Чтобы не дать ни одной из противоборствующих сторон решающего преимущества в войне, мини-конов на космическом корабле отправили в нашу Солнечную систему. Много миллионов лет они пребывали на Земле в деактивированном состоянии. Наконец, их нечаянно находят обычные ребята — Рэд Уайт, Карлос Лопес и Алексис Ти Данг, которые теперь вместе с мини-конами будут драться за их свободу и свою планету. Много веков назад началась грандиозная и беспощадная битва за господство во Вселенной между двумя расами супер-трансформеров - героическими Автоботами и злобными Дисептиконами. Их силы были примерно равны, и никто не мог одержать окончательной победы. Однако неожиданно в этой войне появилась третья сторона - «зеленая армада» трансформеров Мини-Конов, способных нарушить сложившееся равновесие сил.

Теперь исход сражения зависит от того, чьим союзником станут Мини-Коны. : Armada, known in Japan as Super Robot Life-Form : Legends of the Microns (超ロボット生命体トランスフォーマー マイクロン伝説, Chō Robotto Seimeitai Toransufōmā Maikuron Densetsu), is an anime series. It inspired two sequels, : Energon and : Cybertron. Hasbro handled the of the English license, while Takara handled the of the Japanese license. : Armada and both of its following series are all part of a saga known as the "Unicron Trilogy". : Armada was written and produced in Japan, with creative input from America (the Japanese the series as set in the G1 , but this idea was discarded by Hasbro, who also mandated the inclusion of Unicron, who had not been in the original story treatment for the series).

However, the show premiered on Cartoon Network's Toonami in America before its original Japanese had aired - the result of an schedule set by the network, which caused the series to be rushed out of . , Armada features a lot of animation (which would go on to be perfected for the completed Japanese episodes), and a hastily produced dub which features many errors in naming such as Sureshock being called "Grindor" in multiple episodes, Hot Shot being called "Hot Rod", and Optimus's Mini-Con partner Sparkplug being called "Leader-1" (the same name as Megatron's Mini-Con), as well as and dialogue which does not match the action onscreen. When Armada was released on DVD in Japan, each of the thirteen volumes came with a four-page mini-manga and an exclusive repainted Mini-Con figure. The manga, titled Tales of the Microns: Linkage, feature these repaints in an original story which served to fill in many of the blank spots and plot holes in the animated series. .
