I find this information by message wall of Elmenhilde Lover: Melvozoa is confirmed to be more powerful than Great Red and Ophis in their primes. Its powers are Reincarnation, Manipulating Parallel Worlds and itself in those worlds by altering their concepts, Time Manipulation, and the ability to Manipulate its own Existence. It is told that The Evil God Melvazoa has two evil god siblings. The onikami (evil god or fierce god) older brother, "Regaruzevua" and the evil spirit (Majin) imouto 'Sera Serubezu'. They are said to have lesser strength than Melvazoa. If those 3 arrive, the world will be destroyed. Kanzaki says that this'll happen in 30 years. Issei must surpass Dragon God in 30 years.
