02Appearance

J.D. Hernández's appearance is unknown. He wears an ordinary black suit with the Speedwagon Foundation 's wheel logo and carries a gun with him for self-defense. It can be presumed that he also wears sunglasses, which is typical of the Foundation's agents.↗↗↗

03Personality

Hernández is a cautious and courageous man who isn't afraid to track down and attempt to capture a serial killer with supernatural powers, despite being an ordinary powerless human and only having a gun for self-defense. He's committed to his occupation, aware that it's the duty of a paranormal investigator to pursue the unknown. However, despite his bravery and commitment to his field, he's naturally afraid and anxious in tense situations, feeling helpless when there's nothing he could do. He wishes that he could confront Fabio in the plaza but his vision blurs and he is unable to even help a single person caught in the attack of El Señor de las Moscas.↗↗↗↗

Hernández is meticulous and inquisitive as he spends five months investigating anything he could find about the serial killing case and then writing a detailed report; he analyzes the commonalities between each case, interprets what kind of person the killer is, and hypothesizes whether the killer's mysterious ability is related to the Ripple. He is also intuitive and has an eye for people, hiring Octavio and Joaquín as informants because he believed they were strong and loved their hometown.↗↗

As the leader of his team, Hernández can be bossy, giving out orders even when he's injured and could fall over at any minute. He cares for his allies and feels responsible for getting the teenagers involved with his mission as they got injured against Fabio. He is very protective of Lisa Lisa, reprimanding whoever insults her like Octavio or Pisco. He is against Lisa Lisa still involving herself with the Foundation when she is in her late nineties, and adamantly opposes her wanting to use the Arrow on herself.↗↗↗↗

04Story

SPOILERS

Background

Around November 1972, the Speedwagon Foundation dispatches investigators to Antigua, Guatemala to examine each crime scene of a serial killer and interview the locals. Hernández is the group's representative and their investigation lasts for 5 months. After, he sends a detailed report back to the Foundation headquarters in Dallas, Texas.↗

The Foundation determines that the killer will strike again during Semana Santa, Antigua's biggest parade of the year in April where the streets will be filled with holy iconography. To aid their investigation, Hernández enlists the help of two local teenagers: Octavio Luna Kan and Joaquín Ruiz-Jorruda.↗

Battling the Monstruo of Antigua

At night on April 20, 1973, Hernández passes by the ruins of the Convento Santa Clara and meets up with Octavio and Joaquín. Octavio informs him that the killer is on the move, and Joaquín grunts and gestures with his arms and body to communicate. Joaquín has a speech impediment and could not speak, but Hernández is still able to understand what he is trying to say through his expressions. Hernández learns that the killer attacked the sacristan at the La Merced church.↗

Aftermath of Semana Santa

The killer's name is revealed as Fabio Ubuh. The Speedwagon Foundation hands Fabio over to the Guatemalan police and informs them how to safely keep him in custody. Since he cannot generate flies from thin air, he is confined to a sterilized room with no ventilation shafts and wears a straitjacket. Hernández visits Fabio several times but Fabio refuses to speak, so they sit in silence each time. However, Fabio finally caves in and explains his past.↗↗↗

A Game of Hopscotch

Accompanied by Lisa Lisa, Octavio, and Joaquín, Hernández drives a car to the location of where a human trafficking gang is rumored to be, according to Octavio and Joaquín's report. The other investigators in Hernández's team follow in separate cars. Hernández feels odd seeing the informants he hired wear the same suits as him. They reach their destination, arriving at a small settlement. However, the place appears to be deserted. They decide to investigate anyways since they came all this way.↗

Peru Arc

Hernández teaches Octavio and Joaquín while they're on the go, educating them on important theories and training them in self-defense and espionage. In 1974, he is with Octavio and Joaquín in Peru, as they look for clues about Alhorn. Octavio complains about having to study, but Hernández emphasizes the importance of desk work and urges Octavio to emulate Joaquín's dedication. Octavio is more interested in learning the Ripple power that Lisa Lisa uses.↗↗

The Search for Alhorn

In the late 1970s, Hernández and Sasha encounter Alhorn a second time by following him to a casino in São Paulo. However, they fail to capture him. One of his companions uses their Stand to cause many casualties while Alhorn flees the scene. Alhorn also manages to escape from their third encounter, which follows a similar pattern. Aside from Alhorn, Sasha and Hernández search extensively for Octavio and Joaquín's whereabouts, but they remain untraceable as well.↗↗

Researching at Lake Titicaca

In 1986, Joseph Joestar tells Hernández to ensure Lisa Lisa stays home and not involve herself with the Foundation anymore as she is in her late nineties. Hernández brings a medical staff along with him and follows Lisa Lisa to the Andes, taking a separate train from her. They meet with her in the station, not wanting her to travel alone.↗↗

Invading the Amazon

Hernández travels with Sasha, Lisa Lisa, and the Rueda Squad to the Amazon rainforest where the Selva Cartel is operating. After about an hour, the cartel's guards confront them, asking if they're lost tourists and mocking them. Lisa Lisa attempts to defuse the situation and requests to meet with their boss, claiming that they're acquainted with him. Nonetheless, the guards have direct orders not to communicate with any intruder and to eliminate them instead.↗

It is unknown whether Sasha and Hernández successfully rescued Octavio and Joaquín, as their fates in the Speedwagon Foundation records are officially unrecorded. However, they acquire Octavio's Arrow and securely place it in a storage area known only to a few.↗↗
