@Salah WG you were right about 1083 being a crazy chapter and introduction of new villains with the Holy Knights
I was right about Last Two Chapters of this Volume introducing New Enemies
But it's not what i was referring to, i'm instead waiting for Man With Burn Scar Introduction, so i didn't count well
I believe that just like in Baratie, Chapter "Storm" came out 4 Chapters after Chapter "Before The Storm"
And then Following Chapter Introduced Mihawk (Chapter 50)
True Villain of Egghead Incident will be Introduced 5 Chapters after 1078
However, Oda stopped showing Egghead Events since that Chapter, so far it's only Side-Plots, which suggest that they don't count.
For my Next Estimation, i'd say Next Chapter is End of Mary Geoise Flashback & then we return to Egghead Events. We should have:
Chapter 1084 ---> Mary Geoise Flashback Continue
Chapter 1085 ---> Egghead Cast learn of Gorosei & Kizaru's Arrival
Chapter 1086 ---> Chapter that Focus on Saturn & some of his Backstory (Just Teaser)
Chapter 1087 ---> Man With Burn Scar is Teased once more as an Unstoppable Force
Chapter 1088 ---> Escape Chapter but They are interrupted by a Whirlpool
Chapter 1089 ---> Lurking Legend Full Introduction
However, these Numbers could change depending on how long Oda intends to show Outside Egghead
It's possible He will delay everything till Chapter 1100
(Which fits cuz this Lurking Legend is reason Dragon became a Revo who was Introduced in Chapter 100)
