Blackjack O'Hare

Blackjack O'Hare is a fictional anthropomorphic hare in Marvel Comics. The character, created by Bill Mantlo and Sal Buscema, first appeared in The Incredible Hulk #271.
Blackjack O'Hare is a mercenary and leader of the Black Bunny Brigade. He was hired by Judson Jakes and Lord Dyvyne to kidnap Lylla, the C.E.O. of Mayhem Mekaniks. He planned on betraying his employers by marrying Lylla and inheriting the company, but was found out. He was rescued by Rocket Raccoon and after a series of incidents that caused him to question his own loyalty, he aided Rocket in defeating the tyrants and left with his new friends to start a new life.
All this appeared to be false when Rocket visited Halfworld and discovered that Blackjack, along with Lylla and Wal Rus, were all actually service animals for the mental patients who inhabited the planet. Blackjack married Lylla after Rocket left to ensure the imprisonment of a dangerous criminal.
However, this story was immediately retconned as Blackjack returned as a mercenary and adversary to Rocket and Groot. Blackjack was once again working for Dyvyne with his next assignment being that he kidnap Princess Lynx. Rocket, Groot and Wal Rus arrived to defeat Blackjack, his brigade and Dyvyne, once again.
He turned up again, disguised as an impostor Rocket and framing him for a series of murders. He reveals his identity to Rocket and claims that the reason for framing him was that he ruined his chance to assassinate Princess Amalya and destroyed his reputation in the process. Amalya had become a "General" and arrived with Rocket's ex's in an effort to exterminate him themselves. Blackjack considered the possibility of assassinating her now, but was shot by Amalya because he was talking out loud. As a last ditch effort he fires a missile at Rocket, but it gets deflected and Blackjack is presumably killed.

One Above All

One-Above-All

The One-Above-All was created by Mark Waid and Mike Wieringo and first appeared in Fantastic Four #511. In his few appearances, he took the appearance of Jack Kirby.
The One-Above-All is the sole creator of all existence in the Marvel Multiverse and possibly the Omniverse. He is also the supervisor of the Living Tribunal.
When a pregnant Susan Storm feared for her husband's possible death at the hands of the "all-powerful", the Silver Surfer and Uatu the Watcher tell her that there is only one true all-powerful being and his only weapon is Love. When Doctor Strange encountered Eternity, the abstract entity stated that only God is the ruler of all realities. When Thor compared his power with Odin and other gods and abstract entities, he notes that the Creator of All Universes must be far more powerful than all of his creations combined.
The Living Tribunal was stated to be the representative of the One whose might far exceeds that of Eternity. Master Order and Lord Chaos wished that the Supreme Will may smile upon Adam Warlock, who also described the Living Tribunal as the servant of the being above even the gods. When the Cosmic Cube Kubik met the Living Tribunal, the being also stated the same thing about himself and again when he undoes the destruction caused by Adam Warlock with the Infinity Stones. When Protege tried to become the most powerful being in the existence, he was instead absorbed by the Living Tribunal, who stated that it was impossible to be more powerful than his supervisor and wished he may forgive Protege.
When the Thing's soul was trapped in a place between life and death, the rest of the Fantastic Four located the Thing's soul and came across the One-Above-All, who restored the Thing back to life and promised to the team that new wonders would be discovered. When the Cosmic Ghost Rider was retconned into the story, the One Above All stated that the Rider was not one of his creations and denied him access to his room, leaving the Rider to talk to his actual creator who resembled Donny Cates and was also living in the same place as the One Above All. He then encouraged a grieving Peter Parker to keep his faith even in his Aunt May's death. When a bartender asks Mephisto about the nature of the Living Tribunal, the demon states that he is just the biggest kid in the playground compared to the principal.
After Thanos' reality of Earth-616 is destroyed, he and an alternate version of Adam Warlock come in contact with the One-Above-All, who existed outside time and space. Thanos convinces the being to restore Earth-616 in exchange for Warlock becoming the new Living Tribunal.
In the Avengers: No Road Home limited series, the Olympian goddess Nyx enters the One-Above-All's House of Ideas, with the Vision following after her.

