Kate Fletcher

Agent Katelyn Ann "Kate" Fletcher (ケイトリン・アン・「ケイト」・フレッチャ) is a main character in the first season of Ultimate. She is a time-traveler from the 22nd century, the daughter of Nora and Henry Fletcher, the fiancée of Alex Scott, the founder and former leader of the Legends, and a good friend of Marcus Allen.

After her family and Alex were murdered by Prometheus, Kate illegally traveled to the 21st century to find help and formed a team with Hunter Bradley/Arsenal, later known as the Legends. They found themselves in conflict with Helix and formed a bond with new member Marcus. Ultimately, she was able to help finally defeat Helix and kill Prometheus with the Anarchy Spear. Although fulfilling her mission, a new timeline began to set in, erasing Kate from existence.

In the new timeline, Kate's history as an agent of the International Time Corps remained the same, however, Alex and her parents were still alive. A few years later, Kate from the new timeline was brought by Ryan Harper to the 21st century for Malcolm Dark's Survival Games. Despite being confused and unfamiliar with the Legends, she helped them defeat the Legion and was returned to the future.
