Fucking finally. Elbaph is a physical being that was called the War God by Giants and he ate the Nidhogg fruit.
Very likely from Joyboy's era and fought Joyboy as Nika, since all D. and DF seem to hail from that time.
On one hand this closes the loop on one major thread, but it still leaves every other God referenced in Harley as unaddressed outside of Luffy's lol
Definitely not disappointed with this reveal though, Im glad Oda isnt ignoring War God Elbaph
