Baku/Personality and Relationships

Personality
As one of the other entities that is created from the Heka fruit, the personality is stretch out of the user. So it would appear that Baku is the physical manifestation of Haku's own depression and other sadden emotions. So as such, Baku is extremely calm and doesn't seem to be scared of things that he would go up against.

But he speaks in a slow and depressing manner, he seems to have a respect for others. As he doesn't give out insults or anything like that, compared to his other brothers. Baku takes a calm and collected view to life, whenever he is summoned he often will be happy that he was. But he still seems to be cruel and destructive, seem loving to fight as well. Which has made Baku both scary from his appearance and personality.

Family
Among his family he seems to be very loyal to his mother or at least what he believes to be his mother. Hecate, he has claimed that he is the child of Hecate because of the devil fruit that held a power similar to hers. So as such Baku is extremely loyal to his family, but he is the big brother so he is in charge.

Haku and Taku
Among his brothers since they are really two other whole entities that he had created, he has full command over them. So he is the big brother among the two, he uses his brothers as weapons and they fight alongside of him. But often he does yell at them to do stuff because they do share just one brain so as such. Haku needs to often give orders to Taku and Baku to do something, often trying to capture someone. But other than this Haku seems to get along greatly with his brothers and can become a triple threat to the world.
