Oh really? Tell me one single time Luffy claimed he will surpass Roger. Because until now he only said he's gonna surpass Yonkos.
The one Luffy wants to surpass > the one Zoro wants to surpass.
Read the manga next time. Thank youu.
nah luffy himself doesnt need to state it
another character did
by your logic surpassing the yonkos and admirals
shanks is no different from say katakuri as one of the benchmarks
better yet he's no different from any yonko or admiral since luffy says he wants to surpass them
following this logic
fuji is also a "benchmark"
his goal to become the pk and finish what roger couldnt
thats his benchmark not someone who never achieved the title.
again get better at this mate. getting a better crew than shanks was whats stated
luffy is well on his way surpassing shanks way before he becomes pirate king.
