Bogey is a shoe in, but Kuma would only join as the ships guardian while Chopper/Franky/Vegapunk/S-Bear try fixing him.
I doubt theyll get to do something so nice for Kuma, mans dead.
i think they might still have a chance to save him, as Kuma shown he still alive there some where/even though he can't talk, and kuma sefless sacrifice and helping sh pre timeskip/plus his life. he deserver a chance of happyness.
for the point kuma is gone. i don't think so because oda showed this.
when went to rereading chapters, shows one of the clone/kuma stop attacking after see bonney transform back to kid(prob vegapunk/hidden memory put into robot kumas, after he made deal with the wg to never harm his daughter)
in following chapter time frame show kuma is still with us
when bonnie gets scared for real/traumatized by the bugs/vega punk knows her weakness as she said!? which could mean vega punk secretly manipulating bonney into awakening kuma in the chain events...
as the bugs are summoned here. real fear/crying from bonney emotion is the trigger!
vega punk sus comment/about bugs, and bonney fear= could mean bonney was scared of saturn/if she saw him in bug form, as hinted. about saturn giving the commend to erase her father memories/when she came here years ago......
next after bonney faints/fear level high ,kuma is suddenly alerted/father mode activated. this man is not all lost!!!
perhaps with his damaged body/he getting signals/like a baby monitor vega punk could design, linked with bonney emotion/level like fear/scared/hurt level.(chip level, how ever it works) Wg already gonna break there promise and kill bonney anyways
as we see kuma rushes to the last location where bonney was back at MG, (could be signal/data delay because of his damage body) after he makes it there, he looking around rushing, and encounter akainu, who ask him why he here, akainu has flash back of bonney saying her father would never leave her behind!!
after this Kuma rushes away(teleports) he is following the signal where his daughter was!!
next probably the area where sh found bonney almost drowning.. then next egg head! (so many danger signals/stress level from bonney kuma picking up)
as current events Saturn about to kill her
could be luffy punches saturn away, or Kuma enraged father incoming which looks like the case!!! showing us he still not dead!! and can be saved by bonney!!
so depending how story goes
1.kuma show up, before saturn kills bonney...which looks like high chance.. making it more impact/emotion to everyone saying kuma is lost/a walking corps.....
2.luffy gets enrage and saves bonney
3. bonney after experiencing the memories ages up to that kuma/strength form and push saturn away
4.kizaru grows back bone and saves bonney while kuma still looking for his daughter
