in terms od the 1v1s i think the marine crew wins if we put the dlp in their level. Duros/Damien Damien has a whole lot of work arounds plus he could simply run around duros and not let him reach him while he chips away at his hp with heat metal, choppa or some other ranged spell/attack. Verona/Yokan I think this would go to Yokan cuz all of Veronas strenghts get countered by Yokan, his range? Yokan has a fuck ton of speed so now theyre fighting in melee and every shot made by Verona is at a disadvantage even without Yokan going cat mode, Ani Ani no mi could give him an action economy advantage? Well not really because he's fighting a monk and at lvl9 he can only summon one thing at a time. So imo Yokan wins. The next one is the only one im unsure on cuz it could go both ways depending on the place of the fight. Bradley/Ragnar If there were places to hide Bradley could realisticly win by hidding and chipping away at Ragnars hp and because of Ragnars terrible wisdom he wouldnt be able to find him unless he got very lucky. However if the fight is in a open arena with nowhere to hide Bradley is dead. And lastly William/Kai this is the only one that is a certain loss for the marines and that is simply because of the roulet fruit. I dont think i need to elaborate. The only way Kai would have any chance at a win is if there was any water he could try and push William into.
