Blocker Gundan 4 Machine Blaster
Japanese anime television series
Blocker Gundan 4 Machine Blaster (ブロッカー軍団IVマシーンブラスター, Burokkā Gundan IV Mashīn Burasutā) is an anime series that aired from 1976 to 1977 in Japan. There are 38 episodes aired at 25 minutes each. It is also known as "Blocker Army IV Machine Blaster", "Blocker Corps IV", "Blocker Army IV", "Blocker Corps", "Machine Blaster" and in Italian as "Astro Robot contatto Ypsilon" ("Blocker Corps IV Astrorobot" for the DVD release).
Plot summary
Earth is being attacked by the Mogul civilization, a super advanced people that live beneath the ocean. Professor Yuri, having studied the ancient super-technology in Astro base, anticipated such an invasion would take place. Using what he had learned of their technology, he created a team of four super robots, piloted by four youth pilots, to help repel the Mogul invasion, and they are known as the Machine Blaster Corps. Led by the pilot Ishida, the Blocker Corps stands firm against the attack of the Mogul rulers, Hellqueen V and Kaibuddha.
Concept
The number 4 comes from the team of 4 robots. The robots individually have their own weapon, but they can also be combined to form a fire ring which cuts through the enemies. It was not the most popular show since anime powerhouses Gaiking and Combattler V, which featured more creative combinations and designs, were ruling the airwaves.
This brief starts where responsible research should: with the source description of “Blocker Gundan 4 Machine Blaster” as japanese anime television series. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the arts & letters register because the source frames it as japanese anime television series. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Object files, edition statements, performance records and contemporary criticism preserve different stages of the work’s history. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q3627659. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1976 and 1977.
Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
