Marshall Quenton

Biography
Marhsall Quenton's story starts off with him being saved from the chaos of the Kalsimer Invasion of Earth, along with Zyland Mantharas and Ariel and Sage Winter. He developed minimally during his first saga appearances, eventually leaving the group to pursue his own life. He briefly mentioned during his time with the group that he was the head of a Robotics Engineering Company before the Kalsimer destroyed Earth. Marshall would not return again until the MILE Saga, aside from a single, brief, and unimportant cameo appearance during a seemingly random point in the story.

Marshall presumably went his own way to settle down and have a quiet, happy life. It was soon discovered that this was not the case, as he had made his return in the MILE Saga as the primary antagonist and head of the MILE group. His conflict with the protagonists slowly escalated. His organization, which was surprisingly far more technologically advanced than the IA at the time, waged a war against the massive republic and was winning for a time. He even successfully planned and carried out heists on Waternaux City itself.

Vex had made the necessary calculations and had gathered the necessary data to pinpoint the location of the MILE HQ. It was discovered to be somewhere in what used to be the United States. Some members of the group, most notably present-day Sven Waternaux as well as a past and future version of himself, David Dynamo III, Mr. Strange, and others invaded the facility after bypassing the massive radiation output of the facility. They fought their way through the facility with their primary goal being to destroy MILE's time anchor, and their secondary to rescue Chris Redfield and Zachary Anders.

The group eventually defeated Marshall and his goons, saving Chris Redfield but (supposedly) losing Zachary, as Marshall shot him in the head. But the man had nothing but a warning for them in the form of a song, saying that in the end, Sven Waternaux would destroy the multiverse. He also added that MILE was an organization from the future sent to stop Sven before he got to the point where he could not be stopped, and that he himself would return later in their journeys.

His promise was kept, and in the Second ES Saga, he returned to the group as an IA Senator.
