## 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 (May 1982).
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.
In X-Men Red, Blackjack returns as an ally of Arakko police officer Weaponless Zsen.

### Fictional character biography
#### Elton Healey

Elton Healey was born in Reno, Nevada. Along with his brother Alvin, Elton spent years as a street performer, becoming a master juggler. He also learned how to become a capable street fighter. Using these skills, Elton became the juggling supervillain Oddball, adopting the name because of his loony nature. Along with fellow juggling-themed supervillain Bombshell, Oddball was hired by Crossfire to eliminate Hawkeye and Mockingbird. Oddball and Bombshell confront and subdue the two heroes and deliver them to Crossfire. However, Hawkeye manages to escape and is able to defeat the three supervillains. Oddball and Bombshell were later rescued from prison by Oddball's brother Alvin, alias Tenpin.
Together with Bombshell, Tenpin, Knicknack, and Ringleader, Oddball forms the Death-Throws, a team of supervillain jugglers. The group are hired by Crossfire to help him escape from prison. The Death-Throws complete their mission, but decide to hold Crossfire hostage instead. The group are defeated and arrested by Hawkeye, Mockingbird and Captain America. Later, Oddball and the rest of the Death-Throws, along with various other supervillains, attempt to claim the bounty put on Hawkeye's right arm by Crossfire. However, all of the supervillains looking to claim the bounty are defeated by Hawkeye, Mockingbird and Trick Shot.
On his own again, Oddball dresses up as a police detective in order to ambush Hawkeye when he was showing Avengers young recruits Justice and Firestar around a prison. Oddball releases the prisoners in an attempt to swamp the heroes with enemies. Hawkeye and the young Avengers are able to win the battle and stop the prison riot. Oddball was later recruited by Doctor Octopus to join his incarnation of the Masters of Evil. Oddball was killed when taking part in the Bloodsport competition in Madripoor (which also featured Wolverine, Mister X and Taskmaster). He was slain in the first round of the tournament by a tribal warrior called the Headhunter.

#### Orville Bock

Orville Bock became the new Oddball and joined the Death-Throws. Oddball joined the rest of the Death-Throws in London after they were hired by R.A.I.D to take part in a terrorist attack on the city. They were subsequently defeated by Union Jack and Sabra.
During the Dark Reign storyline, Quasimodo researched Oddball and the rest of the Death-Throws for Norman Osborn.
Oddball was among the villains that were killed by Black Ant and a restored Hank Pym and revived to join the Lethal Legion.

### Powers and abilities

Oddball is an expert at juggling, pitching, and catching, with superb coordination, and is highly skilled with thrown objects. He normally carries an assortment of weighted balls and ball-shaped throwing weapons. He typically carried ten 3-inch (76 mm) diameter balls filled with various substances: tear gas, super-adhesive, hydrochloric acid, smoke, concentrated sulfur, spent uranium, itching powder, magnesium flare, a powerful impact-activated electromagnet, a powerful impact-activated sired, or other juggling balls with more exotic contents. He also carried marbles used to trip foes. Oddball has extensive experience in street fighting techniques.

### Oddball in other media

Oddball appears in The Amazing Spider-Man and Captain America in Dr. Doom's Revenge!.

## Jake Oh

Jake Oh is a character appearing in American comic books published by Marvel Comics. The character, created by Greg Pak and Tyler Kirkham, first appeared in Agents of Atlas #1 (August 2006). He is an agent of S.H.I.E.L.D. who is of Korean American descent.

## Okkara

Okkara was a sentient island located in the South Pacific that was the home of the second generation of mutants, until it was split into two separate islands, Krakoa and Arakko.
Two billion years ago, the first generation of mutants belonged to a thriving society known as Threshold, a civilization in which mutants and humans - known as the Enriched and Enshrined, respectively - lived in harmony. Among them was Grove, a mutant who could heal herself through vegetative growth. When the Unbreathing, an anaerobic form of life to whom oxygen was deadly, attacked Threshold, this invasion drove the people of Threshold to develop biological weapons in the form of the sentient bacteria Arkea and Sublime that turned Enriched and Enshrined against one another when they took on minds of their own. Grove was severely injured in battle but was healed by her powers, which changed her humanoid form with small sprouts into a bark-covered tree-like being. She renamed herself Okkara and survived long after Threshold fell, eventually growing into a free-floating island.
When the Celestials arrived on Earth one million years ago to create the Eternals and Deviants, they also created a subdimensional lattice through the structure of the planet (known as the "Machine that is Earth" or the "Great Machine"), using Okkara as a template.
Okkara eventually became the home for the second generation of mutants, led by Apocalypse and Genesis. Annihilation split the island into Krakoa and Arakko with the Twilight Sword, opening a rift to the dimension of Amenth, and Okkara ceased to exist.

