Will An Established Character Get Inducted Into The Gods Knights?
By the time Elbaph ends, the Gods Knights could be down three members. Sommers and Killingham feel like they will die to weaken Imu. Brook will probably find a way to help Gunko break her covenant, but she’ll live. Killing her after being a brainwashed servant for over 60 years feels a little harsh for Oda. Regardless, the Gods Knights will have some openings.
In One Piece, any time an established elite group (Schichibukai, Yonko, Marine Officers) has a shakeup, it will mostly be filled with a character that was already established.
Schichibukai: Law, Buggy, Blackbeard
Yonko: Buggy, Blackbeard, Luffy
Marines: Smoker got promoted to Vice Admiral, Sakazuki got promoted to Fleet Admiral.
Even Garling was introduced as a God Knight before he got promoted to Gorosei.
I think the pattern will continue, and I have some names:
Doflamingo: Heavy favorite. CD bloodline, in WG custody, alludes to knowing some of the biggest secrets involving Imu. Strong enough where a covenant boost could put him on Zoro or Sanji’s level, even post Elbaph. Gorosei are probably aware he would try to betray them, but might be desperate enough to run that risk.
Mihawk: Dark horse. Mysterious character that has a lot of eerie visual similarities to Imu, which could be something. We know very little about his past, but maybe some of those early duels with Shanks took place in Mary Geoise when Shanks was a Devoted Blade? He is a loner (Cross Guild aside) who would probably view a covenant as cheating, but it would also put him in proximity to Zoro for their final showdown.
King: Outsider pick. Currently in WG custody and no captain. He‘s like Harald in that his rare bloodline might allow the GK to make an exception on letting someone from the outside become a GK. Depending on how Imu fares after Elbaph, he might want to keep a Lunarian body close as well. The WG do have the Seraphim, but King still has a lot of value, especially if he got a covenant boost.
