Rak Roberts

Roberts (ロベルツ Roberutsu) is a rookie pirate who hails from the West Blue, being Captain of the Dread Pirates. He started his career of piracy at 20 and didn't enter the Grand Line until he was 25, choosing to gain a stronger crew and improve his own skills in the mean time. Unlike most pirates who began after the execution of Gold Rogers, Roberts has no interest in obtaining the legendary treasure One Piece or becoming Pirate King. Instead, he has become a pirate to search for adventure and romance. His epithet, Dread Pirate comes from his policy to keep no prisoners, killing them instead.

Appearance
Due to his Devil Fruit, Roberts takes on the appearance of a human-goblin hybrid with: scaly green skin, sharp golden eyes, and shoulder length black hair. His mandibular canines are quite long, extending over his upper jaw, and often above his lip, while his nails are long and sharp as well. The clothes he wears are very simple: a white long sleeved shirt beneath a brown leather vest that is tied shut along the front, and plain brown pants. This appearance is what is known to the world, as he has used his hybrid form as his main appearance since he ate the fruit.

His full goblin transformation is much larger than his hybrid form, gaining significant muscle mass. He loses all hair while fully transformed, gains four small horns on his head, and his ears become elven and larger than before. He rarely makes use of this power, as he becomes too strong for him to have fun against most opponents. He will only enter this form when his hybrid form isn't powerful enough to beat the opponent he is facing. Because of this, very few people know what his full goblin form looks like.

Roberts' human form is used almost as rarely as his full goblin form is. After fully transforming, he needs to recover as a human for an amount of time; and if falls into the sea, he will be forced into his human body. Other than that, he will occasionally become human so as to move around incognito. As a human, Roberts looks much the same as he does in his hybrid form, only without the goblin traits. His eyes become less sharp, his teeth less pronounced, his nails shorten, and his hair even gets longer. He tends to wear his hair in a ponytail, and different clothing so he looks less like his bounty poster.

Estocs
Roberts carries two identical estoc swords, one hanging on each hip. These swords are are long, without any blade on them. Instead, they have an incredibly sharp point at their end. The base is fairly thick though, which makes them quite sturdy.
