Professor Nicholas "Nick" Cutter
Cutter is the team founder. His wife Helen disappeared eight years before he saw the first anomaly, at which he met with four other people, and they became his team. Timelines changed after Cutter came back through an anomaly, and Claudia Brown, his love interest, no longer existed. James Lester and his best friend Stephen thought he was crazy, but Cutter came to live with it, even though a new member of the team, Jenny Lewis, was identical in every way. Cutter faced many more creatures, and encounters with humans as well, before being shot in the ARC fire by Helen. That wasn’t the end of Cutter. Timelines changed back, and he never died. Plus, Claudia returned. Cutter is determined yet has a heart, as he still tries to reason with Helen despite all she’s done to him.
