So we have now two of the Old Maou Bloodlines with their specific Powers:

1. Beelzebub-> "King of Flies" which is summon, control and even transform into Flies

2. Leviathan-> "Sea Serpent Dragon Tail" transform into a Seas Serpent and Control Water (to a Higher degree as a Sitri it seems)

The Question will be what of Lucifer and Asmodeus.

For Lucifer i think about somethink like absolute Control over Demonic Power (even form Constructs and Weapons out of it) or Demonic Light or even Hell Fire (conjuring and controlling it, a little like Fiendfire from HP). For Asmodeus I don´t know. Maybe infusing Lust in other and control them through it (Lust doesn´t means sex....maybe lust for Battle or Lust for Revenge)

What are you thinking?
