachment in ''1''.

!Alcatraz

The player character of ''2'', a US Marine sent to New York City by submarine. Prophet finds him and gives him his Nanosuit.

* [[spoiler:DeadManWalking: 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 DyingMomentOfAwesome, and Prophet is walking around in his corpse.]]
* DeadpanSnarker: His narration in ''Legion'' makes it clear he is a very snarky bastard.
* DecoyProtagonist: In ''2''.
* [[spoiler:DyingMomentOfAwesome: 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.]]
* FeaturelessProtagonist
* [[spoiler:FusionDance[=/=]GrandTheftMe: Of a sort with SECOND and Prophet over the course of ''Crysis 2''. See Prophet's example.]]
* GreenEyes: Not that you can tell in the suit.
* HeroicMime: Justified heavily. For the beginning, he's hungover, and then [[spoiler: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.
* ManInTheMachine
* [[OnlyKnownByTheirNickname Only Known By His]] CodeName: Unlike the other Nanosuit wearers, his name isn't even mentioned at all, nor his rank.
* [[spoiler:OurZombiesAreDifferent: Sort of. In 3, Prophet commandeers his corpse to keep going for over another 20 years.]]
* PopCulturedBadass: His narration in ''Legion'' is riddled with pop culture references, some of them quite subtle.
* SemperFi
* WhyDidItHaveToBeSnakes: 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.

!Jacob Hargreave

One of the founders of the Hargreave-Rasch Biomedical MegaCorp.

* CorruptCorporateExecutive: In a sense. However, he is genuinely trying to help, in his own way.
* [[spoiler:DeathEqualsRedemption: With his final words, he calls for CELL's remaining forces to stop fighting against Alcatraz, ultimately saving New York.]]
* [[spoiler:ItsAllAboutMe: Thinks that only he is worthy of using the Nanosuit to combat the Ceph.]]
* [[spoiler:ReallySevenHundredYearsOld[=/=]TimeAbyss: See FridgeLogic on the main page.]]
* [[spoiler:WellIntentionedExtremist: The creation of the Nanosuit itself can be considered extremist, but his methods overall can be considered this.]]

!Karl Ernst Rasch

The other founder of Hargreave-Rasch Biomedical.

* [[spoiler:BrainwashedAndCrazy: By the Alpha Ceph.]]
* [[spoiler:DyingAsYourself: Prophet lets him do this, breaking the link to the HiveMind before a Ceph kills him.]]
* HonestCorporateExecutive: He's a lot nicer than Hargreave. [[spoiler:Or at least the Alpha Ceph is.]]
* [[spoiler:ReallySevenHundredYearsOld: See Hargreave.]]
* ShadowArchetype: Like Prophet, he accesses Ceph technology. [[spoiler:Unlike him, he lost his identity to the HiveMind.]]
* [[spoiler:ShockAndAwe: Kills Claire with this when controlled.]]
* WalkingSpoiler: [[spoiler:His being alive is spoiled at the end of 2, meaning everything in 3 counts as this for him.]]

!Semiautonomous Enhanced Combat Ops: Neuro-integration Delivery AI (SECOND)

The AI included in Nanosuit 2.0.

* AIIsACrapshoot: Averted. Its own creators are dumbfounded by the sheer extent to which it will work to keep its user alive.
* ArtificialIntelligence
* [[spoiler:BigDamnHeroes: Rejects the suit rip Hargreave orders, allowing Tara Strickland to save Alcatraz's life.]]
* CaptainObvious: At times, its advice and notifications of threat levels come at points where it's rather obvious to the player.
* [[spoiler:FusionDance: With Prophet and Alcatraz over the course of Crysis 2.]]
* [[spoiler:ImportedAlienPhlebotinum: 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.]]
* MachineMonotone

The leader of the CELL forces in ''2''.

* GeneralRipper: Hates the Nanosuit programme...