One Above All (Celestial)

One Below All

The One Below All is the "dark reflection" of the One-Above-All, created by Al Ewing and Joe Bennett, and first appeared in Immortal Hulk #5 in the form of Bruce Banner's father, Brian Banner. Alluded to as the qlippoth, or "Hulk", of God, the One Below All is a malevolent and destructive force; when it speaks, it states that "I howl through many mouths. I break with many hands. They are themselves, but they are also me. I have all the power you give me and my weapon is hate.", in contrast to the One-Above-All's statement that "I see through many eyes. I build with many hands. They are themselves, but they are also me. I am all-powerful. My only weapon is love.".
The One Below All resides in the Below Place which is the deepest layer of Hell. It is the third gamma mutation's source of energy and is kept behind the Green Door. This was first dreamed up by Brian Banner. When it came to the day of a gamma bomb testing, the One Below All's powers were released when its detonation partially opened the Green Door and transformed Bruce Banner into Hulk.
Taking control of Brian Banner's ghost, the One Below All possessed Jailbait of the Riot Squad who lost control of her powers. When she died, her brother Hotshot had to hold a church hostage in order to perform the last rites of Jailbait. He claimed that Jailbait was possessed by the Devil. Then the One Below All possessed Sasquatch after he was killed in a bar fight. This drove Sasquatch on a feral rampage until Hulk defeated Sasquatch and drained the gamma energy out of him enough for Sasquatch to regress back to Walter Langkowski. The One Below All then went into Hulk's body. Brian's ghost was able to regain some control of himself and told Hulk about the One Below All's plan to get a host body.
The One Below All managed to gain control of Absorbing Man's body. When his soul encountered the One Below All, Absorbing Man was split in half as the One Below All took his body to the site of the first gamma bomb detonation where it opened the Green Door enough for New Mexico to plunge into the Below Place.
After Hulk and Bruce Banner split apart, the One Below All appeared in its cloud form as it prepares to take over the rest of Earth. When Hulk opposed its plan, the One Below All unleashed some demons on him. With help from Absorbing Man, Hulk was able to get the gamma energy that Absorbing Man gave him and was able to use his thunder clap to disperse the One Below All's cloud form and end his threat to the world.
Doctor Strange later spoke to Mephisto about removing the One Below All's possession from Hulk after the brief Defenders reunion. Mephisto states that the One Below All is far stronger than he is.
A flashforward to the end of the Marvel Universe shows the One Below All to have taken over the body of the Hulk and consumed the sentience of the cosmos, forcibly taking on the same role as Galactus for the next iteration of the multiverse and becoming the "Breaker of Worlds".
During the "Absolute Carnage" storyline, Bruce Banner had a theory that Knull can either be an aspect of the One Below All or a creature that it controls.

Emily Osborn

Emily Osborn is a supporting character in Marvel Comics. The character, created by J. M. DeMatteis and Sal Buscema, first appeared in The Spectacular Spider-Man #180. She was Norman Osborn's wife and Harry Osborn's mother.
She was apparently the only person that Norman ever showed love to, but their son's birth had weakened her with her dying sometime after. However, Emily turns up alive where she faked her death and poses as "Emma", a nanny hired by Liz Allan to be there for Normie Osborn and Stanley Osborn. She later took blood samples of her grandchildren for unknown reasons. During the "Go Down Swinging" storyline, Emily finds out that the Red Goblin is coming after their grandchildren. To keep Normie and Stanley safe, Emily abducts the two. Liz had tracking chips placed in the children as Liz, Mark Raxton and Harry find the children and discover that "Emma" is actually Emily. When the Red Goblin attacks, Emily gets away with Harry, Liz, Mark, Normie and Stanley while the Red Goblin fights with two Spider individuals as well as the Human Torch and Clash. When the Red Goblin defeats the group and catches up with the Osborn family, Emily witnesses the Red Goblin place a fragment on the Carnage symbiote on Normie. When the Red Goblin throws Emily through the window, she is saved by Spider-Man. Emily leaves the area with Stanley. Following the Red Goblin's defeat, Emily meets up with the rest of the Osborn family at Alchemax where she's forgiven for abandoning her family.

Alternate versions of Emily Osborn
