Channel Hop: In the Philippines, the English dub of Combattler V channel-hopped from RPN-9 in 1979, GMA-7 in 1982, IBC-13 in 1986, RPN-9 again in 1989, SBN-21 in 1993, and ABS-CBN-2 in 1996. The Tagalog dub, on the other hand, aired first on GMA-7 in 1999 then on Hero TV in 2006.
Keep Circulating the Tapes: The English dub of Combattler that first aired on RPN-9 in 1979 has been lost to time, with not even a clip available online.
Alongside Raideen, Combattler was involved in a very bizarre instance of the trope. Marvel Comics had indirectly licensed the "Combatra" [sic] name and likeness via Mattel's North American toyline, so their Shogun Warriors comic book series couldn't use any characters, plots, or settings from the show and invented a whole new premise.
No Export for You: Not released outside of Asia and Europe until May 2020 when Discotek announced that they're handling retail for the show in Blu-Ray.
Unfinished Dub: The Arabic dub only covered the first season. Middle Eastern fans who wanted to know what happened in the conclusion of the series had to resort to fansubs.
During pre-production, the robot that eventually became Combattler V was initially conceived as being a nine-piece mecha. This would ultimately be reduced to five in the final product.
Aoi Hyouma's name was originally meant to be Shun Nakajima.
Juzo Naniwa's name was originally meant to be Yutaro Higashiyama.
Working Title: One of the proposed names was Magnes V
Trivia
The robot's name is a portmanteau of Combine, Combat, and Battle, and the V is intended both as an abbreviation for Victory and in reference to the five component machines that form the robot as well as its five pilots.
Unlike with its successor Voltes V, where the letter "V" is regarded as a Roman numeral and pronounced as "five" (ファイブ) in English, the "V" in Combattler V is pronounced as "vee" (ブイ) instead.
This anime series featured the first "realistically" combining giant robot. In this case, Combattler V was five vehicles that combined into one giant robot in a way that can be duplicated by its toy merchandise.
The toys for this series (provided by Bandai) were so successful that they were included in Mattel's phenomenal Shogun Warriors toy line as well as Bandai America's popular Godaikin line. In the Shogun Warriors collection, Combattler V is renamed "Combatra".
In Shin Super Robot Wars, Combattler V first tag-teams with Voltes V and has done so ever since. It also appeared in the Alpha series, Advance, Reversal, Judgement, L and DD. Of all those games, Alphas 2 & 3 AND Advance are the only ones that had Combattler teaming up with both Voltes and Daimos. Poor Daimos.
