Episode 61: Forbidden Weapon

" Hiura: Saijyo, what's all this for ?
Saijyo: Of course it's the killing weapon against Chaos Header.
Musashi: This Hellzking will be...
Fubuki: The ultimate weapon against Chaos Header !"

―Team EYES upon witnessing Hellzking

After losing their patient over Team EYES on an Anti-Chaos Header project, the JADF secretly picked the remains of Hellzking and initiating Project H.B.. They also armed the robot with SOAAG (a moonstone that weakens Chaos Header) onto it's Hellzgun, which can annihilate everything. Sending the robot for a test, Hellzking is proven durable against laser turrets and rocket launchers and it fires the SOAAG beam, able to destroy an iron block with a weight of 113, 272 tons as they mock Cosmos for no longer being a match for Chaos Header. However, when he was sent away on a carrier, it starts moving as something wrong in the system. It seems that the Alien Beryl had already left a firewall on the system and that it causes Hellzking Revised activates on its own while making his way to town. Cosmos appears and transforms into Corona Mode. The giant fights Hellzking Revised but the robot fires the SOOAG Cannon. Though Cosmos dodges it, but it was powerful enough to evaporize a mountain. Hellzking Revised easily kicks Cosmos aside and overpowers him even in Eclipse Mode. A crack was revealed on the robot's throat and Fubuki decides to destroy the SOOAG stone but JADF Commander Sahara orders them to stop as Hellzking is the new weapon for humanity. Team EYES pays no attention and decides to help Cosmos by firing it's throat, giving the giant some time to charge Cosmium Beam and they finish the robot at once, leaving the SOOAG stone intact and producing a formula that can complete the SRC's Chaos Chimera mineral. General Saijyo furious over this but Commander Sahara didn't as he realise Musashi's words "Will those dirty hands will choose my neck ?".


  • Hellzking is in tribute to King Joe from the Ultraseven TV series and Heisei Ultra Seven OV series.
    • This similarity is played further as they are robots created by their respective aliens who tried to conquer Earth and once they rebuild by human under the assumption that they will become an ultimate weapon, they will still stick to their original programmings and attack the humans.
    • He is also in tribute to Deathfacer from Ultraman Tiga & Ultraman Dyna: Warriors of the Star of Light as they have the potential to kill their Ultra nemesis with their super deadly finishers.
  • The Hellzking Revised suit is a repaint of the original.
  • His roars are reused from Alien Standel Aborbas while as Hellzking Revised are from Chaos Clevergon.
  • Suit actor: Kazunori Yokoo (original), Toshio Miyake (Breaks)
