Kevin Winnicot

Kevin Winnicot is a supporting character in the Xenosaga series. He is the original developer of KOS-MOS and was Shion's boyfriend before his death.

History
Kevin was the chief engineer of the KOS-MOS project within Vector Industries First R&D Division. He was Shion's superior as well as her boyfriend. Kevin was in charge of both the hardware and software components of KOS-MOS. In Episode I, Kevin is shown in a flashback of Shion's where she is working at night on KOS-MOS. He brings Shion coffee and tells her about how much he is looking forward to seeing KOS-MOS wake up, but is not sure what to tell her. Shion tells him to give the simple message of good morning which gets him to relax about it. We also see an earlier flashback when he asks Shion if KOS-MOS has a heart.

Two years before the events of Episode I, he was killed during an incident when the U-TIC Organization attempted to seize KOS-MOS and she went out of control. Flashbacks reveal that Kevin was the one who handed the U-TIC officer in charge, Andrew Cherenkov, a device to use to activate KOS-MOS. Kevin intentionally arranged for the incident to occur such that he would be killed and he became the Red Testament.

A photo displayed by Juli Mizrahi during the game also shows that he was the assistant of Joachim Mizrahi when he was younger.

Episode I
During the present day events of Episode I Kevin appears exclusively as the Red Testament, with his identity hidden by a mask. He can be found conversing with Wilhelm in several scenes including a discussion about information they have been reported on by KOS-MOS. Later he also converses with Virgil, who has recently become the Blue Testament. He tells him to come back and that Virgil will have to get used to hearing his voice in his head.

Episode II
Kevin appears in a flashback talking with Shion about how KOS-MOS' awakening will lead humanity towards the future. He has been working on a craft that is part of KOS-MOS' equipment and will be able to interact with hyperspace on its own. He tells Shion that he wants to believe that KOS-MOS will be more than just a wanton instrument of destruction.

As the Red Testament, Kevin appears in a scene speaking with Wilhelm, telling him that they've detected Albedo's ascension. He appears at the Ω System along with the Blue and Black Testaments and kills Sergius then revives Albedo. He also appears with the other Testaments and Wilhelm in the game's last scene.
