ReptilThe dinosaur-morphing class leader of Avengers Academy who always aspired to be an Avenger. He's trapped alongside four other members of his team on Murderworld, and he wants to lead his team off the island and get back to his girlfriend. He also wants to avoid doing something he'll regret in order to protect them.Please see the Avengers Academy character sheet for that series' specific tropes about Reptil.
Collateral Angst: In #11, his point-of-view issue, the plot revolves around him trying to shake Hazmat out of her grief-fueled depression and denial and his frustrations at failing at it (and eventually just letting her do whatever she wants).
Good Thing You Can Heal: He's scarred up pretty bad after Deathlocket shoots him with her laser (under control by Apex). Hazmat made sure he healed fully by staying by his side.
Heroic Sacrifice: After he sees Hazmat about to go nuclear, he scoops her up with no hesitation and rushes her to the ocean to contain the blast. He may be dead after that.
If You Kill Him, You Will Be Just Like Him: He felt very badly about even thinking about killing Chase and Nico, he doesn't want to play Arcade's game, and just wants to get back home to his maybe-girlfriend White Tiger.
Love Triangle: As carry-over from Avengers Academy. It's still very complicated between Reptil, Finesse and White Tiger. Reptil was last dating White Tiger at Avengers Academy and possibly lamented being without her in issue #4, but in issue #10 it's revealed he may still have feelings for Finesse. On top of that, he doesn't know if his feelings are returned. Issue #13 reveals that Finesse still does love him.
Uncertain Doom: His final fate is uncertain. Hopeless said that as far as he is concerned, Reptil is dead but his fate is Left Hanging in case the character is to be used in the future.
HazmatA bitter, sarcastic girl who lamented being trapped in a suit to avoid poisoning everyone within range. As she attends Avengers Academy and becomes a hero, she comes to term with her powers, becomes more vulnerable and nicer (well, slightly) and even gains a boyfriend in Mettle. Murderworld is taxing her sanity and strength as she tries to survive while coping with tragedy.Please see the Avengers Academy character sheet for that series' specific tropes about Hazmat.
Break the Cutie: She's harsher than your typical cutie, but she's been through absolute hell while in Murderworld.
Failure Knight: : With Mettle dead, she doesn't want to lose another Academy member. In #4, she's first seen begging the others to keep looking for the missing Juston after they spent a day hunting and looking for clues to where his Sentinel crashed. She still feels guilty about them both and blames herself for getting Mettle killed.
Hair-Trigger Temper: She's always been quick to anger. And now, with Mettle dead, it's gotten worse with her ready to attack anyone outside the other Academy students. Including people she has met before like the Runaways.
Heartbroken Badass: Having Mettle killed in front of her hasn't diminished her fighting and hero skills. It possibly strengthened them due to her anger and grief.
Heroic BSOD: In issue #11, she loses it badly and just wants to enjoy the time she has left on the island in denial. In actuality, she is still grieving over Mettle, and wanted to just not think about him or Murderworld anymore.
Parental Marriage Veto: A sad carryover from Avengers Academy. It's revealed that Hazmat's parents disapprove of her relationship with Mettle.
Super Power Meltdown: She survives X-23's attack, but loses complete control of her powers and nearly causes a huge meltdown. Reptil rushes her to water and contains the blast, and Hazmat survives and is cured of her Power Incontinence.
X-23An Opposite-Sex Clone of Wolverine and trained assassin. She's served on the X-Men and even spent time on the X-Force, the X-Men's secret assassination squad. She joined Avengers Academy in order to rebuild her young life and do some soul-searching. Now she's thrown into Murderworld and trying to ignore her darker impulses.Please see [[Main/X-23 her character page]] for X-23's general character/series tropes.
Bald Women: During their fight, Hazmat nukes X-23 and in the process, completely torches Laura's hair. After the events on Arcade's island, X-23 is found wandering homeless by the O5 X-men and Laura's still totally bald.
Super Senses: X-23 is the most adept at surviving in extremes, and she's already using her senses to try to find out and look out for danger.
Sherlock Scan: Arena reminds the audience that when entering a room, X-23's brain automatically begins to calculate the best method by which to kill everyone in it. Her thoughts in her focus issue reveal that she can't turn it off, so she even does this with her friends.
Technical Pacifist: She tries not to resort to violence and only fights if someone attacks her or her friends. Sadly, this goes out the window if she smells the trigger scent.
The Worf Effect: Apex makes very short work of her with the Sentinel, establishing Apex's Arc Villain status. She later gets beaten by Cullen in his huge, raging monster form.
