Holiday is the primary character of Revolution 60, an assassin specializing in vehicular warfare. She's played by actress Jill Melanchon. She rides an experimental Chessboard motorcycle called, "Hyperion," a bike that uses graviton emitters in the tires to result in extreme speed and maneuverability. Her weapon of choice is the "Needler," a small semi-automatic pistol with similarities to a Gunblade.
Holiday is a gen 1 soldier of Chessboard. Though highly trained, she's lacking any of the genetic modifications modern recruits use. She sees anyone that's a "professional" as fair-game for wetworks, and feels no conscience whatsoever about killing them. But when ordered to kill anyone she considers a non-combatant, Holiday experiences extreme conflict.
Holiday is an excellent example of the unusually tall and skinny artstyle of series creator Brianna Wu. The ponytail on her head makes the shape of a heart, and she has four spiky strands of bangs that float in front of her.
