List of Fringe characters

This article lists the major and recurring fictional characters on the science fiction television series, Fringe, created by J. J. Abrams, Alex Kurtzman, and Roberto Orci.

In the overarching storyline for the five seasons of the show, several versions of the characters are introduced. Beginning in the second season, a parallel universe is revealed; many of the characters, portrayed by the same actors, exist simultaneously in the original and parallel realities. The fourth season is set in an alternate timeline, where original and parallel universes have evolved from different outcome at a certain point in their history, resulting in two more versions of the characters.

These character profiles describe the characters as they appear in the original universe, with universe differences noted separately.

The Other Universe version of Olivia Dunham, dubbed by the prime universe as Fauxlivia, is an agent of the alternate and more powerful Fringe division. As of the end of season 2, Fauxlivia is sent to the prime universe by Walternate, taking Olivia's place without the knowledge of the Bishops, and maintains a close relationship with Peter for unknown reasons; this ultimately puts stress on Olivia and Peter's own relationship. Eventually, she is brought back to the parallel world after completing her mission in the prime one. Fauxlivia has also been nicknamed, unofficially, Altivia, Alt-Olivia, Otherlivia, and Bolivia. In the episode "Immortality," Fauxlivia is revealed to be pregnant with Peter Bishop's child, which Walternate hopes to use to sway Peter back to the Other Universe. The alternate Olivia gives birth to a son in the episode "Bloodline". In the episode "6:02 AM EST" it is revealed that she has named the baby Henry. Walternate uses a sample of the baby's blood to activate the machine to destroy the other universe.

For several episodes, Torv also played a third role, that of Olivia possessed by the mind of William Bell, which has been dubbed "Bellivia" by reviewers. In this, she simulates Nimoy's raspy voice and mannerisms used in the portrayal of Bell.

The Other Universe version of Walter Bishop, nicknamed Walternate, is the United States Secretary of Defense, and directly oversees the alternate and more powerful Fringe division. He is the main antagonist of the third season. Walternate also serves as the immediate superior to the shapeshifters, with their leader—Thomas Jerome Newton—being extremely loyal and protective of him (possibly being friends). Walternate, making arrangements through Newton and other shapeshifters, successfully traveled to the prime universe, and was later brought to see Peter for the first time since he was taken by his counterpart. Walternate convinces Peter to return home to the Other Universe, though he later goes back, though not before Walternate appears to have Olivia replaced by her own counterpart, as part of an unknown plan regarding Peter.
