Tsunami? Not much of a threat shouldn't it? Considering Aokiji can just freeze it and god knows what Akainu can do!!

luffy is very famous even among whitebeard

It's probably another pacifista, killing off Kuma's character all of the sudden doesn't seem to suit Oda's style. There's so much to learn about his past relationship with the revolutionary army.

i'd say he's more of a general.
seems like he's trying to play strategy games with sengoku.
this is awesome!
even gear 2 luffy still cannot defeat smoker.
i think he's way too strong for his rank.
oh and btw he's not a captain.
first he is introduced as a colonel then after alabasta arc he got promoted into commodore.
there's still a lot of mystery surrounding kuma. i think it's still too early to be sure of his story. but maybe what flamingo means is something like kuma is already dead a long time ago and his remains were used by vegapunk to construct the present cyborg-kuma. so the kuma luffy met at shabondy is not even the real kuma to begin with. shabondy kuma and the present kuma is still the same i suppose, but it's not the same kuma ivankov used to know. because the real kuma is used to be known as a violent tyrant but the shichibukai kuma is the most obedient shichibukai to the WG.

i think theres no problem with a cyborg having more than one power since vegapunk can fuse DF power with an object. a cyborg/robot can be consisted of multiple of such objects imo. but i agree with the paw-paw kuma being real kuma's body that have been modified. but i think the paw-paw fruit is not the only difference from the PXs. paw kuma have a personality and can speak etc just like a real person while PXs are thoughtless robots. maybe he is brainwashed or sumthing.

but i don think kuma will let him "die" himself if he found out he will in trouble after helping strawhat...but maybe vegapunk got installed something inside kuma's body that can deactivate or something like tht?

well, just wait for next chapter bah
