"Warning to Grid Battleforce! A dangerous criminal is on his way to Earth from across the galaxy. His name is Ryjack. His mission is to steal valuables from your Vault. Ryjack is armed and dangerous."
―Captain Chaku's message to Grid Battleforce Rangers warning.[src]

Captain Chaku is a force of justice throughout the universe; an intergalactic police officer, who appeared in Power Rangers Beast Morphers.


Captain Chaku is known for his work in the G5 Galaxy police force and hunting down space criminals. He comes to Earth in 2020 to destroy an intergalactic criminal called Ryjack. He first sends a message to Grid Battleforce warning them of Ryjack. Captain Chaku is first seen by the Grid Battleforce when he comes to Earth, chasing Ryjack and Grid Battleforce picked up on his alien bio-signature. Because Chaku is unable to speak English and communicates only in gibberish however, they mistake Chaku for Ryjack and attack him. They hold him at gunpoint with their Beast-X Blasters and Strike Morphers before he tries to go for his tracker but they shopt him down and Devon tries to apprehend him but Chaku teleports away.

Later, whilst the Rangers are investigating an alarm, Chaku teleports into Betty and Ben Burke's lab and watches them leave. However, he is intercepted before he can touch anything in the vault (seeing as the alarm is to indicate that he is breaking into the vault) although the Rangers have to leave to fight Ryjack and the resurrected Vargoyle. However, during that battle, they learn who Ryjack really is and go to his cell (minus Zoey and Ravi who have been poisoned by Ryjack). He then introduces himself and reveals that he was actually using the Morph-X to refuel himself after running out of power pursuing Ryjack. He gives them the formula to save Zoey and Ravi's lives but Vargoyle and a new Gigadrone are detected heading for different Morph-X Towers so Nate and Steel deal with the Gigadrone whilst Chaku and Devon go after Vargoyle. They meet him and some Tronics in combat in an underground parking lot and fight until Devon breaks Vargoyle's Compliance Collar using his Beast-X Saber. As Vargoyle flees, Chaku destroys the rest of the Tronics with his Enforcer Laser before summoning his Galactic Interceptor whilst Devon rides Cruise in bike mode. They briefly fight Vargoyle on vehicles before Chaku tackles Vargoyle off of his bike and they engage in a short duel which Chaku wins with his Enforcer Laser which disarms Vargoyle. They then kill Vargoyle for good with a combination of his Enforcer Strike and Devon's Beast-X Slash. Later on, back at Grid Battleforce, Chaku decides to team-up with the Rangers to bring down Ryjack for good. Tvicon.png TV STORY-Intruder Alert!

Captain Chaku is invited to join Grid Battleforce by Commander Shaw and the Rangers. Nate soon discovers that Chaku has a young daughter named Starlight, and that he is in fact a cyborg. He's unwilling to remove his helmet and let her see his face, out of the fear that she won't accept him.  Eventually, he and the Rangers succeed in destroying Ryjack and Chaku retires from the G5 Galaxy police. Nate uses the machine used to create the Rangers and Steel to make Chaku completely human once again.  After this, he thanks them and returns home to Starlight. However, he leaves behind a man-eating plant that initially tries to devour Ben and Betty.  They decide to use it as a trash eater but it has a bad habit of regurgitating slimy mucus.

Behind the Scenes



to be added


  • Chaku's name came from his Sentai and Metal Hero counterpart's transformation command, "Jouchaku" (蒸着 Jōchaku, Electroplate).
    • Although Captain Chaku's suit is based on Space Sheriff Gavan Type G, there are still minor differences in the suit used in original footage, mainly the colored lights on the helmet that matches Retsu Ichijouji.


  • According to a tweet from Jason Bischoff, Chaku was going to have a "hero name": the Silver Senturion. Jason wanted Chaku to have a connection to the Blue Senturion, but that idea didn't make it to the final script of "Intruder Alert!".
