Kizaru probably was gonna take damage but turned into light, so that he
didn’t need to take damage , so that’s why Kizaru explodes onto the battlefield
Literally Kizaru would rather explode and destroy parts of Marineford than take damage, it’s possible he might have taken out fodder as casualties rather than take damage from Marco‘s kick
That’s how pathetic admirals are, sorry but that’s how it is
