Psycho

"You might as well be a F***ing machine"

- Psycho

Sergeant Michael "Psycho" Sykes is a former British SAS operative. He has since joined the U.S. Army Delta Force and is the third-ranking member of Raptor Team, behind Major Laurence "Prophet" Barnes, and Lieutenant Jake "Nomad" Dunn.

Psycho tends to use particularly British profanity and has the SAS insignia tattoo on the back of his head. However, it is only seen on Crysis's last level, the only time at which Sykes takes off his helmet. Before joining the Raptor Team, Psycho was in the SAS for a couple of years and was selected to join the Raptor Team after his actions as an SAS operative.

In Crysis, at the start of the game, he comes along with the Raptor Team, makes his jump out of the plane and presumably lands close to Prophet. He is seen in-game during the investigation of a frozen boat along with the rest of the team and helps Nomad until the mission at the harbor is over. After that he's ordered to follow another marine company (Alpha Company).

At the end of the game, he pilots a VTOL carrying Nomad and Helena Rosenthal on a course back to the Lingshan Islands in response to a transmission from Prophet.

In Crysis Warhead, Psycho is the protagonist and main character in the game. His journey starts when the cruiser in Hongzoo Harbor is destroyed by US air strikes. He joins the Alpha Company, jumps into a convoy and defends it until it is destroyed. Afterwards he and the rest of the company enter a VTOL and fly out to another part of the island. The VTOL is shot down, forcing Alpha Company and Psycho to find a safe checkpoint. Psycho encounters a helicopter with a container after an EMP explosion that knocks him out. After awakening, Psycho fights his way through a beach, hotel and helps his friend Sean O'Neill and some marines in his path. Later he attacks another harbor controlled by the KPA, but is captured and tortured by a high-ranking KPA commander, Colonel Lee, who's also wearing a Nanosuit. The submarine they are on board freezes later, inside the Ice Sphere, and Psycho pursues Lee (and the container) with a hovercraft. After a long pursuit, Psycho loses Lee. He moves on to find Eagle Team and they fight their way against the Ceph to the Pacific Shore Mine. When they reach the mine, Psycho departs from the team and fights his way through the mine. When he finally reaches the exit, he catches a train that is carrying the container. After a short ride on the train, he reaches a bridge of Ang River and tries to call O'Neill to extract the container at the bridge where it is blocked, but O'Neill does not respond and Psycho is interrupted by Colonel Lee and his men. Lee commands his men to drop the engineer, but Psycho is able to grab the engineer. However, the engineer begs Psycho to drop him so he can detonate the bridge and stop Lee, which Psycho follows. But Psycho fails and has to invade the airfield to capture the container. Psycho fights against both KPA, Ceph aliens, and a modified Hunter until he secures the airfield and extracts the container along with O'Neill back to the USS Constitution.

In Crysis 3, Psycho is a member of an underground resistance in New York, and is friends with Claire, commander of New York's underground resistance.

He cooperated with Prophet and other Nanosuit users in many missions before the events of Crysis 3 (but after Crysis 2), hunting Ceph locations where Prophet believed the Alpha Ceph to be.

It is revealed that he was "skinned" out of his nanosuit by CELL which was interested in researching it, as Karl Rasch erased all data related to the nanosuits before leaving the company, other nanosuit users where also skinned, and only one functional nanosuit remained, the one Prophet uses.
