Thinking about God Serena again, and wondering about his other four unrevealed DS magics. We already know he has the four classical elements of Fire (Hellfire), Air, Water, and Earth, right? I thought it through a bit, and based on GS's personality, I think that the three of the Four unrevealed DS magics will be the following:

Adamantine/Diamond Dragon Slayer Magic: Reflects his prideful powerful status as one of the Spriggan 12, being as powerful, beautiful and nearly unbeatable like a diamond.

Star Dragon Slayer Magic: Reflects God Serena's flashy, flamboyant radiant personality, thinking he's the greatest star of them all.

Flower Dragon Slayer Magic: Even though girly, flowers may represent his androgynous style of appearance, especially with that ridiculous hair style of his, thinking to himself that he even looks good like that.

Can't figure out, however, what the fourth DS power could be. A safe bet would likely be Poison, but if I had to guess for something else, I'd say its a variant of Darkness, that being Eclipse.

If so, something like "Eclipse Dragon Slayer Magic" would fit his nature of wanting to overshadow everyone and everything and thinking he's the best of them all (until Acnologia comes around and rips him a brand new one that is)
