Moonfall: Robo Saga G Alpha is a project by the Humongous Mecha fans of the Troper IRC Channel. The moon is falling, and humanity's only hope is to gather the Power Crystals of twenty-six Humongous Mecha and combine their powers, allowing them to activate the Super Prototype Alpha-Machine. Unfortunately, there are different takes on what is the best way to gather the crystals. Particularly, the man who owns the I robot believes in the power of strength, and aims to get his hands on the 25 other crystals by force. In addition, not everyone is aware of the imminent threat posed by Moonfall and want to use the mecha for their own (good or bad) ends. The story opens as a young boy (Japanese, of course) stumbles upon G-Machine, thought destroyed, and gets embroiled in the chaos...