Unstoppable Rage: X-23 can fly into an Unstoppable Rage with a trigger scent, moving to seek and destroy anyone marked with it. The first few pages of Avengers Arena are a Flash Forward where she's in a rage attacking Hazmat.
Juston SeyfertOne of the few characters at Avengers Academy who doesn't have any powers. What he does have is a old model Sentinel, who is his protector and best friend. His sentinel, while making him a huge threat, also makes him a huge target in Murderworld.Please see the Avengers Academy character sheet for that series' specific tropes about Juston.
Break the Cutie: Juston was always a sweet kid, but Apex crippling him and being left in the desert for a week, has completely broken his spirit and made him angry enough to want to kill her.
Determinator: Managed to survive in the desert without his Sentinel, while crippled.
Despair Event Horizon: He knows he's one of the weakest on the island, due to him having no powers and Sentinel being destroyed by Apex. But he's motivated enough to take vengeance on Apex once he gets his buddy's body up and running again.
Roaring Rampage of Revenge: Goes on one against the ones who crippled him and his best friend: Apex and Deathlocket. Though he ends up being talked out of it, it ends up getting him killed by Apex.
Super Wheel Chair: He re-engineered his Sentinel as a pair of walking-legs to serve as a wheelchair.
Trauma Conga Line: With a missing mom and a sickly brother Juston's always had a hard life, but always maintained a positive attitude. Watching his Sentinel destroyed, getting left in a desert to die, and being crippled finally crushed him, nothing mention after that happened, he was killed. Even worse, it's revealed that his father did not want him to go to Avengers Academy.
MettleThe Big Guy of Avengers Academy. Despite his red iridium skin, huge physique, and scary skull face, Mettle is a absolute sweetheart. When transported to Murderworld, Mettle's gentle soul is tested, especially to see if he would do anything protect his girlfriend, Hazmat.Please see the Avengers Academy character sheet for that series' specific tropes about Mettle.
Black Dude Dies First: You couldn't tell by looking at him, but Mettle is African-American and Jewish. And he's the first causality of Avengers Arena.
Death by Sex: He and Hazmat had sex right before being transported to Murderworld.
Love Makes You Crazy: He tells Hazmat that maybe they should actually take Arcade seriously. When Hazmat tells him she's not bowing down to a villain, Mettle says that he doesn't care if anyone else dies, just so long as she doesn't.
Ludicrous Gibs: What Arcade reduces him to, just by pointing a finger at him.
Of Corpse He's Alive: Arcade actually reassembles his skin after he explodes, and has him walking around as a husk in order to lure Hazmat and X-23 into a trap.
Chase SteinChase is a complicated boy: he's smart but lazy, friendly but prone to anger, very open but keeps secrets. He's transported to Murderworld along with Nico. He's survived battles against gods, killer robots, aliens and other things, but in Murderworld, he's afraid he'll survive again.Please see the Runaways character sheet for that series' specific tropes about Chase.
And I Must Scream: Apex used her technopathy to control Chase's Darkhawk armor, so he was completely helpless when she used him to kill Nico.
Failure Knight: Since losing Gertrude, he has now transferred all of his energy into protecting Nico in Murderworld.
Mind Manipulation: Was under Apex's control for a bit, while still in the Darkhawk armor.
Pragmatic Hero: He didn't want to do it but he rationalized killing Tom to save the group and Nico if it meant finishing off Apex.
Remember That You Trust Me: Between him and Nico, stemming from issues dating back all the way from the second volume of Runaways. Nico still finds it hard to trust Chase completely, and within Murderworld, this is exacerbated. It doesn't help that he hid the fact that he had the Darkhawk armor and thought killing Tim/Apex was a reasonable solution. He was right in hindsight, but it still disturbed her.
Survivor Guilt: Being in Murderworld has brought his guilt over Gert back to the surface.
Verbal Tic: Chase sometimes says "Yo" when he speaks, something Cammi makes fun of in #17.
Nico MinoruNico is the leader of the Runaways, who still has doubts about her leadership skills. She has a no-nonsense personality and an aptitude for magic, but with her powers on the fritz she may be less powerful than she previously was. Despite this, she's determined not to play into Arcade's hands.Please see the Runways character sheet for that series' specific tropes about Nico.
An Arm and a Leg: Not only does she get her leg broken by Apex controlling Sentinel (complete with a gruesome shots of her leg bone sticking out), she gets her arm completely blown off by a mind-controlled Darkhawk before getting kicked down a incline.
Back from the Dead: After she was killed, she was resurrected by the Staff of One by a death rattle spell.