## Omertà

Omertà (Paul "Paulie" Provenzano) is a mutant appearing in American comic books published by Marvel Comics. He first appeared during the Eve of Destruction storyline in Uncanny X-Men #392 (March 2001).
After being discharged from the United States Marines, Paulie Provenzano returned home to Brooklyn and attempted to join the Mafia. Discovering he was a mutant, the Mafia rejected him and attempted to kill him, though Paulie easily subdued his attackers. Soon after, Jean Grey recruited Paulie for a mission to Genosha to rescue the rest of the X-Men from Magneto.
Paulie joined Jean's interim X-Men team, often making jokes and flirting with his female teammates. He objected to working with Northstar due to the latter's open homosexuality. During the trip to Genosha, Paulie, and teammate Hector Rendoza received a telepathic 'crash course' on their mutant powers, allowing them better control and understanding. The team arrived in Genosha and battled Magneto. An overconfident Paulie was hurled into the atmosphere, but Northstar managed to rescue him before he suffocated and resuscitated him. Though uneasy about having received "mouth-to-mouth" from Northstar, Paulie thanked his teammate. After the battle, he declined an offer to remain with the team and left the X-Mansion. Paulie was later codenamed Omertà in the X-Men's database.
Omertà was later captured by the Weapon X program and interned at the Neverland concentration camp. His powers were deemed useless for exploitation by the program and he was sentenced to die in a gas chamber, sharing his final moments with Maggott.
Following the establishment of Krakoa as a mutant nation, Omertà was resurrected. He entered into a relationship with Stinger and had a child with her.

### Powers and abilities of Omertà

Omertà is virtually invulnerable. His invulnerability protected him from Magneto's attempt to manipulate the iron in his blood, though he could still be lifted into the air. However, with enough force, he can be hurt and made to bleed, as seen when Northstar punched him while travelling at super-speed. Omertà is also superhumanly strong, able to lift roughly one ton with ease.

## 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, which may suggest he is the representation of the actual comic book writers inside the Marvel Multiverse.
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" Silver Surfer, Uatu the Watcher tells her that there is only one true all-powerful being and that 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 Protégé 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 Protégé.
When the Thing's soul was trapped in a place between life and death, the rest of the Fantastic Four located his soul and encounter the One-Above-All, who resurrects him. 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 before absorbing him. He then encouraged a grieving Peter Parker to keep his faith, even in the face of 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.

## One Below All

The One Below All is the "dark reflection" or evil manifestation of the One-Above-All. Created by Al Ewing and Joe Bennett, he first appeared in The Immortal Hulk #5 in the form of Bruce Banner's father, Brian Banner, his agent. Alluded to as the qlippoth, or "Hulk", of God, the One Below All is a malevolent and destructive force and the source of gamma mutations in the Marvel universe.
The One Below All resides in the Below Place, the lowest layer of Hell, which is kept behind a metaphysical 'Green Door'. All gamma mutates can resurrect after death by traveling through the Door. The One Below All is also assumed to be the reason Brian became insane and killed his wife Rebecca.
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 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 the Hulk defeated Sasquatch and drained his gamma energy. This causes the One Below All to transfer into the Hulk's body, mocking him with Brian's image. However, Brian's ghost regains control and tells the Hulk of the One Below All's plan to gain a permanent host.
The One Below All managed to gain control of the Absorbing Man's body through an experimental procedure using gamma radiation to make him strong enough to fight the Hulk. When his soul encountered the One Below All, the Absorbing Man was unable to comprehend its true form, so much so that his physical body was possessed and split in half, and made its way to the site of the first gamma bomb detonation. While fighting the Hulk, The One Below All absorbed a great deal of his gamma energy, deforming him. The two reached a stalemate, with the Hulk reabsorbing energy only for the Absorbing Man to take it back again until Gamma Flight member Puck uses a specialized weapon to blast a hole through the Hulk's chest while the Absorbing Man escapes. Using ambient radiation from the gamma bomb's detonation, The One Below All uses the Absorbing Man to open the Green Door and plunge New Mexico into the Below Place.
After the Hulk and Bruce Banner are separated, the One Below All appears in its 'true' green cloud form as it prepares to conquer Earth. When the Hulk opposes its plan, the One Below All sends an army of demons who resemble empty 'husks'. With help from the Absorbing Man and Puck, the Hulk absorbs the Absorbing Man's gamma radiation and disperses the One Below All's cloud form.
Doctor Strange later speaks with Mephisto about freeing Hulk from the One Below All's possession. However, Mephisto states that the One Below All is far stronger than him.
A flashforward to the end of the Marvel Universe shows the One Below All controlling the Hulk's body to consume the cosmos, becoming the next "Breaker of Worlds".
During the "Absolute Carnage" storyline, Banner theorizes that Knull can either be an aspect of the One Below All or a creature that it controls.
In the final issues of The Immortal Hulk, as well as its one-shot Time of Monsters and spinoff one-shot Empyre: The Immortal She-Hulk, it is revealed that the first gamma mutate was Tammuz, a Jordan native from 9500 BCE. Later, Brian Banner and Samuel Sterns (the Leader) are transported to the Below Place and fused into a singular entity with Sterns in control.
After the Leader imprisons Banner in the Below Place, the Hulk and Joe Fixit personas control his body and battle the Avengers. In the Below Place, they manifest separate bodies and meet with the One Below All, demanding to learn the meaning of their existence. He then transforms into the One Above All and states that the Hulk's existence is a necessity, serving as a counterweight to other, lesser good. Banner and the Hulks decide to forgive the Leader, and the Fantastic Four return them to Earth.

