Characters: Sliders

Quinn Mallory (Jerry O'Connell)

  • Basement-Dweller: He still lived with his mother while finishing college. He still had his own room, but converted his basement into a makeshift laboratory and spent most of his free time down there.
  • Brilliant but Lazy: In the pilot, he passes up the chance to correctly answer a difficult question (despite Arturo yelling at him) because it didn't interest him. On the other hand, he took the time to read Arturo's papers that weren't assigned for class because their contents did.
  • I Just Want to Be Normal: He resented his intelligence for years because it made him different from everyone else. (Being skipped ahead and thus smaller than his classmates didn't help.)
  • Meaningful Name: Quinn is Irish for "wisdom, reason, intelligence" and Mallory means "unlucky." Pretty fitting for a smart guy who ends up being merged with his Alternate Universe duplicate.
  • The Nth Doctor: Played by Jerry O'Connell for the first four seasons, then briefly by an unknown actor in the Season 5 premiere before being replaced by Mallory.
  • Really Gets Around: Had Ship Teases with Wade and Maggie, as well as plenty of one-off love interests.
  • Team Dad: Becomes this after Arturo dies in late Season 3. Lampshaded in "Slither," where Quinn laments that, without Arturo, "It's all on me, and I'm flying blind."

Wade Welles (Sabrina Lloyd)

  • Alliterative Name: Wade Welles.
  • Back for the Dead: In "Requiem."
  • Break the Cutie: Three years of sliding takes a toll on her; Arturo's death is the moment that finally breaks her.
    You know, when I first started sliding, all I saw was adventure. Now all I seem to see is death.
  • Devoted to You: EVERY male character in EVERY dimension falls in love with her.

Rembrandt Brown (Cleavant Derricks)

  • Conspiracy Theorist: "The Return of Maggie Beckett" reveals that Remmy always believed aliens landed at Roswell.

Maximillian Arturo (John Rhys-Davies)

  • Catch Phrase: The number of times he called someone a "blistering idiot" and yelled "Incoming!" at the end of a slide borders on this.
  • Deadpan Snarker: Tends to react to things around him with either blustering anger or dry sarcasm. One example from the pilot, where everyone's shock at finding themselves in a Soviet-dominated parallel America is interrupted by the Professor's desire for lunch:
    Quinn: Professor, how can you eat at a time like this?!
    Arturo: My stomach has no political preference.
  • Disappeared Dad: According to "Into the Mystic," he's actually this to someone back home.
  • Hidden Depths: Lampshaded in "Eggheads," as he talks about his dead wife and how encountering her double is stirring old feelings.
    Wade: I had no idea that you were such a romantic.
    Arturo: And I had no idea that I would have the opportunity.
  • I Just Want to Be Special: Season 2 introduced the idea that he resented Quinn for inventing sliding by accident.
    You resent the boy because it comes so easily to him.
  • Jerk with a Heart of Gold: But virtually every single double encountered was a Jerkass.
  • Last Name Basis: If the others don't address him as "Professor," then they do this.
  • Missing Mom: According to "Season's Greedings," his mother died during a World War II bombing. While Word of God confirms that the Arturo that said this was the double from "Post Traumatic Slide Syndrome," their two worlds were described as so similar that the real Arturo likely experienced similar events.
  • Redemption Equals Death: See Spot the Imposter below. The unscrupulous fake Arturo from "Post-Traumatic Slide Syndrome" ended up taking a bullet for Quinn.
  • Secretly Dying: Introduced in "The Guardian," where Quinn finds out and is sworn to secrecy. Rembrandt would find out in "The Last of Eden."
  • So Proud of You: He's not one to get emotional, but his admiration for Quinn always came through.
    Every teacher goes through life hoping just once he'll have a student like you.
  • Spot the Imposter: In "Post-Traumatic Slide Syndrome," the Sliders find themselves faced with two Arturoes each claiming to be theirs. The Sliders themselves have trouble figuring out who is who and Word of God ultimately confirmed what fans long suspected: the wrong one slid with them.

Maggie Beckett (Kari Wuhrer)

  • Daddy Issues: Highlighted in "The Return of Maggie Beckett."

Colin Mallory (Charlie O'Connell)

  • Fish out of Water: After spending most his life living in an Amish paradise, he has a little trouble adapting to more advanced universes for a while.
  • Gadgeteer Genius: He built his own hang glider, for one.
  • Put on a Bus to Hell: In "The Unstuck Man," Colin was made unstuck and left involuntarily sliding from one dimension to the next. At first, there was concern that Colin didn't survive, but he was generally treated as still alive and in need of help. By the end of the season, however, the characters acknowledged that Colin may really be dead, but it was nonetheless left ambiguous.
  • Smarter Than You Look: Colin is rather naive, but only because he came from a less advanced world. He is nonetheless quite intelligent, adapting rather well to modern technology and figuring things out for himself.
  • Wide-Eyed Idealist: As seen in "California Reich" and "My Brother's Keeper."
    You don't hurt someone to help least you're not supposed to.

Quinn "Mallory" Mallory (Robert Floyd)

  • Applied Phlebotinum: Geiger's experiments and combining him with Quinn allowed Mallory to walk again.
  • Dark and Troubled Past: Including Parental Abandonment, a criminal past and suffering from muscular dystrophy.
  • Flip Personality: Mallory emerged as the dominant personality, but in "The Unstuck Man" and "Applied Physics," Quinn's personality and memories periodically broke through. By the end of "New Gods for Old," however, Mallory could no longer feel Quinn.
  • I Owe You My Life: He is weary of Dr. Geiger, but acknowledges that without him, he'd still be in a wheelchair.
  • Last Name Basis: Mainly because Maggie was incapable of calling him "Quinn," and then everybody picked it up. Even Diana, who knew him before Season 5's events.

Diana Davis (Tembi Locke)

  • Tomboy and Girly Girl: With Maggie. Diana is the Girly Girl of the pair, taking Wade's place in Season 5.
