Trebol

Trébol is a member of the Donquixote Pirates.

Appearance
Trébol is a very bedraggled individual. He has dark hair that is worn as a bowl-cut. He wears a small pair of sunglasses and has a broad flat nose, which is commonly seen with some snot hanging out. He has a long, thick beard and some stubby hair on his upper lips. He holds a scepter with a club suit design on the top.

His lips are a bit thicker than normal and his teeth are round and have some space between them. He has a prominent hunch and appears to be considerably taller than normal people, although a slouching back takes some height away. His attire consists of a long coat with a ring-pattern on it. He usually looks as if his body is made from a thick substance that is secreting off his body. His body type, posture, and attire make him look like a giant snail.

Personality
Trébol seems to have a problem with how close he gets to someone with whom he is talking, making people comment that he is too close.

He is also somewhat bold and insensitive, as he casually asked Baby 5 if Doflamingo killed another of her fiancés, as well as asking Baby 5 to marry him as a joke, knowing that it would make Baby 5 feel compelled to help him out.

Like most One Piece characters, Trébol has a distinct laugh: "Behehehehe".

Donquixote Doflamingo
Trébol is very casual around Doflamingo and doesn't seem to be scared of him, as he get awkwardly close to him, much to his annoyance. Trébol often refers to him by his nickname "Doffy".

Baby 5
Trébol is somewhat rude towards Baby 5, as he casually asked her if Doflamingo killed another of her boyfriends, as well as making fun of her inability to say no to people.

Abilities and Powers
Unknown Ability Trébol was shown to have the ability to transform into a sticky liquid of some sort, which allows him to stick to walls. Whether this ability stems from a Devil Fruit or not is unknown.

Dressrosa Arc
Trébol is first seen when Baby 5 is looking for him, sticking onto the wall of a house, remarking that the country is in chaos and suggesting that the rest of the world is in chaos too. He then rushes up to Baby 5, getting way too close to her, and asks her if it's true that Doflamingo killed another of her boyfriends, only to be told to back off. Trébol starts flirting with Baby 5 for a bit, to which Baby 5 tells him that he's gross and that Doflamingo wants to see him and that Trébol brings it with him. He then suggests that Baby 5 should marry him instead of some random man who'll only get killed by Doflamingo but quickly laughs it off, as a joke.

Later, in Doflamingo's meeting room, Trébol drops himself off the ceiling and hands Doflamingo the object he desired, getting too close to him again. The object is then revealed to be the Mera Mera no Mi.

Trivia

 * "Trébol" is the Spanish word for clover. This matches the card suit motif of Doflamingo's subordinates, as the clubs suit is called "tréboles" (clovers) in Spanish.
