The ability to induce a Big Bang like event to create a new universe or universal matter. Sub-power of Creation. Opposite to Big Crunch Inducement.
The user is able to create a Big Bang, starting a new universe or create a smaller one inside a pre-existing universe. They can condense the big bang into a type of energy blast capable of destroying an entire universe.
When Yahweh created them, Michael Demiurgos (DC/Vertigo) had the power to create from nothing, while his brother Samael could shape it to his will. Because of this, Michael has the power to induce big bangs whenever he needs to, making Yahweh's universe for him and then making Lucifer's universe eons later.
