Now... everyone is actually wrong about this...
Lucifer goes outside of creation, with a hurt Micheal.
Then he just creates a big bang out of nowhere.
And... now he has his own universe. He also healed Micheal, it seems.
Now, who else has created a universe that easily?
Also, there was three universes in the Lucifer series.
Lucifer's, God's, and Elaine's (with Micheal's power).
Lucifer was trying to get Elaine used to her power, in those scans.
Also, as an add on to the Fenris/Lucifer fight.
She thought that Lucifer was powerless when he started the fight, but he had hid his power.
Lucifer didn't have wings, and he was also weakening from God not being there. The first attack he did, was blow Fenris's head off, and kill the immortal God of destruction.
