Diesel

Towering yet spindly through the legs, Diesel pairs a thin frame with a tiny mustache. The eye is drawn first to the chimney-shaped hat perched on his head, which puffs out smoke, and to the pair of wheels mounted on either flank that he spins by hand when dashing, though they serve no real mechanical purpose. His tribal heritage shows in the extreme reach of his arms, each fitted with a second elbow joint.

For most of his appearances he favors a dark suit topped with an oversized pink bowtie, dark trousers, and a mask shading his eyes. That look changed once the Fire Tank Pirates dragged him to their hideout, where he was washed up and made to swap into a lighter outfit.

Devotion to Big Mom defines him. He slaughtered an entire workforce to bring her a batch of rare flour, and the moment Brulee was beaten he bolted off to deliver the bad news to his captain. His self-image rests on his foot speed, a subject he loves to boast about. In keeping with the cast's running gag of distinctive laughs, his own mimics a chugging locomotive, coming out as Shuppoppoppo.

Speed is Diesel's calling card. He insists he is an exceptionally quick runner, and the claim holds up, as he can break into a furious sprint. His strength matches it: he once hauled six passengers at once, among them a Heavy Point Chopper and the bulky fish-man Jinbe, all while moving at pace. He is no slouch in a fight either, having cut down a factory full of armed laborers with ease.
