Brave Command Dagwon (勇者指令ダグオン) is a Japanese anime series begun in 1996, created and produced by Sunrise under the direction of Tomomi Mochizuki (who also wrote episodes for the show under the penname Go Sakamoto) and was the seventh and penultimate entry in the Brave (Yūsha) franchise.
Earth is the target of the former Sargasso prisoners who seize control of Sargasso and attack our planet - to counter this, alien officer Brave Alien selects five (and then later seven as the series progresses) teenage boys from Earth to receive the wrist-worn DagCommanders that transform them into the series' title team, the human equivalent to "brave" warriors.
Drawing inspiration from anime franchises which feature transforming heroes as well as anime stock footage hero transformation sequences like live-action tokusatsu franchises (e.g. Super Sentai and its Western counterpart Power Rangers), the selected teenage protagonists transform into special DagTector (ダグテクター) battle suits, by activating their DagCommanders' transformation function with the transformation call "Try Dagwon", which grant them pseudo-elemental powers and attacks as well as protection, weapons, tools and amplified physical power. If that is not enough, they have personal basic mecha at their disposal which can turn into humanoid forms as a part of Fusion Combination (融合合体), a process that sees a character (hero, villain, or otherwise) merge with their mecha not in the sense of a physical merger but in a style where the character transforms their body into anti-matter, like they became an illusion or ghost, and becomes an embodiment for their mecha's humanoid transformation, the mecha serving also as a way of assuming a mecha form. If even greater power is needed, the heroes can merge with additional support units (or perhaps each other) to strengthen their Fusion Combination transformations by forming a physical mecha combination.
