The Blackbird was an aircraft used by the X-Men in Earth-92131.
History
After receiving a call from Moira MacTaggert requesting help, Charles Xavier told Beast to prepare the Blackbird. The X-Men then flew to Muir Island aboard the ship.
After learning about Proteus, Xavier told Beast to take Rogue and Wolverine aboard the Blackbird and to see if they could track him.
Beast, Wolverine, and Rogue were aboard the Blackbird when they received a mayday regarding Proteus. At another point, the Blackbird took off from Muir Island, with Moira and Xavier aboard, alongside Beast, Wolverine, and Rogue. The ship soon landed near Proteus's location. After Proteus left, the Blackbird was flown after him, with Beast observing that his path seemed to lead to Edinburgh. (TV: Proteus (episode 1) [+]Loading...{"ep":"1","1":"Proteus (TV story)"})
