add to that his crazy lineage - son of dragon, grandson of garp the fist, brother to fire fist ace son of pirate king, brother to revolutionary sabo (who did some crazy shit as well). only man to invade all three govt facilities. only man to invade wci and return back since gol d roger. defeated two yonkos in a single battle. has 3 road ponegliffs. has power over crucial territories like fishman island and wano.
if blackbeard doesn't do something drastic like killing shanks or getting a ancient weapon for himself , luffy will definitely be the most wanted pirate alive.
