In order to understand the ''Duel Masters'' franchise, one should be aware of how weird business relationship between two countries (in these case, US and Japan) working separately on the same product can get. One audience liking one product while the other hates it, localizations, etc. The thing goes like this:

In 1999, inspired by the success of ''Franchise/YuGiOh'' series, Creator/WizardsOfTheCoast licensed ''[[TabletopGame/MagicTheGathering Magic: The Gathering]]'' for a manga series called ''Duel Masters'' by Shigenobu Matsumoto. The company was not, however, entirely happy with Matsumoto's take on the concept (a series based on people ''playing'' Magic rather than one actually set in the fictional worlds of the game). For this reason, they never imported the manga to the US, and were reluctant to greenlight an anime. They worked around the problem by inventing a new card game also called "''TabletopGame/DuelMasters''"[[labelnote:*]]Referred to as Kaijudo in the show only[[/labelnote]], essentially ''"[[SelfPlagiarism Magic lite]]"'', to be used in the anime.

This [[Anime/DuelMasters new anime]] proved popular enough that [[RecursiveAdaptation a TCG was actually created after it]], again called "''Duel Masters''". Anything from the franchise from this point on, including later Japanese manga as well as American-created comic,) would use ''Duel Masters'' cards instead of ''Magic: The Gathering'' cards. This [[EarlyInstallmentWeirdness makes the mention of Magic weird to anyone unfamiliar with this franchise origin]].

When [[Anime/DuelMasters the anime]] and [[TabletopGame/DuelMasters card game]] were released in the U.S., Hasbro, the parent company of Wizards of the Coast, looked for a company to dub [[Anime/DuelMasters the anime]]. Somehow, they ended up choosing a dubbing company called Plastic Cow, previously best known for their ''Franchise/StarWars''-themed ''Series/{{COPS}}'' parody ''[[http://www.youtube.com/watch?v=4MMAoOPa0Pg TROOPS]]''. Originally featuring a serious, more straightforward plot, Plastic Cow's sense of humor permeated the dub process of the show, resulting in a GagDub, complete with edited scenes played for laughs establishing a completely different tone that the show would be known for in America.

That being said, some viewed it as a fresh change of pace in comparison to the dramatic nature of [[Anime/YuGiOh that certain other show about card games]]. In addition, this show tried the GagDub approach long before ''Anime/YuGiOhGX'' started [[http://www.dailymotion.com/video/x2bml9_is-littlekuriboh-writing-for-yu-gi_fun#.UbxvqfnqlEI lampshading itself]] and before ''WebVideo/YuGiOhTheAbridgedSeries'' was created, helping it built up a sizable fanbase.

Said popularity supposedly convinced the creators to produce an [[RegionalBonus American-only anime season]], set before the actual, Japanese second season, but its fame was not to last. [[MoneyDearBoy Hasbro started shopping around to other companies and demanding similar output at a lower cost]], which annoyed many employees. As a result, no two seasons had the same voice cast or dubbing studio; Elastic Media was brought in for said American-only season and Howling Cat (perhaps best known for their dub of the ''Anime/BattleBDaman'' anime) for the third (based on ''Duel Masters Charge'', the actual second season, but called "Duel Masters 2.0").

Afterward, the American version of the anime ceased to exist. The American version of the TCG, which by this point had changed the flavor text on newer cards to reflect the GagDub of the anime, followed soon after. [[NoExportForYou In Japan]], however, both the TCG and the anime series continues to be active, with the latter having over 10 seasons. Many things changed during its run, including being CGI animated (beginning with Duel Masters Zero and ending with Versus) and now being produced in high definition (beginning with Duel Masters Cross).

A new ContinuityReboot WesternAnimation series called ''[[{{WesternAnimation/Kaijudo}} Kaijudo: Rise of the Duel Masters]]'' was picked up by Creator/TheHub for the Summer 2012 season, [[InNameOnly with no connections to any of the original anime]]. It was based around ''{{TabletopGame/Kaijudo}}'', a completely different TCG still-still made by Wizards of the Coast), which wasn't compatible with the original ''TabletopGame/DuelMasters'' TCG.

(remember, the examples of each series goes on their respective pages)

* SelfPlagiarism: From ''Magic: The Gathering''.
* RegionalBonus / ForeignRemake: The original anime had an American-only "second season". Additionally, the franchise is now being rebooted in North America under a different name ("Kaijudo", a term that doesn't exist in the Japanese franchise) with no relation whatsoever to the original franchise, which is still ongoing in Japan.
