Isaac Clarke

Isaac Clarke was a ship systems engineer working for the Concordance Extraction Corporation and the protagonist of the Dead Space franchise. Prior to the Second Aegis VII incident, he was part of an emergency response unit of the USG Kellion, sent to the USG Ishimura to investigate and handle the ship’s mysterious communications failure. Apparently the sole survivor of the incident, Isaac became stranded in space for a long period of time before he was rescued by an Earth Government ship. For the next three years, Isaac was held in an asylum on Titan Station and was diagnosed with dementia, resulting in haunting illusions that taunted him throughout the game. In Dead Space 3, he still had the blueprint to destroy and create the Markers. However, in the Awakening DLC, he experienced the effects of dementia once again when he was exposed to one of the Brethren Moons.
In the DZ2K series, he was one of the main protagonists in DZ2K9 and he's set to be one of the main protagonists in DZ2K19, 10 years after.

It was revealed that Isaac survived the Brethren Moon and he's now retired. However, he was soon brought back into fighting by Xin Xianying, Xin Pi's daughter. 
Xianying told Isaac that The Marker is seen once again by the Mishima Zaibatsu. 
Isaac then told Xianying that Xin Pi is also known as Xavier Pine, one of the people from the USG Kellion.
