Prologue: New Alienizer?
On planet Leslie, home planet of SPD officer Mary Gold/DekaGold, there was trouble. At night, there was a city in ruins, littered with bodies. Standing among the bodies was a mysterious creature that had its foot pressed down on the chest of the greatly injured Mary Gold/DekaGold. The creature was about to finish off Mary and move on until it got pelted with shots.
"You bastard! Get away from Mary!"
The creature turned its head to see the armed S.P.D. Fire Squad, which was an elite team in Special Police Dekaranger, composed of DekaReds.
"RAAAAAAAGH!" the creature roared, getting off of Mary before charging at the elite team.
S.P.D. Fire Squad presented their Transformation I.D. SP Licenses (Fire Squad ver.).
"Change Standby!" S.P.D. Fire Squad first slid the switch on the side of their respective Licenses to the top. They then did a transformation pose, chanting out the transformation call, "Emergency! Dekaranger!" They then pressed the button on the top of their respective licenses to transform.
S.P.D. Fire Squad had transformed into their DekaSuits before they used their respective weapons to fire on the charging monster.
