Jackdaw

Jackdaw is a character featured in the Marvel Comics universe. He was created by Dez Skinn, Steve Parkhouse, Paul Neary and John Stokes, and first appeared in The Incredible Hulk Weekly #57.
A now-deceased hero, the sidekick of Captain Britain, Jackdaw was an Otherworld elf. Jackdaw had been mortally wounded earlier in his adventures, but was revived by Merlyn and given new powers and a new costume.
He was permanently slain later on Earth-238 by The Fury. Jackdaw was literally torn in half by one of the Fury's energy bolts and expired shortly thereafter in Captain Britain's arms. Jackdaw expressed a belief that Merlyn would resurrect him. Saturnyne had abandoned them to escape. Merlyn did not resurrect Jackdaw as it would have damaged his chances of rescuing Captain Britain, who was killed as well by the Fury after Dimples and Jackdaw, and resurrected by Merlyn back on Earth-616.

Jetstream

Jetstream is a Moroccan mutant character appearing in American comic books published by Marvel Comics. Created as a part of the group known as the Hellions, he exists in Marvel's main shared universe, known as the Marvel Universe. His first appearance was in The New Mutants #16.
Haroun ibn Sallah al-Rashid was born in the Rif Mountains in Morocco. As Jetstream, he was a student and operative of the White Queen and member of the original group of Hellions, the trainee group of mutants set up by the Hellfire Club to be a rival to the New Mutants. Haroun felt obligated to be part of the group; they gave him cybernetics to stop his powers from causing self-injury. Jetstream was the antithesis of Cannonball, who could also propel himself through the air and was also the team leader. He engaged in several battles with the New Mutants—mostly petty competition—but occasionally got along with the students, sometimes having dances for socialization.
On the first mission of the Hellions, Jetstream helped to capture Doug Ramsey and Kitty Pryde from the X-Mansion. When the New Mutants came to reclaim their own, Jetstream was defeated by Magma, and quarreled with fellow Hellion Empath. The two teams decided to solve the dispute their own way: a duel between Cannonball and Jetstream with the winner getting to keep the captives. Jetstream lost, but Emma Frost returned in time with Sebastian Shaw to deter the New Mutants from retrieving their friends. Kitty was able to create a diversion for Magik to be able to transport the team to safety. Later, when the New Mutants were in a state of emotional turmoil over being killed and resurrected by the Beyonder, Emma Frost saw it as her opportunity to sweep in and take control. She convinced Magneto—the current leader of the team—to allow the New Mutants to come to the Massachusetts Academy for psychic counseling, where she promptly accepted them into the ranks of her Hellions. The two teams became quite fond of one another, and Jetstream was able to challenge Cannonball to another duel, but the teams were separated when Magneto realized that his emotions had been manipulated by Empath to convince him to relinquish the students.
Jetstream later used his skill with computers to find Empath, who had been captured by the New Mutants. Jetstream later repeated his challenge to Cannonball at a Hellfire Club gala. He also participated in the Hellions' capture of Viper and Silver Samurai, and the Hellions' unsuccessful attempt to capture Bird-Brain. After that, Jetstream joined in the Hellions' mock attack on new recruit Magma during a training session. On the team's final mission, Jetstream went along with the Hellions to retrieve Firestar. They found her in the ranks of the New Warriors and their leaders, Tai and the White Queen, decide to have a series of fights to see who would get her, whichever team defeated more of the other won. This deal was unknown to either team as they were already fighting. Jetstream was defeated by Nova who ended up punching him through a wall. The Hellions, as a team, lost and went home, not knowing that their young lives would soon be over.
Soon after, Emma threw another party which the Hellions as well as the X-Men Gold team attended. Trevor Fitzroy attacks the party, killing Jetstream and the other Hellions to fuel his powers.
Jetstream was resurrected during the Krakoan Age.
Jetstream is a mutant who can generate thermo-chemical energy, accompanied by plasma, and release it through his skin. Jetstream can only release this energy downward beneath him, propelling him through the air rapidly. He can also release energy from all of his limbs, thus traveling close to the speed of sound. Jetstream's body is resistant to his energy, but is not completely immune. To enable him to use his power, the Hellfire Club provided Jetstream with a Frost Industries bionic system. Among these systems was a bionic backpack that could fold away into his body which contained computerized scanning devices and aerial navigation, and rockets in his thighs to help contain, focus, and control his power. Jetstream is a fair hand-to-hand combatant, having been trained at the Massachusetts Academy.
