Marshall is an C shapeshifter type, not able to change his digitals or eye patterns, or height. He was a lonely child. His father hated him the most for killing his mother, even though that was not true. When he was 12, he already knew what to do: he would work for the CCI and avoid that other children gone through what he had gone: home violence. But years came and gone, and the wound was still open. They sent him to rescuing and tracking missions due his hability of finding things and going undercover. He, then, found Jane out in the woods and felt really attracted to her, but did not knew she was, in fact, his target. When he discovered, he found himself heavily delusioned. He observed her in silence during all the time she was under CCI domain. He knew she was rebelling against the organization that rescued him and, yet, did nothing to stop her. When she escaped again and left him behind, even though she did not really knew he was there for her, he felt delusioned again, and full of vengeance. He is jealous of Ollie, who is 24/7 by her side, and childishly declared him his enemy, although Marshall did not even knew why was that.
