IT'S GONNA TAKE A ROCKET PUNCH SCIENTIST TO FIGURE THIS OUT!
The most readily available sources of online information I could find to establish my chronology were the product assortment numbers off the boxes, the Mattel toy catalogs from 1977, 1979 and 1980 and my own collection of newspaper ads. I got product assortment numbers for almost the entire line just from pictures of Shogun Warriors toys on the Action Figure Archive and other various websites. The Mattel toy catalogs were over at Plaid Stallions and of course the newspaper ads come from my own Vintage Space Toaster Palace. I found each reference had its strengths and weaknesses. Assortment numbers were good for figuring out what waves of toys were grouped together but they didn't give dates of release. The toy catalogs showed what was scheduled for a certain year but didn't cover everything released and while the ads could definitively mark the dates certain figures were available, not every toy got ads. Once all these separate pieces of information came together the larger picture began emerging and although I still don't have it all I do have a better understanding of how the Shogun line evolved. Here then is the first half of my chronology of Shogun Warriors releases which encompasses 1977-1978. 1979-1980 will come later.
JM Fields 11/24/775 inch figures / Asst #2107
2107 5 inch assortment
The 5-inch Shogun Warriors assortment appears in ads and Mattel catalogs every year from 1977 to 1979. The 1979 Mattel toy catalog showed retailers could order either cases of the same individual figure or an assortment with a mix of all four. The standard numbering pattern for Shogun Warriors had the combined assortment assigned the highest number. The 5-inch figure assortment was never expanded beyond the initial 4 figures and did not appear in the 1980 Mattel catalog. In 1978 Mazinga's name would change to Great Mazinga on packaging but his number and assortment would remain identical to the 1977 release.
FedMart 10/11/77Giant 23 1/2 inch figures / Asst #9861
9861 Giant figure assortment
The first three giant figures were sold in individual case assortments and also in a mixed case. The 1977 Mattel catalog doesn't show a mixed assortment case number but it does appear in ads and it follows the standard numbering scheme where the mixed assortment gets the highest assigned number. Assortment 9861 lasted the entire life of the line but would see additions to and subtractions from this original lineup of three 23 1/2 inch tall figures. As with the five inchers, in 1978 Mazinga's name would change to Great Mazinga on the packaging but his number and assortment would remain identical to the 1977 release.
JM Fields 11/29/783 inch Collectors Series figures / Asst #2518
2516 Great Mazinga
2518 3 inch assortment
The mixed assortment 2518 was the only way to order the 3 inch Collectors Series figures, making them unique amongst Shogun Warriors assortments in that retailers could not order whole cases of the same robot. These toys are interesting because one blog claims the 3 inch line was "commissioned specifically by Mattel" and another states they were released "Late in the Shogun Warriors toy line life" which helps placing them in 1978. If true then this would make the 3 inch figures the only toys not based on pre-existing robot figures from Japan. I think it makes sense that Mattel would wait a year to order the creation of all new tooling once they were sure the brand sold well in 1977. I haven't totally discounted the possibility they were released in late '77 but I haven't found any proof of that. Since the assortment numbers did not change from year to year I'd say good proof of a '77 release would be any 3 inch package back that identifies Mazinga as just "Mazinga" and not "Great Mazinga". I don't know if that exists, though.
5 inch figures / Asst #2107
Same as 1977, with Mazinga's name changed to "Great Mazinga" on box
Kaufmans 12/01/78TWO-in-ONE Figures / Asst #2730
2730 TWO-in-ONE assortment
The TWO-in-ONE label was entirely a Mattel delineation as these robots were originally from the same Popy GA series as the 5 inch die cast Shoguns from assortment 2107. While 2107 never saw the addition of any figures, the TWO-in-ONES assortment 2730 would be expanded on in 1979. The packaging of these figures touted their ability to change into two separate forms but Dangard and Gaiking required the removal of significant parts to achieve a transformation. Raydeen is historically significant because he's often cited as the world's first true transforming robot toy, with a very minimal amount of parts removal required in his change from robot to bird.
Fred Meyer 12/10/78Shogun Vehicles / Assts #2522 & #2734
2520 Solar Saucer
2522 Vehicle assortment
2731 Shigcon Tank
2732 Shigcon Jet
2733 Sky Arrow
2734 Vehicle assortment
Of all the vehicles released in the Shogun Warriors line, I've only found ads featuring the ones from the 2522 and 2734 assortments. At the time I write this there is an eBay auction for a sealed case of Sky Arrows showing that some retailers did indeed order full cases of individual items instead of the mixed assortment cases. The 2734 assortment would see the addition of two more vehicles in 1979 but the 2522 assortment would stay fixed at three.
JM Fields 12/12/78Giant 23 1/2 inch figures / Asst #9861
9860 Great Mazinga
9861 Giant figure assortment
Two new giants joined the 9861 Giant figure assortment in 1978. The addition of Godzilla and Gaiking with product numbers in the 2440s showed how when Mattel would add new figures, the resulting new product numbers were very out of sequence from the rest of the numbers in the case assortments they were being added to. Godzilla was so popular he is often found in stand alone newspaper ads that make no mention of his status as a Shogun Warrior. The ad here illustrates how retailers would often confuse line art of the 5 inch Shoguns with art for the 23 1/2 inch ones, but the text of the ad clarifies that this is indeed a solicitation for all five giants.
2600 series Zargon and U-Combine Combatra
Zargon and the Combatra U-Combine vehicles are numbered very differently from the other existing Shogun Warriors assortments and their product designations are close enough sequentially that I am grouping them together here. Although I have no proof in the form of newspaper ads or catalogs to show Combatra was a 1978 release, I figure the product numbers being in the same range of Zargon at least circumstantially supports a connection and I know Zargon was released in '78. That I have only ever seen Zargon in Sears ads makes me think he may have been exclusive to that store and if so I further suspect that the 2600 series product numbers may all be store exclusives.
Sears 10/03/782617 Zargon (also has 59497/59598 printed on the box)
U-Combine Combatra asst #????
2620 #1 Battle Jet
2621 #2 Battle Clasher
2622 #3 Battle Tank
2623 #4 Battle Marine
2624 #5 Battle Craft
2625 Deluxe Set
Like Zargon, the Combatra U-Combine vehicles don't have assortment numbers printed on the packages so I haven't been able to figure out how they were ordered from Mattel. I've only been able to find websites with pictures clear enough to get product numbers for the Battle Jet, Battle Clasher, Battle Tank and Battle Craft but I was able to discern a pattern so I've guessed at the numbers for the Battle Marine. I haven't seen pictures clear enough to figure out the product number for the Deluxe Set and whether or not that had a separate assortment number. [UPDATE! Thanks to Ed from Robot-Japan I figured out the Combatra giftset is #2625.] The small gap in sequence numbers between Zargon's 2617 and the first U-Combine vehicle at 2620 make me wonder if there are other figures that exist numbered 2618 and 2619. The Combatra U-Combine packages are so radically unlike any other Shogun Warrior packaging in their design that I almost thought they were foreign releases, but they have printed notices that they conform to PS 72-76, which is a US product safety standard. Their different packaging also supports my suspicion that they were possibly a retailer exclusive but I've never seen ads for them so I don't even know what store that could possibly be. [UPDATE! I have since found quite a few ads for Combatra vehicles from a number of different retailers.]
NEXT TIME: In the conclusion to my Shogun Warrior chronology I'll cover the fascinating sequence of 1979 additions to the product assortments and what the numbers say about possibility of a US released Jumbo Grandizer and TWO-in-ONE of that character as well.
