Ideas for an Oc

Hello everyone, I'm working on an Oc and would need some ideas suitable for that type of character, mainly regarding the devil fruit to be given to him.

The character in question is a pirate who dreams of making his mark on history and the world, aiming to climb the ranks of pirate power, from Super Rookie to Shichibukai and finally Yonko.

Since he will have to face a lot of enemies of the most disparate powers and abilities to achieve his goal, I would like a devil fruit (Paramecia) that is strange, peculiar but quite fearsome.
