Sam

Sam is the S.P.D. Omega Ranger from 2040.

Early Life
In 2001, Sam's parents worked with Kat Manx and the parents of the B-Squad Power Rangers in developing the Morphing Technology used in the S.P.D. Morphers. However, these experiments had side effects that, while they did not affect Kat, they did affect the B-Squad parents, mutating their offspring and resulting in the B-Squad Power Rangers and Sam receiving their Civilian Powers, various powers they can use unmorphed. Though most of the offspring who were born to the participants in this project were adults by 2025, Sam was the youngest born and still a child at the time he is first seen. Sometime during his childhood, his mother died in a tragic accident.

For his civilian power, Sam developed the ability to teleport objects. His powers were misunderstood by other children, however, and he was ostracized. His desperate search for friends led him to be manipulated by Mora and her newest creation Bugglesworth, who turned people into dolls for Mora to collect. While the other Rangers were quick to judge Sam poorly, Z realized that Sam was not evil and just wanted to fit in. Although it took a lot of convincing, Sam eventually agreed to stay with his new friend and the other Rangers at the S.P.D. Academy.

S.P.D.
In the year 2040, Sam is chosen by the last of S.P.D. to become the Omega Ranger and is charged with a special mission: traveling back through time to 2025 to stop the rogue Morgana from destroying the Rangers and eventually Earth, thus preventing the disaster that has befallen his world. He managed to arrive just after Katana returned to his time. However, passing through the time warp has heavily altered his human form, reducing him to a floating orb of pure energy. Due to this setback, his only remotely-human form is his Ranger form. As Kat Manx works to find a way to send him back to the future, he assists the B-Squad Rangers in their battle to save Earth.

Omega joined the B-Squad to prevent Emperor Grumm's invasion and brings with him a powerful array of futuristic equipment including the Uniforce Cycle, a Zord known as the Omegamax Cycle and the Omega Morpher, which allows him to perform various feats including temporal manipulation (Hyper Mode), strength increase (Muscle Mode), and Judgement Mode. His suit brandishes the Roman Numeral for six,"VI". Because of his true identity, he is also capable of the genetic power of teleportation.

When some friends of Piggy steals S.W.A.T. technology, Sam's technological advancements are outmatched, but as the force from the future, he is always at the Rangers disposal when they need him.

During the final battle against Grumm, Sam's old friend Nova Ranger comes looking for him. After the battle is over (and with Sam apparently able to power down), the two of them return to the future.

Power Rangers Ultimate Alliance
Sam is later called upon to the Abyss of Evil from the future to stop the villains from drilling into the surface. He can still change into the S.P.D. Omega Ranger, though this time he can power down to human form. He also meets his younger and present-day self: Young Sam.
