Yeah it could be, maybe an implosion? Or an EMP?
I saw a fake spoiler for this chapter, maybe it was a Dark Abel or Jailer one on here ofc that said Kuma self destructed and he disabled the Goroseis regen somehow with it lol.
Given what Kuma can do with his devil fruit, he can do some insane shit with a self destruction potentially too, something more abstract and specific even?
Since S-Bear has his fruit too, Kuma will definitely die imo and Bonney will have S-Bear to live with her instead, which is all kinds of messed up but thats Oda for you. Kinda bittersweet too though, weirdly endearing.
I can see Kuma doing some kind of suicide move to protect Bonney, maybe he teleports her away and then tries to blow him and Saturn up? Or he teleports him and Saturn away to do so? Kuma having his Majinn Vegeta moment? Atlas being Chiaotzu vs Nappa here ironically?
We just need someone to get blown up by a "Saibaman" now too somehow too lmao. Someone to be the Yamcha even?:
