Professor Hughes was a professor at Midwestern University. Jay Garrick worked under him when an experiment with hard water vapors gave Jay Garrick his super-speed.

Professor Hughes was still working at Midwestern University at the time when Mister Alpha was causing havoc. He helped the Justice Society of America defeat him.

In the pages of "The New Golden Age", the Prime Earth history of Professor Hughes became obsessed with unlocking mankind's potential after seeing the news about Green Lantern. After his tests on animals, he secretly used Jay Garrick as a guinea pig for an experiment involving hard water vapors. This led to Jay Garrick becoming Flash. Since then, Professor Hughes tried to replicate the experiment and failed until he was approached by Parsifal of the Nazis who blackmailed him into working for the Nazis as he has evidence that he killed the doctor that tended to Jay Garrick. He made weapons for the Nazis, created an element-manipulating armor where he took up the alias of Doctor Elemental, and turned a bear into his cyborg henchman Ro-Bear. In 1941, the Justice Society of America broke into Doctor Elemental's lab that had connections with the Injustice Society where they fought his robots and Ro-Bear. Doctor Elemental proved to be a match for the Justice Society. When Boom time-traveled to the 1940s and helped her father Flash, Doctor Elemental was defeated where he got away. His hard water vapor worked on a younger Judy Garrick in 1949 which led to her becoming Boom. In 1963, Boom assisted Flash in rescuing Joan Garrick from Doctor Elemental. Though Boom rescued her mom and got a look at Doctor Elemental's face, she suddenly vanished. Only Doctor Elemental remembered her when he got away. Back his true identity, Professor Hughes approached Garrison Slate where they founded S.T.A.R. Labs. After Boom was among the Lost Children rescued from Orphan Island, Doctor Elemental found out and started targeting her. The Terrificvision made by Mister Terrific and Quiz Kid helped to get into Joan's memories and help Flash recognize that Professor Hughes is the true identity of Doctor Elemental. As Flash and Boom hide out with Doctor Mid-Nite in Brazil, Doctor Elemental sent Ro-Bear and some of his robots to keep Flash and Doctor Mid-Nite busy while he led some other robots to capture Boom. After interrogating Ro-Bear, Flash found Boom in Doctor Elemental's hideout on an island in the Atlantic Ocean where he planned to use Judy to power his machine that would cause a global transformation in the human race. Flash rescued Boom and thwarted Doctor Elemental's plot as Doctor Elemental got away. While in an underground cavern, Doctor Elemental was approached by a mysterious person.

Hyena

Further reading Hyena at the Comic Book DB (archived from the original)

The Hyena is the name of two fictional supervillains published by DC Comics. The first Hyena debuted in Firestorm #4 (September 1978) and was created by Gerry Conway and Al Milgrom. The second Hyena debuted in The Fury of Firestorm #10 (March 1983) and was created by Conway and Pat Broderick. Both are werehyenas who transform when under great emotional stress.

The first Hyena, Summer Day, joined the Peace Corps as a result of relational issues with her father and was turned into a werehyena after an accident in Africa. Taking the name the Hyena, Summer returned to America and began attacking both criminals and police officers. A result of her condition is a steadily progressing madness.

The second Hyena, Jivan Shi, was a psychiatrist whom Summer Day had fallen in love with while he was attempting to treat her werehyena condition. One night, as Summer and Jivan were embracing, Summer transformed and infected him with the werehyena curse. According to The Fury of Firestorm #10–13, the madness suffered by the werehyenas is one's bestial side taking over, coupled with an exaggeration of negative emotions.

In Infinite Crisis, Deadshot killed one of the Hyenas after a prison breakout and the other appeared as a member of the Injustice League in One Year Later before being killed by Parademons.

A pack of at least five new werehyenas, presumably suffering from the same curse as Summer and Jivan, were seen in San Francisco before being defeated and cured.

In Forever Evil, the Summer Day incarnation of Hyena appears as a member of the Secret Society of Super Villains.