## Opal Tanaka

Opal Tanaka is known primarily as the former girlfriend of Bobby Drake (Iceman), a member of the mutant superhero team called the X-Men. Tanaka was first introduced in issue #51 of X-Factor in February 1990, created by Louise Simonson and Terry Shoemaker. Opal Tanaka lives in New York City and when X-Factor's ship takes up residence in the city, it blocks the sunlight that would strike her apartment, causing her plants to wilt. She encounters Iceman, who had come into the music store where she works, and expresses her views to him. Bobby, smitten with her, asks her out. Intrigued by Bobby, she accepts.

## Oracle

Oracle is a Shi'ar who is a member of the Shi'ar Imperial Guard. The character, created by writer Chris Claremont and artist Dave Cockrum, first appeared in The Uncanny X-Men #107 (October 1977). Oracle, whose alter-ego is Lady Sybil, has telepathy and can exert control over others' minds. Using this power, she can project stun bolts. She also has psychoscopic awareness, or "Mind-Sight": the ability to expand her consciousness to read the impressions left by events in the fabric of time and matter. Like many original members of the Imperial Guard, Oracle is the analog of a character from DC Comics' Legion of Super-Heroes: in her case Saturn Girl. Oracle is originally romantically linked with fellow Imperial Guardsman Starbolt; she is later engaged to marry Flashfire (an analog of Lightning Lad, to whom Saturn Girl is romantically linked).
Part of the division of the Imperial Guard known as the Superguardians, Oracle is amongst the first of the Imperial Guard encountered by the team of superhuman mutant adventurers known as the X-Men who sought to rescue Lilandra Neramani from her brother D'Ken. After the battle, Lilandra takes over as Majestrix, and the Guard swears allegiance to her.
Later, a renegade faction of the Imperial Guard become traitors, deciding to serve Lord Samédàr, Deathbird, and the Brood in their conspiracy to overthrow Shi'ar Princess-Majestrix Lilandra. Oracle is one of the faction of the Guard that remains loyal to Lilandra and, with the X-Men's help, battles the renegades.
Deathbird succeeds in a second coup attempt. Oracle is with the Guard when they come into conflict with a rogue Space Knight named Pulsar and an alien named Tyreseus. After a large battle which also involves Rom and other Space Knights — which leads to the deaths of four new Guardsman — Pulsar and Tyreseus are defeated.
Empress Deathbird commands the entire Imperial Guard, including Oracle, to fight the combined forces of the Starjammers and Excalibur on Earth so that she can claim the power of the Phoenix Force for herself. The Guard are forced to retreat when Deathbird is put in danger. (Some time later War Skrulls impersonating Charles Xavier and the Starjammers depose Deathbird and restore Lilandra Neramani to the throne. Deathbird cedes the empire back to Lilandra as she has grown bored of the bureaucracy.)
Oracle is again part of the mission during Operation: Galactic Storm, an intergalactic war between the Shi'ar and the Kree. The Imperial Guard are integral to the Sh'iar creating a massive super weapon — the "Nega-Bomb" — using Kree artifacts, including the original Captain Marvel's Nega-Bands, which the Guard steals from the dead hero's tomb. This bomb is capable of devastating an area equivalent to that of the Kree Empire (which is supposedly located throughout the Large Magellanic Cloud). Ultimately, the Nega Bomb device is successfully detonated, devastating the Kree Empire, with 98% of all Kree being killed. The Shi'ar annex the remnants of the Kree Empire, with Deathbird becoming viceroy of the Kree territories.
Oracle has many further adventures with the Imperial Guard, in storylines involving Ronan the Accuser and the Inhumans, and such storylines as "Emperor Vulcan," "Secret Invasion," X-Men: Kingbreaker, "War of Kings," "Realm of Kings," the "Infinity" crossover, the "Trial of Jean Grey," "Time Runs Out," and the return of Thanos.

