Theory Oda has been holding out on Urouge because he’s supposed to reintroduce Enel

[Monkey D Theories]

I think Urouge is secretly working for Enel. That’s why he’s the only supernova yet to be featured.

Oda is waiting for the right moment to bring back Enel. imo either in Elbaf or the final war.

In Egghead, Zoro will probably beat Lucci, a former antagonist of Luffy’s. I think Oda will probably repeat this pattern with other SHs.

I see Jinbe beating Crocodile and Enel ultimately getting beat by Sanji whenever he returns.

Urouge doesn't work for anyone besides himself.

He really must have left an impression bc so many want him back despite being gone since long ago
