Super Deformed Gundam or SD Gundam originated from a contributed illustration of a junior high school student from Nagoya by the name of Koji Yokoi to the "Model News" magazine that Bandai was issuing in the 1980s. The illustration is of a Gundam but with the weird proportion where the overall height of the Gundam is equal to 2 of its heads. This illustration interested the chief editor and so leading to Koji Yokoi serializing SD Gundam in 4 frame comics in "Model News".
The super deformed designs were suitable for capsule toys, and so they were first merchandised as small SD Gundam-shaped erasers as part of the Gashapon series SD Gundam World in 1985. Built with a hole so they could be skewered into a pencil, the series was a hit with Japanese schoolchildren, and the concept soon expanded to other forms of merchandising and media, including gunpla, manga, trading cards, anime and video games.
The popularity of SD Gundam was such that between the late '80s and early '90s, sales from the SD Gundam franchise far exceeded those of the rest of Gundam. And whereas Gundam pioneered the real robot branch of mecha anime, SD Gundam's more comical and exaggerated approach to the genre served to move it away from the ultra-realism that it was shifting towards in the '80s, and inspired a new flood of super-deformed robot shows the late '80s and early '90s such as Sunrise's Mashin Hero Wataru and Haō Taikei Ryū Knight, as well as video games such as the Super Robot Wars franchise.
Although the SD Gundam franchise initially started out featuring characters and mecha from the mainstream Gundam series, by the 1990s SD Gundam spawned numerous spin-off series, SD Gundam Sengokuden (Musha Gundam) which has a Japanese Warring States setting, SD Gundam Gaiden (Knight Gundam) which has a fantasy medieval setting and SD Command Chronicles which has a modern military style, and Superior Defender Gundam Force which combines elements from the former three, to name a few.
Recent depictions of SD Gundams now use a 3-head scale as opposed to the classic 2-head scale.
The SD Gundam designs were also used throughout the earlier Super Robot Wars games (up through SRW F and F Final, stopping at SRW Alpha for the PS1), as well as other similar crossover games, as can be seen by the pupils present in the eyes of the various Mobile Suits that appeared. From SRW Alpha and beyond, however, the eyes of Mobile Suits remain blank, though the robots themselves are still super-deformed (just as all mechs represented in typical SRW games are), they also adhere to the new 3-head scale.
Musha Gundam first appeared from a toy model comic titled Plamo-Kyoshiro. The popularity of the Musha Gundam series has led to the domination of Musha style Gundam dominating BB Senshi line.
Although the stories themselves are parody, SD Gundam models is a serious business. While regular Gundam model lines strive for realism by introducing High Grade, Master Grade, and Perfect Grade models, SD Gundam models are designed for (and sometimes by) the customization crowd. Many SD Gundam models are designed such that variations of the stock models, as seen by SD Gundam comics, can be made by using parts from other SD Gundam kits. Modifying SD models is very popular in Japan, more so than the full-sized counterparts. In addition to made-up robots contributed to SD Gundam comics, Bandai also held monthly contests for custom Gundam (usually Musha-based) models.
Some SD Gundam models can be combined into a non-SD unit, either by design or via customization. Alongside SD kits of standard Gundam mecha, each year usually offers a stand alone line (usually supported by a separate manga) with each of the kits sharing a common gimmick. As of early 2006, the current line are designed as combiners. Whilst each kit can build a Gundam with at least two forms, all of the kits are designed to double as part of a combined form in various ways.

In Japan, SD Gundam comics was included in Bandai's BB Senshi Sangokuden plastic model kits, titled 'Comic World'. The popularity of SD series lead to stand-alone publications of SD Gundam comics, initially serialized in Comic Bom Bom by Kodansha. Comic World stories may contain different continuity from the expanded counterparts. G Beagle is only shown in Comic World format. In later BB Senshi kits, especially the musha-themed kits, contain side story for the separately published series.
Most of the SD Gundam manga were serialized in Kodansha's Comic Bom Bom with the exception of Musharetsuden ZERO which was serialized in Hobby Japan.
Some of the SD Gundam books are translated into Chinese and published by Rightman Publishing Ltd. in Hong Kong.
