Don't think Magellan can stand this, some of Kumas attacks are enormous, & i do think he can push poison if he can push abstracts like pain. I'm thinking his steel body would only be vulnerable to Kinjite, he's faster than Magellan with the teleporting & Luffy's Jet Bazooka made me see Magellan takes normal damage from impacts. Kumas air cannon would do devastating damage, his laser has destructive power enough to melt metal and if he gets off an Ursus Shock it's done.
sorry,but I really consider magellan as strong as an admiral,what he did in impel down was impressive: he defeated one after the other rufy,teach &his crew (who would have died without shiriew's antidote),ivankov and inazuma,and so many other pirates,although weaker than the mentioned ones. his defeat was not a shame,as it was the most dangerous guys who beat him: in the level 6 (where not even a revolutionary such as ivankov stayed) there were dudes who said that they had been defeated by WB,whom not even ace was allowed to fight directly,as WB's subordinates protected him against such a "weak" enemy.
kuma is done for
Meh, all of you are taking the original Kuma shown in Thriller Bark and no the one trated by Vegapunk full-cyborg that appear in Marineford. With that, it's like putting Nightmare Luffy in all the fights that Luffy will fight.
No one follow the rules
I don't care even if kuma can use kizaru's beams. imo,magellan did what akainu would have done at the war: defeating all his opponents one after the other.
