Collateral will always happen, Kizarus lasers against Sentomaru also destroyed the surroundings,etc
And yeah Luffy knows this is Vegapunks island what are you talking about?
The point is hes not going to try to destroy it but collateral will always happen.
And what is Luffys mission? To keep Kizaru away from Vegapunk and the Straw hats and keep them safe, Kizaru failed his mission in that regard because Luffy immobilized him but Luffy failed overall as well because Saturn and the marines are still there and Kizaru had the time to recover and get up.
It would be a good fight, because then Luffy will not have to run after him for like 80% of the fight and exhaust himself.
Is it? Most of Kizarus attacks did nothing to Luffy. Youre also failing to take into account the opposite, what if Luffy wanted to put down Kizaru at all costs and was bloodlusted? How many named attacks can Kizaru take? You realize Luffy speedblitzed Kizaru with WSG right?
Oh no it was hot, he ate it anyways and kept going just fine lmao. Jesus Lee. Want me to bring up the WSG panel again? That was the only thing ressembling an intent to put Kizaru down and it laid him out immobile for a while. Now Imagine he lands that mid fight, there would be follow up against a Kizaru that cannot move.
Basically your point makes no sense, youre only looking at what Kizaru can offer and not Luffy. Youre looking at what Kizaru can do if he is focused on putting Luffy down but not Luffy.
