Martínez is a well-built black man who is said to be almost two meters tall. In official illustrations he is bald despite being described as having a buzzcut in the novels and has tattoos on both his arms. His usual attire consists of a dark colored tank top and pants, as well as sandals. He occasionally wears a black leather jacket.
Despite his occupation, Martínez is actually rather kindhearted and sincere, noted to despise hurting people and killing them. He has a much more grounded moral compass compared to his other friends in the underground business, refusing to torture young minors with his usual brutal methods or killing children, and has an apparent disgust towards pedophiles. He is supportive of his friends and tends to act as an approachable person to talk to for advice or at least lend an ear to someone, particularly for his close and long term friend Enokida.
Martínez was raised up poor in the Dominican Republic as a boy named Alejandro Rodrigez. He had a huge passion for baseball and strove to make it big by getting into the major league and support his family. While his efforts allowed him to be accepted into the academy, he quickly realized he was no match to the other students there, resulting in him dropping out and turning to the underground to make ends meet.
After a few years of living with this lifestyle, he was presented with the opportunity to join one of the largest drug cartel in Venezuela. He went through the test with other participants, which required them to beat up a traitor without killing him. At his turn, Martínez felt pity for the man and decided to end his misery, shooting him in the head instead. The drug lord, Ramiro Sanchez, questioned him for his disobedience. To appease the man, Martínez lied, claiming he just wanted to test his shooting skill. Ramiro Sanchez took a liking to his answer and allowed him to join. Martínez grew to be a close partner to their leader and well trusted by him, enough to where Sanchez tasked him to become their group's torturer and taught him the necessary skills he needed. Martínez continued to work for him, even ascending so far into the hierarchy to essentially become Sanchez's right hand man until one day he was ordered to kill a man and his entire family, reminding him of his own family back in the Dominican Republic and decided to quit the drug cartel. In coincidental timing, Martínez was tasked the following day to torture a rat in their group, Ricardo Seiya Ortega - an American spy. He was left alone with his target to abstract information from him before killing him, but he instead let the man go. Once Martínez insured the man could escape, he himself fled before the rest of the group found out what he did and headed to Japan.
Upon arriving to Japan, he officially began going by his new name and left his old life behind him. He found work as a torturer for a man named Suetsugu, helping his small gang extract information from people. One of his victims was a man who hid money stolen from him. Martínez promised the man after torturing him he would help him escape with his life if he told him the information he wanted, which the man provides. After reporting to Suetsugu, Martínez had the man take a sleeping pill, knowing Suetsugu would order him to kill the man once they retrieved the stolen money. Once the man fell into a deep sleep, Martínez received the order he was expecting and followed through with it, allowing the man to pass peacefully and unaware.
The following day, Martínez received another job from Suetsugu, who instructed him to get all the information out of a hacker that had been looking into his group recently. Martínez headed to their hideout to find a young teenager strapped to a chair, who proclaimed to have no name, asking for Martínez to give one to him instead. Feeling pity, Martínez injects a truth serum into the boy to get information about him, only for the teenager to use the truth serum to his advantage and make Martínez relax around him, accidentally slipping up and admitting a detail about himself. Now that the boy knew who Martínez was, he proceeded to tell him about Suetsugu and the group Martínez worked for, mentioning their plot to frame Martínez so they could get away from the police. Upon realizing that the information the hacker provided was most likely true, Martínez let the man go and quickly got away before the police could arrive to arrest him.
A few days later, Martínez saw the report of the police managing to arrest Suetsugu and his gang. Without any employer, Martínez began to consider his options for work when he spotted the same hacker, now with dyed blond hair. With the teenager's new look, Martínez decided to give him the name Enokida, which the boy begrudgingly accepted. The two chat and Martínez realized that the boy likely lied to him about the police already being sent to Suetsugu's hideout and that the hacker probably informed the police after his escape, meaning the teenager did not sell him out. With Martínez in his debt, he decided to do what the boy had asked and become his baseball instructor. After asking Enokida if he was free that evening, he took him to see a baseball game with the tickets he got from his past torturer victim. It was assumed after this that Martínez began to resume his work as a torturer with the help of Enokida.
