In the comics there is no actual character concretely known as Weapon XI (Weapon X, for those who don't know, is Wolverine) although other products of military experiments have been codenamed with Weapon *roman numeral*, (for instance, Captain America has been called Weapon I). Using this, Deadpool would be known as Weapon XI, as he was the next person in the Weapon X/Plus program even though he has not explicitly been stated as such. Also, In the film he joins the Weapon X program to travel to far off places and meet new and exciting people and kill them (As heard in the 'Wade Wilson' character bio on the Marvel website), But in the comics he had joined to find a cure for his terminal cancer.As for this character (the following information may contain spoilers) , apparently the makers of the movie took creative licenses with Deadpool/Wade Wilson's character where seems that Wade Wilson (played by Ryan Reynolds) is the merc with a mouth but he's presented with no actual scars or the Deadpool replica costume known in the comics. During the movie Wade Wilson will undergo some changes in a procedure by William Stryker turning him to a silent killing machine implanting blades in his forearms, giving him laser blazing eyes from Cyclops, the teleportation power of Wraith and of course he would have the healing factor of wolverine/Sabretooth. That's when you witness his form being scared and disfigured being the character Weapon XI (played by Scott Adkins). It was revealed in a thread form Scott Adkins' fansite that he will have the last fight against Wolverine in the movie and that's what we caught a glimpse off in the official trailer where we witness Weapon XI doing a flying spinning kick in the face of Wolverine with blades appearing out from his forearms. According to some inside leaking news, Weapon XI will ruin a huge part of the building or settlement where the last fight happens and so he will suffer severe damage and trauma that his own healing factor can't withstand hence his body will reject all of the implanted mutant parts and he'll be the good O disfigured Deadpool we all know from the comics. A note is that Weapon XI has his mouth sewn and that obviously is because Wade Wilson is the kinda guy who won't ever shut up! So Stryker sewed his mouth in the process of the procedure. The markings on Weapon XI's body are the same markings that Wolverine had when they implanted his body with Adamantium and basically the markings will be clear on Weapon XI's body in the fight because Stryker was surprised by Wolverine breaking into the place searching for Sabretooth so he orders to wrap up the procedure as fast as possible.
