The Legend of Behemoth
According to legend, after the Mushroom Mages were chosen as the Mages, they were given a power to use if they were trapped in immobile forms. The power was to keep using magic and use hate to summon the God of Apocalyses.
The Luigi Era
Toadus and other Toads arrived in the area where the Mushroom Kingdom is today. After building the Toadus Castle, they began to have problems with the Mushroom Mages. Then Luigi came from the future and was hired by Toadus to get rid of the Mages. Luigi went around the kingdom with the Behemoth Wand and transformed the mages into artifacts. Then Luigi left for the future.
The God is Born
It was ten years after Luigi came around and the artifacts have overloaded with magic and hatered. The hatred and magic created the Mushroom Behemoth who began to destroy everything. All hope seemed lost until Donkey Kong came and Toadus gave him the Behemoth Wand and DK trapped the beast. Leaving the wand in the volcano of Yoshi's Island, he went back to the future.
The Kremlings found the Behemoth Wand and got crushed by the monster. So, Mario and the others summoned the Mushroom Mages and convinced them to help. After the Mushroom Behemoth's defeat, it was sealed in a box and the Mages left for the heavens.
The Mushroom Behemoth Appeared as the 7th boss in wario's story in super mario: mushroom behemoth's revenge.
