Marcy's crossbow is a wrist-mounted range weapon that was owned by Marcy Wu during her time in Amphibia. It can fold its two limbs plus hide a bolt when not in use for mobility. Other than being able to shoot different crossbow bolts (such as a flaming bolt) with other types of improvise projectiles (hornet's stingers), the crossbow acts as an improvise grappling hook helps Marcy swing round for faster and smoother traveling to close destinations. It is usually mounted on her right forearm.
Background[]
After being made a chief ranger of the Newtopia Night Guard, Marcy was given a crossbow by her teammates: Javi, Kettle, and Femur. She used it whenever she went on missions & during battles. It was sometimes used to fire rope bolts to help her swing and zipline, but sometimes the rope would break due to the material to handle her weight.
Sometime after Marcy was put in a coma when she was impaled by King Andrias, the crossbow was left inside her bedroom. When Lady Olivia and General Yunan head out to rescue Marcy after defecting from King Andrias, the duo enters a secret doorway in her room that leads to the basement. Yunan spotted her crossbow and took it with her in case Marcy needed it. After destroying eyes that were projecting their fears, the last one was hard to reach. Yunan tossed the crossbow to Marcy which she used to destroy the last remaining eye.
The crossbow is later seen by Anne's tennis racket and Sasha's pink heron sword on the cliff where the girls went back home to Los Angeles, California, USA, Earth.
