nik stop trolling
Do you believe "combined power of Marco, Vista, Crocodile, Izo and rest of commanders" are below than old dying WB?
That just means, Akainu came back, only to face a stronger group!! And managed to take out Curiel and ate Marco and Vista's attack like nothing
Meanwhile Whitebeard, post Akainu match, faced the same group that ran away from Akainu solo!! Whitebeard faced a weaker group than Akainu, and still ended up dying
if anything you should thank Oda for letting Whitebeard got killed by Teach and got a proper burial. Because if it was by Akainu, he would simply get evaporated in spot and there's no burial but a cremation!!
