AppearanceHawkins is a tall man, with triangle symbols on his brows and red eyes, wearing an extraordinary suit and having flowing golden hair that reaches down to the top of his abdomen; he also has a medieval-style cross tattoo ed at the base of his throat at the front of his neck. His attire includes a pure white coat with a ruffled neckline and sleeves; he also wears purple trousers and a dark sash. It can be seen that this large sash is made from fur, and has a red scarf or sash tied around the center of it. He also has what appears to be a piece of jewelry hanging from this sash. Hawkins also wears dark gloves similar to those worn by Blueno of CP9, and an armor-like armlet could be seen on his left arm around his left bicep, which also extends to cover his left shoulder. On his hip he carries a sword with an elaborate pommel that resembles a voodoo doll, which he ties to his waist with the pink scarf around it.
PersonalityHawkins portrays himself in a noble and enigmatic manner. In particular, he has a notion about foretelling the fate of everything that he sees. He notes the potential of death and fate in things from a person's clothing to other pirates. He also remains completely calm regardless of the situation, showing no emotional response after Roronoa Zoro nearly attacked a Tenryuubito or after learning the news of Portgas D. Ace's upcoming execution, events which drove many other members of his crew and other Captains to panic. He also appears to be against the idea of needless violence, as seen when he stopped his crewmate from attacking a waiter after the latter accidentally spilled spaghetti all over his clothes, even then apologizing to the waiter himself.
When approached by Kizaru, he calmly used his tarot cards to calculate all the probabilities of the battle, and upon foretelling that he wouldn't die, remained calm even when subsequently attacked. He has been known to express outward shock, as seen when Urouge utilizes a strength and size enhancing technique against a Pacifista.
RelationshipsHawkin's crew appears to be quite loyal to him and will, without fail, follow his every imperative to the last word. In the anime, they were even willing to attempt to hold down Kizaru at bay to buy their captain some time to escape when the admiral suddenly appeared, confronting Hawkins' entourage.
As for his fellow Supernovas, the interactions that Hawkins had with those whom he encountered were neither confrontational, nor associative. He does however inform Urouge that he did not see the shadow of death upon him yet when Urouge asked whether having both a Shichibukai and an Admiral as opponents would be the end for him, which Urouge treated as a friendly joke from a rival.
Abilities and Powers“ Concerning the fate of your clothes... I'm sorry to inform you, but its a very cruel and unlucky day.
Hawkins often speaks like a fortune teller and has been noted to mention reading "signs". He can work out to a percentage the chances of something happening. However, how is he able to do this has yet to be fully explained. He also can use various tarot reading cards that can assist him with determining the outcome of any occurrence.
Devil FruitBasil Hawkins' as-of-yet unnamed Devil Fruit ability enables him to form voodoo dolls of straw that redirect the flow of attacks to another person. Whether Hawkins can directly choose who receives the damage is unknown. The Devil Fruit also enables him to transform into a giant scarecrow-like entity. He also resembles a voodoo doll seemingly made from straw, with metal nails functioning as claws/fingernails. After bodily damage is taken, voodoo dolls that represent the people who took the damage are shed from his body, showing the effects of the attack. However, it would appear that he has a finite amount of voodoo dolls on his person at a time. This is noted when he told Kizaru that it was unwise for him to fight with a mere ten "men" (voodoo dolls). This implies that he can hold a much greater amount of dolls on his body. The voodoo doll ability is apparently very powerful as Basil was kicked in the face, slammed into a building and shot with a laser (all at the speed of light) and emerged without a visible scratch on his body. Unfortunately, if Hawkins is injured continuously, the supply of the voodoo dolls held within his body will ultimately exhaust. At that point, he then becomes as vulnerable as anybody else. This is seen when Kizaru finally manages to fell him after a series of attacks that caused several of the voodoo dolls to fall from his body all at once. It also seems that the dolls' ability to transfer damage is limited only to bodily injury. This is because the dolls weren't able to re-direct Hawkins' blindness when Kizaru blinded him with intense light.
AttacksGouma no Sou (降魔の相) Devil Conquering Phase): Hawkins transforms into a giant scarecrow-like entity. He also resembles a voodoo doll seemingly made from straw, with metal nails functioning as claws/fingernails. However, his Devil Fruit is not a Logia (as noted by Kizaru). So, he can still be hit by attacks, as seen when he is kicked by Kizaru. This was first seen used in the battle against Admiral Kizaru. In the FUNimation subs, this is called Demon Face
Sabaody Archipelago ArcHawkins was first seen in a restaurant along with other Supernovas Capone Bege and Jewelry Bonney with their crews. A waiter accidentally spilled food on one of his nakama. His crewmate complained only to be told by Hawkins it was a very unlucky day for him. Upon hearing of Luffy's attack of a Tenryuubito, he was the only one whose position as to leaving or staying was unclear - all he said was that "the signs do not show" his crew would "fall today".
Kizaru comes across Basil Hawkins sitting down, surrounded by his entourage of crewmen while he simply states that he will not die today. After sitting down and working out his chances against the admiral, Kizaru attempts to take out Hawkins, only to find that his attacks have no effect and Hawkins remains unhurt. He then sheds two voodoo dolls from his arm, stating that ten men wouldn't suffice against Kizaru. The battle is joined by Urouge and X. Drake, as well as one of the Pacifista on the archipelago. 
After Kizaru sends Urouge flying, Hawkins transforms into a giant straw monster in liking of a large voodoo doll baring Hawkins' semblance in order to defeat him.  However he is blinded by Kizaru who then deducts that Hawkins' ability is not a Logia-type. Hawkins is nearly killed, had it not been for the intervention of Scratchmen Apoo.  However, Kizaru reforms himself, dispatches Scratchmen Apoo easily, then turns his attention to the two remaining Supernovas. After defeating X. Drake, Kizaru defeats Hawkins by firing a light-based arrow into his abdomen. Hawkins is about to be finished off by Kizaru when he is suddenly interrupted by his Den Den Mushi, saving Hawkins from death.
