History
The Weapon M is a weapon designed by Moira MacTaggert in order to travel back in time back to her first life and ensure she always wins.
After Orbis Stellaris wiped out everyone on the planet, Moira managed to survive and designed the Weapon M in a desperate attempt to go back to her first life. She killed Omega Red and harvested his Carbonadium coil. She harvested Logan's corpse for his adamantium coated femur, which she used as the base of the axe. She severed Xorn's head in order to use his black hole powers to cut through time and space and she finally harvested Gentle's corpse and removed his vibranium tattoos, which she used to bind the Weapon's components together. The last piece she needed was a piece of Mysterium, which she managed to procure when the X-Men came looking for a human Moira throughout the timelines created by the Moira Engine.[1]
