|This article is about a/an organization in Power Rangers S.P.D.|
Space Patrol Delta (S.P.D. for short) is an interplanetary police force that enforces laws over areas of space, using advanced technology to bring peace and order. S.P.D. also trains and deploys their own team of Power Rangers equipped with the latest possible advancements.
The original Space Patrol Delta was founded on Sirius at an unknown point in time, training Sirians and other aliens such as Icthior to be defenders of the galaxy. Prominent in their ranks was Anubis "Doggie" Cruger, who led S.P.D. when Sirius was invaded by the Troobian Empire under the rule of Emperor Gruumm, Mora (also known as Morgana) and General Benaag. Despite constant fighting and Cruger injuring Gruumm, S.P.D. was defeated and all Sirians (except Cruger who was presumed dead and his wife Isinia who was kidnapped by Benaag and Gruumm) were wiped out. Despite the fall of Sirius S.P.D. lived on in the form of other planetary branches and a Galaxy Command under Fowler Birdie.
One such branch, top-secret and known only to a select few was located on Earth in 2001 where Kat Manx, a top graduate of the S.P.D. Science Academy and several humans were performing experiments to develop morphers and other advancements for the organization. The effects become apparent when the human scientists' children displayed superhuman powers and other unique abilities; they were later split up to avoid repercussions. Cruger was reassigned to Earth and founded the local S.P.D. Academy in 2015 as well as watching over the scientists' children. Soon S.P.D. became a public organization with its own Power Rangers; S.P.D. Red Ranger Officer Tate was shown wearing a uniform identical to Time Force Red and later fell against Mirloc.
By 2025 S.P.D.'s Earth branch had two teams of Rangers: the reserve B-Squad Rangers and elite A-Squad Rangers; three of the original scientists' children joined the Academy and became part of B-Squad; under the Rangers it had cadets to be trained in the C-Squad and D-Squad. The organization now spans the galaxy with outposts located at Zantor, KO-35, Gamma 4, Gamma Orion, Verinox 12 and the Theta Quadrant among others. Despite this they are unable to stop the relentless march of the resurfacing Troobian Empire. Bridge Carson once stated (likely in exaggeration) that "Earth is the last place Gruumm hasn't conquered".
When the Troobians came to Earth the remaining children of the S.P.D. scientists are quickly drafted specifically into the B-Squad and later charged with Earth's protection when A-Squad is declared MIA after being sent to the Helix Nebula. Doggie himself joins the B-Squad after an assault by a returning Benaag, becoming the S.P.D. Shadow Ranger and Sam, one of the original scientists' children as well as the S.P.D. Omega Ranger arrives from a future timeline. The Troobians soon become entrenched on Earth though Gruumm is able to ensure the destruction of the Gamma 4 base despite this.
Eventually the Earth Delta Base comes under direct assault from the Krybot armies of Gruumm's weapons supplier Broodwing and many cadets and officers are defeated with the Base's defenses (especially its ability to become the Delta Command Megazord) being disabled in the process to draw out Broodwing and the Delta Squad Megazord is destroyed by the rogue A-Squad's Megazord. While the S.W.A.T. Megazord takes on the power of Gruumm's master Omni The Magnificence remaining S.P.D. personnel fight off another invasion, this time by Gruumm's full army until the arrival of reinforcements from Galaxy Command and the S.P.D. Nova Ranger also from the future turns the tide. Following this victory and Gruumm's ultimate defeat, Cruger is promoted and B-Squad is made the highest-ranking team on Earth with A-Squad disbanded.
Sometime later B-Squad Red Ranger Jack Landors abdicates his position to Officer Tate's son Schuyler "Sky" Tate, the B-Squad Blue Ranger; Birdie eventually retires leaving Cruger to become Supreme Commander, Sky to become the S.P.D. Deka Ranger and replace him as head of S.P.D.'s Earth branch and Bridge to become the Red Ranger.
In an alternate timeline on July 11th, 2025 the Troobians wiped out S.P.D. on Earth and conquered the planet with the help of Mora's friend Shorty and his brother Devastation. In response the remnants of S.P.D. developed the Omega Ranger technology and sent Sam back in time to avert the original defeat.
Blue Senturion held the title Defender of Intergalactic Law, Sledge searched for bounties and treasures, Sheriff Skyfire mentioned working for the Space Police and Captain Chaku served the police force of the G5 Galaxy.
Each S.P.D. Ranger (with the exception of Kat) has a numerical designation on their Ranger suits:
S.P.D. Red is 1, S.P.D. Blue is 2, S.P.D. Green is 3, S.P.D. Yellow is 4, S.P.D. Pink is 5 and S.P.D. Shadow is 100; S.P.D. Omega has VI and S.P.D. Nova has M, presumably standing for 6 and 1000 respectively (It's possible S.P.D. uses Roman numerals in the future). Except for Shadow Ranger, every other Rangers have marks on their helmets above their visors corresponding with their numerical designations. Red has one, Blue has two, Green has three, Yellow has four, Pink has five and Omega has six; strangely enough Nova Ranger has eight.