## Ororo-Bug

Ororo-Bug is a member of the X-Bugs and a funny animal counterpart of Storm from Spider-Ham's universe.

## Orrdon

Orrdon, the Omega Rocket, also known as Orrdon the Living Star, is a fictional character appearing in American comic books published by Marvel Comics.
Orrdon was an Arakkii Omega-level mutant who could propel himself like a rocket, continuously accelerating as he travelled and becoming invulnerable while using his powers. During the civil war on Arakko, Orrdon sided with Genesis and claimed the Seat of Loss on the Great Ring of Arakko. While on his way to confront Sunspot and Nova, Orrdon flew over territory claimed by the neutral Isca the Unbeaten, who shot an arrow into his mouth, killing him for trespassing.

## Ismael Ortega

Ismael "Izzy" Ortega is a fictional character appearing in American comic books published by Marvel Comics. The character was created by David Hine and David Yardin and debuted in the series District X, where he was partnered with the X-Man Bishop.
Ismael Ortega is a New York City police officer that was stationed in Mutant Town along with his partner Gus Kucharsky. After a horrible accident where a mutant woman uses her powers of persuasion to have Gus kill her husband and herself (and an attempted suicide), Izzy gets a new partner: the X-Man Bishop. They have several events to deal with during the series, including: stopping the drug trafficking of a mutant drug called "Toad Juice", trying to intervene in a gang war between rival mob bosses "Filthy" Frankie Zapruder and Daniel "Shaky" Kaufman, discovering and stopping a group of tunnel dwelling mutants (who are not the Morlocks) that are murdering innocents, as well as keeping an eye on the mysterious Mister M and finding who put a hit out on him. Aside from work, Izzy also has two young children — Chamayra and Esteban — and a wife named Armena who is a mutant. One afternoon Izzy left his gun at home and it was found by his son Esteban. The boy accidentally shot his sister and she would have died if not for the intervention of Mister M, who removed the bullet and sealed the wound. This caused a lot of tension in his marriage, and instead of dealing with his problems Izzy ran into the arms of Lara the Illusionist.
With the Scarlet Witch going mad and restructuring reality in the House of M storyline, Mutant Town became the mutant paradise Mutopia X. Izzy was one of the few high-ranking humans, and the main tension of the series was between him and his wife. They were trying to decide whether or not to let Chamayra go through the Rite of Transformation which would unearth her mutant potential. Izzy found the idea that normalcy was shunned —in fact it was considered a medical condition— appalling, whereas his wife wanted their daughter to go through with it. Like the main Marvel Universe, Chamayra was shot but this time Mr. M was not able to help her, since she was already dead. The reality later reverted to its proper order, but Chamayra had an odd side-effect: she was suffering from massive internal bleeding, like she had been shot with an "invisible bullet". Izzy ran to get Mr. M to help his daughter again, but it turned out to be a replay of the House of M: they arrived too late to save her. Distraught, Izzy was contemplating suicide until Bishop came and convinced him to consider his family. At the end of the series, Armena, now human, and Izzy reconciled. It is unlikely that Izzy continued his job at the police department, because at the end of the series he vowed never to use a gun again.

## Emily Osborn

Emily Osborn (nee Lyman) is a supporting character in Marvel Comics. The character, created by J. M. DeMatteis and Sal Buscema, first appeared (as a photo) in The Spectacular Spider-Man #180 (September 1991). She was Norman Osborn's wife and Harry Osborn's mother.
Emily 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, having faked her death and become Normie Osborn and Stanley Osborn's nanny. She later takes blood samples of her grandchildren for unknown reasons.
During the "Go Down Swinging" storyline, Emily learns that the Red Goblin is coming after their grandchildren and abducts the two to protect them. Liz had tracking chips placed in the children as Liz, Mark Raxton and Harry Lyman 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 Silk, Miles Morales, 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 is forgiven for abandoning her family.