Beware the Nice Ones: Being killed, and then resurrected affected her and she's done playing nice. She actually orders Chase to attack Reptil, and then later she attacks a bleeding Cullen.
Break the Cutie: All she went through including getting brutally killed pushed her to the point at which she would willingly kill Apex.
Came Back Strong: After her resurrection, she gets new hand that allows her to cast spells without Staff of One and would the staff be taken from her, she can now summon it back at instant.
Heroic Sacrifice: She sets up a teleportation spell for the others, and closes it off after she gets injured to prevent Apex from following them.
Power Incontinence: Her magic isn't working as strongly as it should, due to the effects of magic inhibiting nanites scattered in the air. All her escape spells failed and she had to cut herself several times in order to get one particular spell (creating a food tree) to work the way she wanted it. Combat and rescue spells work unhindered, however.
Redemption Equals Death: She felt terrible about Apex killing Juston and getting away. She steadfastly defends the crew against Apex and the Sentinel to make it and makes sure the others escape quickly.
These Hands Have Killed: Part of her jumping on the bandwagon to start killing the other teens was that she thought that she killed both Apex and Deathlocket, and it didn't matter what she did next.
You Shall Not Pass: She held off Apex and her small horde solo while everyone else dealt with the unconscious X-23, only running on her word to.
From the Braddock Academy
Kid BritonA young Alternate Universe version of Captain Britain/Brian Braddock. At Braddock Academy, he was a cocky bully who threw his weight around and few dared challenge him. With his confidence being the source of his power, he's confident he has what it takes to survive Murderworld.
Alternate Universe: He is a younger version of Captain Britain in a different universe, who has saved his universe several times.
Break the Haughty: Apex causally mentioned that she knew all along he was cheating on her and basically let him do it and he played into her hands. He is quickly unnerved by this (his displayed Life Meter actually goes down a few), and later gets hurt by Nara which freaks him out more.
Jerkass: Arrogant, bullying of the other students (mainly Anachronism) among other misdeeds.
Jerk Jock: Fills this role at the Braddock Academy.
The Leader: He is the School Idol at Braddock Academy for both right and wrong reasons. He is a genuine hero who's saved his world, but he is also a bully. He quickly takes initiative to grab the leader position of the Braddock kids in Murderworld.
Nominal Hero: He's a hero who fights on the side of good, but he only does it to boost his own ego and powers.
Off with His Head!: After threatening Nara and cutting her, Anachronism finally uses his axe to decapitate him.
ApexShe only has the ability to fly, but Katy Bashir makes up for it in her intellect, craftiness, and ruthlessness. She is all too eager to start playing Arcade's game in order to save her skin. Despite her supposedly weak powers, Apex may be the biggest player in Murderworld. She has a twin brother named Tim that she shares the same body with, that due to genetic manipulation by her parents. She and Tim are also technopaths, something else Apex kept secret.
Angsty Surviving Twin: Subverted, she caused the car accident that injured her and used that opportunity to completely suppress Tim.
Arc Villain: Throughout the "Game On" arc before she's defeated by Nico.
Bollywood Nerd: She's of Indian ethnicity and she says herself that she's smart as a whip. Most of her intellect goes into manipulating people and deceit.
Jerkass: Proud of her manipulations of people, blatantly using them and taunting Juston, who she earlier crippled, before snapping his neck really pushed her over the edge. She also taunts Nico as she uses Darkhawk armor-clad Chase to cut her down.
The Lancer: She dated Kid Briton who's The Leader and complimented his strength and power with her cunning and intelligence. It turns out she more than evenly matched for him and after he dies, she becomes the biggest threat in Murderworld.
Manipulative Bitch: She calls herself out on this in a calming way in #2, saying she can talk others into doing what she wants casually. She had Brian under her thumb as well as Death Locket. She's also literally a manipulative bitch, as with her powers she can control technology, which is bad news for cyborg Death Locket.
Meaningful Name: Her super-name means "the top, the peak, the summit", and she does think very highly of herself compared to her peers. Not to mention it is a reference to electronic musician Aphex Twin, as she is a twin.
Motive Rant: In which she tries to convince herself that she's actually the hero by going out and killing others.
Pragmatic Villainy: All of her actions in the game are primarily to survive and to come out on top.
Polar Opposite Twins: Katy is destructive and manipulative and Tim is gentle and understanding. Tim teaches Deathlocket to use her arm cannon, Katy simply takes over her mind.
Smug Snake: She's very proud of her herself, arrogant, and thinks she's the smartest person in the room. She even thinks of herself as a hero for her murderous actions on Murderworld. Eventually, it becomes her downfall and she is killed by Deathlocket.
