This is what happened to Doom AU joseph (Dunno what to call it! but this is 2016/Eternal equivalent), he was turned by the Mysterious Tyrant, however, instead of crumbling to their will, His passion and Rage rose like a Pheonix from the ground, causing old and New to "amalgamate", a Half-Souled Fighter to Save his own Universe from Being enslaved. Fighting tooth and nail

the name of the species is the "Amalgam."

again like last pic, this is Not Cannon To both Games

Doom is by Id software.
