Okay as the title implies I gonna discuss about Kaidou..First of all how I said he was strange? First , he was captured many times by different enemies got through many executions but all of those failed miserably.. Second , now he is suicidal tried to kill himself but all those attempts failed too.. Now lets talk about two legends that manage to die... Roger and WB.. Those two has different circumstances when they recieved a death blow , Roger let his head rolled smiling while WB died from hard battle to rescue ace... WB dying moment is understandable cos he fought the World forces bravely while Roger got executed by two unknown weak looking executioner... Why I said weak? Don't you remember how Luffy knock em out in Marineford by his Haki? It seems like Marine only got a normal soldiers doing the execution ceremony .. They are nothing special, so how the hell Roger got his head caught off so easily? It's impossible he doesnt posses strong haki , what's the connection about this being Kaidou a strange?.. Well lets talk about haki , I dont believe Oda will make Kaidou a cursed man thats why he got that super duper tough body.. This is my theory enters , what if Kaidou gain that tough body by mastering his Armanent , actually I wont call him a "master" it's more good to call him out of control.. Why? Okay lets review what Rayleigh said to Luffy about Armament Haki.. This is an ability to make yourself cloak on invisible armor effective in offense and defense , ultimately wearing an armor to yourself could also be removed willingly.. Okay we will go first to offense..Lets give a perfect example , the very good person for this example is Zoro.. Do you guys remember the fight between Tashigi and Monet in Punk Hazard? Although Zoro wasnt fighting or hurting woman seriously ,he still intervene in their fight by throwing a slash to Monet that makes her cheek bled and make her trembled in fear... Then Zoro seriously cut her in half without hesitation although she didnt die.. Why the hell Zoro manage to cut Monet by his long range slash while his blade slipping through the body of Monet couldnt finish her off? We know before they resume their journey; Luffy , Zoro and Sanji train their haki.. Throwing a slash and cutting..This is the instance that Zoro wears an armor to his slash and remove it when she cuts Monet.. A destructive mastery of Armanent Haki , he could make his weapon tough and soft by abiding it to his will.. Now lets go for defensive use of Haki , Lets review the scene when Garp stand in the way of Luffy to rescue Ace in Marineford Arc.. Isnt strange how Luffy manage to beat up his grandpa?, a legend known as Garp the fist got beaten and bled his face to a non-haki Luffy.. We all think that because Luffy is a family , he hesitated and let his grandson punch him...Woah a legend that destroyed so many mountains just to train his haki 28yrs ago to smash the drill of Chinjao got his face smash by mere rookie? How long do you think he train his body to deal his problem to pirates ? Even an Admiral like Kizaru didnt even manage to scratch Marco but when Garp punch him his face received a smashing damage? Wtf Luffy is just like an ant in the storm, here it is the same technique Zoro displayed... Garp let himself as soft as he think that even Luffy that time could manage to beat him.. Even Luffy himself cant believe he manage to pass through Garp , this prove that toughness and softness of your body or weapon could be control when you mastered your armanent ( You could wear an armor and you can remove it if you want).. So this is a good proof why Roger manage to die that time from the hands of executioners..What if Kaidou isnt just some immortal or godly being but actually a man that lost his control on his armanent haki? It's like he cant remove his armor anymore even if he tried to do it..It's not like a curse or something , its like you lose over the control of your own body... As luffy stated in previous anime episode , haki wear out if this occurs his improved ability will get weaker and weaker..In case of Kaidou, he lost control of it by surpassing the limit a human could... Like Katakuri explained , he could see a little bit ahead of future.. He just changed his body molecules to match up the reflexes of Luffy to dodge every attacks of Luffy.. Maybe theres a possibility that kaidou's body toughness due to his supreme Armanent but couldnt control it anymore thats why he cant kill himself too.. What do you think?
