Just who do you think you are, showing your face here again. Impersonating my Father. Claiming this as your own. The nerve...
((I don't think Lucifer would be very accepting, and would feel very threatened/hostile towards your character. It isn't you! It's the fact that in his canon, God loved Lucifer most, he was the second angel ever created, the most beautiful (all of this can be found on Lucifer's profile.) So he feels that this is a false God, especially with how he spoke to Lucifer during his and Michael's battle, since God wanted the two to fight and it was one of his tests for them @_@))
