Shaider's roll call
Dai Sawamura/Space Sheriff Shaider (沢村 大/宇宙刑事シャイダー Sawamura Dai/Uchū Keiji Shaidā?): A former archaeologist, he continued his astronomer father's research into studying the Nazca images and manages to track the meaning behind it from Peru to Easter Island. There, Dai uncovers an altar that knocks himself unconscious. Finding himself on Planet Bird, Dai becomes a Space Sheriff for managing to solve the missing. Eventually learning of the warrior Shaider and his presumed relation, Dai realizes his fate is to finish his ancestor's duty by putting an end to the Fuuma. When Fuuma managed to take over most of the Universe, Dai learns the altar is actually an entrance to where headless body of Kubilai was sealed along with Kubilai's weak point. Though sealed in by Poe with a limited amount of oxygen, Shaider manages to escape and fight his way through the Fushigi Castle to save Annie before fighting Kubilai and won against the fiend. With his mission on Earth over, Dai decides to take Annie around the world. When he transforms with the command Shouketsu (焼結 Shōketsu?, "Sinter"), the Vavilos envelops him with Blue Plasma Energy particles that form his armor within milliseconds. As Shaider, he uses the Laser Blade sword in his signature move Shaider Blue Flash or the Video Beam Gun in conjunction with Shaider Scope scanner to track down invisible foes. His own blues include, Shaider Punch, Shaider Kick, and Blue Flash Spark.

Behind the scenes


Dai Sawamura was portrayed by Hiroshi Tsuburaya (円谷 浩 Tsuburaya Hiroshi?), the grandson of Eiji Tsuburaya who created of the Ultra Series. Sadly, Tsuburaya died of liver cancer on July 24th, 2001 due to alcoholism developed through the years. He was 37 years old. When the Space Sheriffs returned in the 2006 video game, The Space Sheriff Spirits, Dai was voiced by Takuo Kawamura (川村拓央 Kawamura Takuo?).

As Shaider, his suit actors were Takanori Shibahara and Akira Shimizu.


  • In the IBC-13 and GMA dub in the Philippines, he is renamed as Alexis.
  • Sho Mikagami from the game, Evil Zone shares some similarities to Dai Sawamura as both men transforms into Shaider and Danzaiver respectively.
    • Both of their suits are completely different when they transform when Shaider's signature color is blue while Danzaiver is red.
    • Both men also shares their signature moves during battle against their enemies especially using their signature attacks to destroy enemies. In Danzaiver's case, he puts a battery to unleash a laser-like blade to make a heavy slash on his opponent.
  • In the Philippine Dub, he was voiced by two male voice actors in both broadcasting companies. In the ABS-CBN dub until it was replayed in both IBC-13 and GMA Network, Dai Sawamura is voiced by Tony Nierras and in GMA dub, he was voiced by Vincent Gutierrez.
  • In Zaido: Pulis Pangkalawakan, the late Marky Cielo who portrays as Alexis Lorenzo bears a strong resemblance to Dai Sawamura and as Shaider in both his casual and his metal hero form as his color motif is green.
    • Coincidentally, both actors who portrayed their main characters are also died in different causes; Hiroshi Tsuburaya dies from liver cancer on July 24, 2001 while Marky Cielo dies from his sleep on December 7, 2008 after his role in Zaido: Pulis Pangkalawakan.
