Zona Fantasma
Superman fashions the Phantom Zone technology into an arrow projectile which upon striking a victim will project them into the Phantom Zone. Roy Harper, the original Speedy, steals this arrow from Superman when the original Teen Titans are invited for a visit many years ago. Roy, however, never uses the arrow and passes it on to his replacement, Mia Dearden, who uses the arrow during the events of "Infinite Crisis" on Superboy-Prime. Unfortunately, he is too strong for even the Phantom Zone arrow, and manages to break out.
