Silent Arrow is one of the unreleased toys from the second year of the Centurions toy line. It was featured in later episodes of the TV series. In universe, Silent Arrow is John Thunder's basic Assault Weapon System. Its major feature is a "power crossbow" that John wears on his back that looks like a giant bow. It launches a "pursuit arrow" that breaks apart in flight, revealing a net that captures villains. Silent Arrow also includes semi-automatic laser carbines, solar-energized chest armor, a solar reflective head shield, and a sonic vibro knife which is the only hand-held weapon in the Centurions' arsenal, although it can also attach to Exo Frames.
