History
Allen would be born from a marriage between a pirate and a marine in the island of Logue town. His father was a marine that was a marine user of the black leg style, and his mother was an ex-pirate which always told Allen of her adventures in the grand line and how it felt to live free on the seas. When Allen was born his parents already had a child 2 years older than him, he was a half mink born of an affair between Allen's father and a female mink. His brother's name was Netanel, each one of the brothers had their dream, Netanel wanted to be a marine like his father and Allen wanted to be a pirate like his mother, they both were trained in the black leg style since childhood by their father, which always wanted both to be marines, but Allen and his mother never liked this idea. After his mother's death by a disease, he couldn't stand being raised by only his father which surely would force him to be a marine against his will. So he ran away from home and lived as a thug in the streets of Logue town beating up people for money.

A little time after that he tried to rob a muay Thai teacher that threw him in the ground with ease and defeated him, the teacher started to feed, raise and train Allen in his own home since he had seen the boy was good in combat and had a great sense of justice even if it wasn't very clear. At 19 his master told him after some time that a long time ago he was also a pirate, teached him about navigation and pirates, and that he would grant Allen a devil fruit that he found in the Grand line if he was worthy of it. His master made a tournament between his strongest students and among them was Allen, who after a long time of fighting had reached the finals and won the tournament. He won the fruit but kept it to eat when he reached the age of 20 years, a day after that a gang of armed thugs broke into their house at night and were torturing his master looking for the boy who had possession of the oni-oni no mi.

Allen woke up to his master's screams and was shocked when he saw the scene. The thugs then began to run after Allen, but Allen ran to his room and ate the fruit, turning into a big and red horned monster, as soon as the gang saw the boy in that state they killed his master with a single shot on the head. That made Allen get lost in his rage and didn't remember anything that happened after that night, he just woke up to corpses in his house including his master. He was sad and realized how heavy is to carry devil fruit but to honor the master he promised being a pirate and search for his dreams.

Trivia

 * Allen hates marines but still has the potential to become one.


 * Allen doesn't use his full zoan form all the time, he prefers the hybrid because it is less monstrous.
