That one strawhat who neither had balls back when they joined nor grew any within all that time. Strength wise they'd be still below a chapter one luffy or zoro.
Intelligence wise they're shit because they're not strong, thus have low confidence and no brovado at all. They're scum in every aspect you could imagine. No matter how miserable you are right now, you'd never chose to waste your precious time with that piece of useless parasitic piece of shit.
If you know who I am talking about, welcome to the club. Don't argue, it you thought about them you're it, you just haven't realized yet.
