- Alex Mercer

Alexander J. Mercer, or simply just referred to as "Alex Mercer" is the main protagonist of Prototype, the main antagonist of Prototype 2 and an upcoming DLC character for PlayStation All-Stars Battle Royale. His In-game rival is Leon S. Kennedy .



Alex Mercer was the head researcher of the Blacklight Project at a biological researching company known as Gentek. After he realized that Gentek researchers who were involved with the Blacklight Project were being murdered by the elite army Blackwatch, he he tried to flee the city with his research, only to be uneventfully caught at Penn station in the end. Before getting killed, Alex smashed his research containing a deadly virus onto the ground, causing it to spread throughout the city. As his body was about to be dissected by two scientists, Alex came back to life, having been resurrected by the virus which constructed his body and gave him new powers. He then started using those powers to take down those who were responsible for the downfall of the Blacklight Project.

Name: Leon S. Kennedy

Reason: Alex is stalking Leon from above when he drops onto the arena. Leon, having seen what Alex is capable of, starts to threaten him thinking that he may be a B.O.W. Alex laughs and says he will show him that he is more than just a weapon. Leon asks for a demonstration and Alex tells him that it will be demonstration he'll regret.

Connection: Both Prototype and Resident Evil have a theme focused on zombies originating from bio-warfare/bio-terrorism, so instead of coming back from the dead through magical means, they are revived through a special chemical.
