Another day, another MMPR announcement from Lionsgate, who via their official MMPR twitter feed, have revealed that Bill Hader will be providing the voice of Power Rangers robot Alpha 5!
In the Power Rangers universe Alpha 5 lives in the Command Centre with Zordon and assists the Rangers. He also attempts to know them better by wanting to spend time with them and learn things. He matured slightly as the series progressed, but always remained a naive, childlike assistant.
When Rita sent the Green Ranger to sabotage the Command Center, the evil Ranger slipped a CD into Alpha’s inner workings, unleashing a virus into the unwitting droid which caused him to convulse violently (as well as make his voice falter and warp). Though the removal of the disc seemed to provide Alpha some temporary relief, Billy had to repair Alpha’s circuitry in order to permanently remove the virus. Alpha later captured the Green Ranger in a forcefield, but Rita rescued him before Alpha could reveal his identity (though the computer locked-on to his bio-signals, running them through the system and thus allowing everyone to know Green Ranger’s identity later) . It was after this that he successfully made reconnection with Zordon after he was lost in his timewarp from the earlier attack.
When Zordon sent him to retrieve the Singing Squash for Kimberly and Billy who have transformed into punks by a potion of Baboo’s slipped into their drinks, he encountered the Putty Patrol luckily he activated his internal defenses and with the help of the squash disabled the putties and escaped.
In the second season of Mighty Morphin Power Rangers, Alpha had three encounters with Lord Zedd’s forces. In The Wannabe Ranger, he attempted to assist a little boy lost in Angel Grove Park, but was attacked by the Primator, a shapeshifting gorilla monster who disguised himself as Billy and tried to trick Alpha into taking him to the Command Center. Alpha activated his self-destruct sequence to protect the Command Center, but seemed unable to deactivate it once the Primator left, and it was necessary for the Rangers do so. Later in the season, he would leave the Command Center to rescue the now-regressed Rangers, who had been trapped within a photograph by the Photomare monster after being regressed into children. In his attempt to capture the photo, Alpha was confronted by both Photomare and Goldar, but he was able to freeze both villains with a device of his and escape.
Near the end of the season, in The Wedding, he was ambushed by Finster and the Putties as he took a hike outside the Command Center. Just as the Green Ranger had, Finster inserted a disc into Alpha’s circuits, but instead of delivering a virus, this CD warped Alpha’s personality into an evil, obnoxious brat, who assisted Zedd and Rita by tricking the Rangers into an abandoned theater (which Finster proceeded to fill with monsters). Alpha also cut the Rangers off from Zordon and the Thunderzords. When Zordon’s pleas for him to stop annoyed him, Alpha comically altered Zordon’s image (giving him hair and glasses) before shutting Zordon off and up completely. Billy eventually removed the disc from Alpha, instantly returning him to normal.
In the third season, it was revealed that Alpha was constructed on the planet Edenoi (located in the constellation Andromeda) by King Lexian, the grandfather of the Masked Rider. It was because of this connection that the Rangers were able to team up with the Rider against the forces of his foe, Count Dregon.
Alpha later saved the Command Center from destruction by defusing an implosion generator planted there by Rito and Goldar. Unfortunately, the duo’s second attempt was successful, and the Center was blown to pieces, an event which the Rangers feared Alpha didn’t survive.
Alpha was later shown to be alive and well within the secondary base, the Power Chamber. Now assisted by Billy, Alpha continued to serve the Rangers (now the Power Rangers Zeo) as they battled the Machine Empire. A brief encounter with the Cogs resulted badly for Alpha, being short-circuited by an electric shock from one of their spears.
By the time of Turbo: A Power Rangers Movie, Alpha had gained a new, streamlined body. His plating was much more reflective than before, and his lightning bolt was now an arrow pointing straight down (this body would be more commonly associated with Alpha 6).
When Zordon left for his home planet of Eltar (in Shift Into Turbo), Alpha went with him, saddened that he was leaving the Rangers behind. The two later briefly returned in Passing of the Torch, in which Tommy, Adam, Kat, and Tanya retired from their Ranger duties. In this episode, Alpha is shown in his original body. This episode would be his last appearance in the franchise.
Though he does not appear, in “The Robot Ranger”, Alpha is credited with helping build the robotic versions of the Turbo Rangers. This was the last time Alpha 5 was mentioned. The next time Eltar was mentioned, it was under attack by Dark Specter’s forces.
