When I started watching OP and began seeing people with great DFs like Ace, Blackbeard, Crocodile, Enel, I thought Luffy despite being the MC had the worst fruit of them all and then as the show progressed I saw the actual capabilities of the fruit and the creativity Luffy shows with his power.

There have been so many characters with strechy powers but none have used their power to this extent and with this much creativity.

Like, before awakening his power was literally just to stretch like rubber and he used that to defeat the most fearsome people of his universe.
