There will be a duo of the old version and this version of Mettenna

This is Mettenna Meningoencephalitis. The true master of the Mettaurian Race and the true caretaker of the Mettaurs in the Network Transmission world. His mettaurs are his babies, and the Mettaurians are his family of brothers. For years he has led a massive empire across Africa, Middle East, and 1/2 of South America. He remains as the leader with the highest capacity of soldiers in his military. 75,000,000 Mettaurian troops, 7,000,000 Cano-dumb Cannons and other Real Life Cyber-Viruses like Magnet Bunnies, Champs and more, and 500,000,000,000 Mettaur Viruses in the Cyber World.

In 2013, he escaped the Cyber World, to begin his massive invasion across the Third Worlds, starting in Madagascar, hacking into military computers to spread and multiply his race, and soon, his pandemic has spread all across Africa, and then the Middle East, and then finally, Chille, Falkland Islands, Paraguay, Uruguay and made an alliance with a viral scientist named Dr. Herregods in Argentina.

By this day, the Mettaurian Empire remains the most dominant force in Africa, Middle East, and South America. Nexus Industries was also created in Argentina, Indonesia and secretly in the United States, to start a massive Cyber Warfare of 500 billion Mettaur Viruses, to take over the transmission world. It will soon be the most dominant force in the Cyber World.

As Mettenna may have escaped Megaman, he plans to have his revenge and to permanently destroy Megaman and his team, and to permanently delete their existence.
