Power Rangers S.P.D.

Cadets of Space Patrol Delta's Ranger Academy protect Earth from alien invasion in this futuristic action series. The excitement begins when the rangers go up against the evil alien Emperor Grumm and his battalion of Krybot cyborgs. When the A Squad disappears, it's up to the B Squad rookies to rescue them using their speed-of-light Zord transports, state-of-the-art weapons and, of course, good old-fashioned teamwork.
