Leo Formont

Leonardo "Leo" Formont is a doctor and non-combatant who got caught up in Jefferson Island when it was used as the site for the latest game of DeathWatch.

Description
Leo first appears in Asian Town, being terrorized by a duo of Martial Artists and Sum Yung, who are debating killing him, although they seem hesitant to do so, as according to one of the Martial Artists, doctors who work at public hospitals are worth far less than privatized doctor, and manages to escape when Jack inadvertently rescues Leo by arriving on scene, causing the Martial Artists to change their target to him instead.

He is encountered again on a rooftop by Jack after he defeats Yokozuna, where he threateningly aims his gun at Jack before being calmed down by him, he then introduces himself properly to Jack, but is choked out by him when he points out how odd it is for a civillian with zero combat experience to have survived for so long, making a point to mention the virus. This causes Leo to explain both how DeathWatch was set up on Jefferson Island, due to him being in the crowd at the time, and that he managed to survive the virus because he stole a vaccine from somebody who had one.

Warning: Spoilers below
During the cutscene of Noa after Martin is defeated, it is revealed that Leonardo is the superior of Noa, and he intimidates Noa into submission, due to how profitable Jack has been.

He reappears one last time after Noa and a squad of Thugs equipped with firearms ambush Jack, shooting Noa dead under the guise of rescuing him, but he makes the grave mistake of mentioning that he had "Snuck in" after Jack when he entered the tower, alerting Jack to the reality of Leo's character, causing him to slash Leo and then interrogate him about why he chose DeathWatch, of all things, to be the stage of his plot to recuperate his company back to it's profitable former state by using both the virus they unleashed on the Jefferson Island and the vaccine, which they plan to sell at exorbitant prices. In response to Jack's questions, Leo reveals he wanted to participate in DeathWatch for the sake of it alone, and he is then ran through with Jack's chainsaw arm and sent plummeting to his demise of the tower.
