A one piece fanfiction of buggy
A man reincarnated into a young buggy just after Roger's execution. For years he trains in secret, his devil fruit to the pinnacle, his swordsmanship to the top.
When he finally resurfaced he shocks the world with his power and becomes the most terrifying pirate.
With a wave of his hand he turns you to dust, with a slash of his sword he divide the sky.
…
Pretty much his devil fruit becomes so strong he could slit apart atoms and molecules making him able to teleport and kill anyone with ease
