unlike shiki, we can see Z having real old age breathing problems. also, he collapses for the tiredness. I think in the end he fight over his physical strenght, as WB and dead killed by no one, but just exhausted.

the first endpoint was protected by the marine base itself. the other two... mah!

in the end you can see Zephyr just didn't wished to kill his own subordinates, then he probably never tought to an instant explosion like throwing the DSs in the vulcano.
