Lol, Pedro is a SURE COMEBACK for me, Yasui not so much.. but who knows.. I wouldn't exclude it LOL... But Pedro? I'm telling you all, just you wait and see for yourselves!
And my reasoning for that are very simple honestly:
1- WCI arc, it had a full moon (where Carrot used her solung)... Same for Pekoms who is LESS IMPORTANT as character than Pedro.... he went Solung.... And we know for a fact that Pedro can control his solung form... because he TRAINED Carrot for it.... If Oda wanted Pedro dead...he would have revealed ALL OF PEDRO'S cards and arsenal before killing him..... meaning he would have gone Solung BEFORE dying to basically see EVERYTHING about him... hiding Pedro's solung form means Oda is DELAYING its appearance... otherwise it doesn't make sense... the SHs were in real pinch in that arc that Oda is giving all kinds of plotholes to make the SH escape... why wouldn't he make Pedro reveal a powerful form to help them BEFORE sacrifcing himself in a different event...
2- His connection to Bepo by having Zepo as partner NEVER BEEN BROUGHT UP... but Oda will have to make Pedro and Bepo have their moment about reminiscing Zepo
3- Sanji's words at the very end of the arc, where it feels like Sanji understood Pedro the most despite his sacrifice... Pedro sure is happy to sacrifice himself to let SH run... but Sanji hinted that "this was NOT your place of death" despite Pedro's own conviction of going to that island not intending to die... Reason is... Pedro's dream is explained to us as him wanting to be the bridge or the linchpin of the new dawn (which is by making the SH the bringer of the new dawn... escape from there)
HOWEVER, this is NOT HIS ORIGINAL DREAM... Pedro wanted to be PART OF that new dawn, which was hinted by those points:
- Him asking Roger to take him because he felt that he can accomplish it with Roger
- Him taking out his own eyes... trying to survive by any cost... to witness the new dawn
4- Lastly, and the BIGGEST CLUE for any One Piece character not dying yet... is we NEVER SAW THEIR BODIES... people should know better with this reason basically
that's on top of many CLUES AND HINTS that he's joining the SHs from "Foxy arc" where Luffy drew Pedro's crescent moon ear.... or the similarities/contrast Pedro shares with other crewmembers:
1- With Jinbe who is ex-captain of Sun Pirates/ while Pedro is ex-captain of "nox pirates" (Nox = night)
2- With Brook, who BOTH LOST 50 years of their life! Brook spent it ALONE.. Isolated... Pedro were stolen from him by BM
3- His style which matches Sanji...
Lastly, his position as a Lookout... which he did during their travels into WCI... also Jaguar is known for the "NIGHT VISION" ability
and lastly, the cover page which showed ALL PRESENT and FUTURE SHs as cats: it's our job to analyze which one is who!
There are some obvious ones like:
5 Chopper
1 Nami
2 Zoro
10 Jinbe
etc..
Number 11 is PEDRO FOR SURE... that is EXACTLY how Pedro's tail look like... just look it up
He's a future SH... and he RESONATED with Luffy 100 times more than Carrot... if he makes a comeback which he WILL... and Luffy sees him again... pretty sure Luffy will ask him to join him...
