Raymond Warren is the uncle of Gwen Stacy and the super villain known as the Jackal. After being accused of doing illegal genetic experiments, he was fired from Empire State. Despite never being formally charged, Raymond had a real downfall in his career.
At some point, Raymond became Jackal. He ran into Spider-Man during a heist where he got away upon getting Gwen Stacy out of the moving traffic. Later on, he crashed Spider-Man trying to intervene on breaking up the fight between Herman Schultz and Clayton Cole where he stole their equipment and used them for himself. Spider-Man had a hard time fighting Jackal until Herman and Clayton helped him out by telling him how to overcome each one's technology. Spider-Man does that and removes the technology from Jackal who gets away. Later that night, Jackal regresses back to Raymond as he meets up with Gwen.
Raymond later visited Horizon High in an attempt to get a teaching job there and met Peter Parker. While talking to Max Modell about the teaching position, Raymond was turned down due to the bad press he previously received. During his visit to Horizon High, he injected a substance in young Aleksei Sytsevich.
Arriving at Osborn Academy, Raymond speaks to Norman Osborn for his audition for a teaching job only for Norman to turn him away as well. Raymond chaperoned the dance where he witnessed Aleksei Sytsevich becoming Rhino. Raymond slipped off. Upon arriving at Raymond Warren's house, Spider-Man was ambushed by Jackal. Upon discovering the truth, Gwen Stacy used an antidote to regress Jackal back to Raymond. She stayed behind to await the police while Spider-Man heads off to cure Aleksei. Raymond made the news where he had been arrested for secretly experiment on Aleksei Sytsevich. Norman Osborn saw the news and commented that Raymond would've made a good teacher.
Later on, someone stole Raymond's identity while he was still in prison and used it to manipulate Spencer Smythe as they both have a mutual enemy in Norman Osborn and Max Modell. During the secret heist on Oscorp, Spencer Smythe made off with the confiscated spider experiments that Raymond worked on and bumped into Miles Morales causing the Electrolis Arachnatis specimen to get out and bite Miles. "Raymond" was not pleased with the escape of the Electrolis Arachnatis specimen. After Spencer Smythe was arrested and was being escorted to his cell, he noticed Raymond in his cell. When Spencer asks how he got recaptured, Raymond stated that he never escaped from prison.
During his time inside a cellular regeneration tank, Miles Warren had his body genetically altered, giving him an appearance of a humanoid jackal.
Superhuman Strength: Jackal possesses superhuman strength. His great physical strength also extends to the muscles of his legs.
Superhuman Speed: Jackal is capable of running and moving at speeds that are beyond the natural physical limits of the finest human athlete. Jackal is able to run at speeds sufficient to allow him to keep up with the likes of Spider-Man.
Superhuman Stamina: Jackal's advanced musculature produces less fatigue toxins during physical activity than the musculature of a normal human. At his peak, he can physically exert himself for several hours before the build up of fatigue toxins in his blood begins to impair him.
Superhuman Durability: Jackal's body is harder and more resistant to certain kinds of injury than the body of an ordinary human. While he isn't bulletproof, he can withstand great impact forces, such as falling from several stories or being repeatedly struck with superhuman force, that would severely injure or kill a normal human with little to no discomfort.
Superhuman Agility: Jackal's agility, balance, and bodily coordination are similar to those of the cat he takes his name from and are beyond the natural physical limits of the finest human athlete.
Superhuman Reflexes: Jackal's reflexes are similarly enhanced and are superior to those of the finest human athlete.
Superhumanly Acute Senses: Jackal's senses of sight, smell, and hearing are heighten to superhuman levels. Jackal's is able to see objects with perfect clarity at much greater distances than a normal human. He retains this same level of clarity at night, even in near-total darkness. He may also be able to see into the infra-red edge of the electromagnetic spectrum, allowing him to detect a person's body heat in the absence of any light. His sense of hearing is similarly enhanced, enabling him to detect sounds ordinary humans can't and sounds that they can, but only at far greater distances. Jackal's is able to detect the slow, steady rhythm of a normal human heartbeat within a short distance. His sense of smell is particularly acute, enabling him to track an individual by scent over great distances, even if the scent has been eroded over time by certain natural factors.
Regenerative Healing Factor: If Jackal's does sustain injury, he is rapidly regenerate damaged bodily tissue much faster and more extensively than a normal human is capable of. Injuries such as multiple slashes, severe burns, or damaged caused by powerful electric shocks can completely heal within a matter of hours. However, Jackal's healing powers aren't sufficient to regenerate a missing limb or organ.
Claws and Fangs: Jackal's nails are actual short, hardened retractable claws. These claws are razor sharp and are capable of easily rending flesh and bone. Coupled with his great strength, Jackal's claws are capable of rending most conventional materials, including some types of metals He also possesses razor sharp fangs that, while they serve little practical use, can be used as highly effective weapons in very close quarters combat.
Genius Intelligence: Miles Warren was a genius in the fields of biochemistry, genetics, and cloning. Skilled martial artist and gymnast.
