Hackett is a former pilot of the Royal Air Force who later became a henchman of the heroin manufacturer China White.[1]

China conducted her business from an island volcano in Fiji, and communicated her orders to Hackett from there. Decade ago, Hackett insinuated his way into the lifestyle of millionaire playboy Oliver Queen. He convinced him to invest in several illegal offshore accounts, though Queen was unaware that the money was being used for drug trafficking.

Hackett arranged to meet China White, but Oliver insisted on coming along and they both embarked upon the "Pacific Ocean" ship. Queen's presence threatened to expose China White's operations, and she ordered Hackett to kill him. As he considered himself Oliver's friend, Hackett couldn't bring himself to murder him in cold blood, so he tossed him over the side of the ship instead.

Ollie survived however and encountered Hackett again in Fiji where he learned that he was actually working for China White. The two fought one another, but Ollie managed to get away. When Hackett reported back to China White, she was furious at him for not shooting him in the head as originally instructed.[2]

John Wilson, also known as John Henry, is a fictional DC Comics superhero.

After the conflict, Wilson discharged and took work in a local machine shop and settled down in Knoxville, Tennessee with his wife Lucille and baby daughter Loretta. On the night of March 17, 1955, John and his family were attacked by the local Ku Klux Klan. He was lynched and his family was burned to death. After the Klan left, John survived his lynching. Devastated by the death of his family and the police blaming him for the murders, John followed the Klan members. John then forged two 20 lb. iron sledgehammers, donned an executioner's hood, and became the vigilante known as John Henry. For three months, John plagued the Klan and had killed two Klansmen in his crusade. John Henry's reputation attracted the news media and remained a hot staple on the public, including the Martian J'onn J'onzz, who considered him an actual American hero. Tragically, John was wounded by the Klan and stumbled into a backyard. He was discovered by a young white girl, who outed him out despite John's pleading for help. Once caught, he was burned alive.[14]

However, his death didn't go unmentioned and his endeavors was highlighted in the television news show The Big Picture which its host extolled Wilson's stance against racism and criticized the American government for ignoring the serious issue. J'onn J'onzz saw this and was very dismayed of Wilson's death which contributed his demoralizing faith for humanity.[15]

Following the defeat of The Centre, a young John Henry Irons sat reading near John Wilson's gravestone.[16]

He had heard about the vigilante John Henry who wielded two sledgehammers in his war on the Ku Klux Klan before they ultimately killed him. Upon receiving one of these sledgehammers from an unnamed old man, John Henry Irons became John Henry Jr. While the old man says that he would have more power when he wielded both sledgehammers, John Henry Jr. never found the other sledgehammer. He later went missing after he helped bring the last of John Henry's murderers to justice.[6]The final issue of Flashpoint Beyond revealed that John Henry Jr. was among the thirteen missing Golden Age superheroes in the Time Masters' capsules. When those capsules failed, the thirteen were all pulled back to their own respective time periods with history rebuilding around them.[17]

John Henry Jr. was among the Lost Children on Orphan Island. He mentioned to Stargirl that he was looking for the second of John Henry's sledgehammers when he ended up on this island.[18] After Corky Baxter of the Time Masters mentioned that the Lost Children will be remembered by their families when they are returned to their own time, John Henry Jr. claims that it would be like they never left. During the raid on Childminder's castle, the Lost Children fight the Child Collectors as John Henry Jr. and Cherry Bomb are comfortable against the odds.[19] John Henry Jr. is among the Lost Children that are "nested" by the Child Collectors.[20] Thanks to a diversion from Corky Baxter, Boom used this diversion to fre everyone. Following Time Master and Childminder's defeat and Wing being sent back to his own time, John Henry Jr. is among the Lost Children that are brought to Stargirl's time by the Hourman android due to paradoxical reasons.[21]

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.[29] The second Hyena debuted in The Fury of Firestorm #10 (March 1983) and was created by Gerry Conway and Pat Broderick.

Both werehyenas had problems with authority and resented Firestorm for interfering in their vendettas. The unique feature of the Hyenas was that they turned into werehyena forms whenever they were under great emotional stress, not only when there was a full moon. This meant that they could attack foes in broad daylight and that they would revert into their human forms when their emotional tension was relieved.

The first Hyena, Summer Day, joined the Peace Corps as a result of relational issues with her father and was turned into a werehyena as a result of 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.[30]

The second Hyena, Doctor 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 into the Hyena and infected Jivan with the werehyena curse. Professor Stein noted that being the Hyena seemed to have warped Jivan Shi's mind.[31] 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[32] and the other appeared as a member of the Injustice League in One Year Later before being shot and killed by Parademons that were attacking the villains' camp.[33]

A pack of at least five new werehyenas, presumably suffering from the same curse as Summer and Jivan, were seen in San Francisco some time after the death of their remaining predecessor. They were promptly defeated and permanently returned to human form thanks to Zatanna, the Vixen and the Black Canary.[34]

In 2011, The New 52 rebooted the DC universe. The Hyenas are reintroduced as mercenaries who received special drugs that gave them super-strength and super-velocity, with the side effect of a constant laugh.[35]

During the Forever Evil storyline as part of The New 52, the Summer Day version of the Hyena appears as a member of the Secret Society of Super Villains. The Crime Syndicate sent the Hyena with Black Bison, Multiplex, Plastique and Typhoon to finish Gorilla Grodd's job. The villains were defeated by the Rogues, since one of the targets was the hospital that was treating Captain Cold's sister.[36]
