Nintendo DS 2006 is a mecha video game published by Nintendo only in Japan. Popular Japanese singer and voice actor Ichirou Mizuki sung its song heard in the game's Japanese television commercials and trailer.

The player uses the stylus to manipulate a Marionation Gear (MG) on the battlefield. MGs are giant mechas that have been developed from marionettes. The touch screen shows a control panel which varies depending on which MG the player is operating. Actions are performed using the touch screen. They include shooting, jumping, swinging a mecha's arm or close-range weapon, changing form, shooting projectiles, etc. There are more than 100 mechas, some of which are able to transform from a vehicle form to a robot form and vice versa, similar to piloted robots from many Japanese television shows.

The gameplay of Chōsōjū Mecha MG is split into a series of over 120 missions, which can range from defeating enemy robots to winning first place in a race. Outside of battle, MGs can be purchased from various shops, and equipped with status boosting items.

In the 2008 crossover fighting game, Super Smash Bros. Brawl, 3 Marionation Gears, which are the Warrior Mech Gauss, HM Mech Rosa, and Musketeer Daltania, appear as trophies and stickers. The Beetle-like MG, Ningyou Kouchuu Viigaru, appears only as a sticker in Brawl. A remix titled "Marionation Gear" plays on a stage called Norfair, which is an area from the Metroid series, in Brawl. "Marionation Gear" returns in Super Smash Bros. for Wii U on the same stage. Gauss also appears as a spirit in Super Smash Bros. Ultimate, with the song "Marionation Gear" returning as well, but this time it can only be played in stages not associated to any fighter.
