Mecha-King Ghidorah (メカキングギドラ Meka Kingu Gidora) is a mechanically modified Ghidorah created by Toho that first appeared in the 1991 Godzilla film, Godzilla vs. King Ghidorah. After defeating King Ghidorah and sending it to the depths of the sea, Godzilla began to wreck havoc throughout Japan. Emmy Kano, a Futurian who rebelled against her crew, and M11, her android, were asked if King Ghidorah could be revived in the 23rd century. If possible, he could be brought back to the present and used as an anti-Godzilla weapon to protect Japan. Emmy and M11 agreed and went to the future using the time machine KIDS.
