Team X were a group of mutant soldiers led by William Stryker.
Biography
X-Men Origins: Wolverine
Team X travels to a facility in Nigeria and attack the soilders guarding it. Agent Zero attacks first, shooting down most of the guards. Victor then climbs to the roof to serve as a look-out. Soon after, Fred Dukes destroys a tank single-handedly. The team then enters the facility and rides the elevator to the twelfth floor. Once there, Wade Wilson single-handedly kills most of the guards present on the floor. The facility's commander attempts to reach for his shotgun before John Wraith stops him. Stryker gets some useful information and heads to a nearby village.
After arriving, the team interrogates the villagers at gunpoint. Wade, who could speak the local language, serves as the translator. Due to the villagers' general lack of cooperation, Stryker orders to Victor kill them. The rest of the team is about to follow suit before Logan intervenes, stopping Victor from killing a woman. Logan then quits the team, having developed a strong aversion for their violence. Stryker however used a sleeper agent, Kayla Silverfox to keep track of Logan during his departure, by feigning a romantic relationship with him.
Following Logan's departure in Lagos, Victor was never the same and didn't bond well with the other team members. Stryker then expanded the focus of Team X's brief to revolve around hunting other mutants across the world and bringing them in for experimentation in Stryker's military programme. John Wraith, Chris Bradley and Fred Dukes felt conflicted about this, but kept quiet. They later left the team and went their separate ways, seeking to hide from their past history with Team X.
Although Team X had all but disbanded, Wade Wilson, Victor Creed and Agent Zero remained by Stryker's side faithfully. Stryker concocted a plan to create the ultimate mutant killer by distilling mutant abilities into a single entity, aiming to use Wade to achieve this goal. He ordained Victor to hunt down the remaining members of Team X and harvest a sample of their blood. Victor tracked Bradley down in a circus and killed him, taking a sample of his genes, and thus, his ability of technopathy.
To arrange for a meeting with Logan, Stryker fabricated the story that someone was hunting down their old team. Logan refused to come back to Team X, to which he ordered Victor to "kill" Logan's girlfriend Kayla. This gave Logan the incentive to return to Stryker's company and subject himself to an adamantium transfusion procedure in order to exact his revenge on Victor. After the procedure Logan realised he had been tricked by Stryker into becoming a test subject to determine if an adamantium procedure could be pulled off, and before they could terminate him he broke out and escaped.
Logan travelled to Las Vegas to meet up with John Wraith and Fred Dukes, who told him of what happened after his departure from Team X and how Stryker held all his mutant prisoners in a facility called "The Island". Victor was sent to deal with Dukes and Wraith, killing them and harvested both of their powers for the Deadpool. Logan then travelled to Three Mile Island with Gambit to stop Stryker, where he realised that he was played for a fool and fell directly into Stryker's plans.
Logan fought Victor over his role in Kayla's death, but Logan managed to defeat him and escape. Stryker was forced to prematurely activate Deadpool to deal with Logan after he freed his mutant prisoners, but with the assistance of Victor, Deadpool was killed.
Insignia
During their mission being dropped into Lagos, Nigeria, some members of Stryker's military mutant team (including William Stryker himself) wore distinctive military patches on their uniforms. This consists of a skull wearing a green beret with an eagle's outstretched wings behind the skull, with the Latin inscription "Vaculum Unitatis" emblazoned directly underneath the emblem.