Technopath: Both Katy and Tim are technopaths. She's been controlling Deathlocket's random attacks since the beginning, and can also take control of Sentinel.
Tragic Villain: She's the furthest thing from a hero, but she hates Arcade as much as anyone in Murderworld. However, she also wants to survive which leads to her murderous streak in the "Game On" arc. Somewhere in-between #12 and #16, when she releases her repression of Tim (or lost that ability) and starts being helpful in trying to take down Arcade. Of course, she went back to betraying the heroes in exchange for Arcade editing the footage so that she came out looking like a hero.
Walking Spoiler: The whole sharing-a-body-with-her-twin-brother thing is a pretty left-field twist no one saw coming, and if you were to look up a character bio or more information on Apex, you would instantly be spoiled for a huge twist.
Cullen BloodstoneCullen Bloodstone hails from the monster hunting Bloodstone family. While he may be small, he's fairly smart and resourceful with a sharp tongue ready with a quip. He has his friend Anachronism watching his back, however Cullen hides the fact that he has feelings for him. Cullen also hides the fact that he's possessed by a huge Eldritch Abomination-type monster.
Accidental Murder: He kills Nara inadvertently through the uncontrollable parasitic monster possessing him.
Hopeless Suitor: Unfortunately for Cullen, Anachronism hasn't noticed his crush at all.
Incompatible Orientation: Cullen is gay, Anachronism is presumably straight and infatuated with Nara much to Cullen's chagrin.
Parental Abandonment: For Cullen's birthday, his father left him in a monster-filled dimension for what was meant to be a few hours for training. But Ulysses was killed soon after and Cullen was left behind for more than two years. He also was angry with Elsa when she left him at the Braddock Academy, but that was for his own good.
Superpowered Evil Side: Cullen is possessed by a huge, ugly green monster that his bloodstone ring holds back.
AnachronismAiden was a chubby gamer nerd who was constantly picked on at Braddock Academy. Somehow, he inherited the body of an immortal Celtic warlord complete with a huge axe, but he still has his pacifist nature with him. In Murderworld, he struggling with the bloodthirstiness and still trying to resist the urge to kill.
Ax-Crazy: No pun intended, but he tries his hardest to control this side of himself. He still finds himself smiling while in life or death situations.
An Axe to Grind: Anachronism's main weapon is a huge battle axe. Which he may or may not be afraid of using.
Missing Mom: In his narration for issue #6, he mentioned his mother walked out on him and his father.
Morality Pet: To Nara, which makes her more relatable and less violence/sex-crazed.
Oblivious to Love: He has not noticed Cullen's crush on him, most likely because he's distracted by Nara, not to mention being infused with a Celtic warrior. Nara finally clues him in that Cullen has it bad for him.
Split Personality: Aiden's docile nerd personality was meshed with the warrior's savageness, and he tried to keep it under control. Nara suggests that the savageness is Aiden's own hidden dark side taking shape, now that he has the power to deal with bullies.
Unstoppable Rage: After Cullen kills Nara, he gets very angry and cuts Cullen with his ax, and then kicks him in the head in retaliation.
Violent Glaswegian: The Celtic warrior that possess Aiden. Possibly Aiden himself (as he is Scottish), whether or not he wants to admit it.
NaraA girl hailing from the Marvel Universe's version of Atlantis. She's mean, cruel, and not afraid to do anything to get what she wants. In addition to her violent streak, she's also very voluptuous, and a temptress to all the boys at Braddock Academy.
Action Girl: Just like all the other girls in the Murderworld, outside Apex.
All Amazons Want Hercules: She is strongly attracted to aggressive and violent people. She thought it was pretty hot watching poor Aiden being beaten up by Kid Briton.
Blood Knight: She loves watching violence, and also participating in it, regard less of the reason.
The Chick: She functions as the emotional/social one of the Braddock group. She encourages Anachronism to embrace his dark side and show his strength, while sexually teasing him. In time, she grows to care for him and acts in a true Chick manner by reminding Anachronism that Cullen was trying to protect him by unleashing his monster form.
The Vamp: She's a big seductress at Braddock Academy, not just getting Kid Briton under her spell, but also Anachronism.
Other Teen Heroes
Death LocketRebecca Ryker was a ordinary girl who's world turned upside down when a Deathlok (a re-animated cyborg) showed up at her house one day and killed her mother, brother and tried to kill her as well. She survived, but her father (Harlan Ryker, cybernetic genius and a creator of Deathlok) had to transform her into a cyborg in order save her life. Rebecca is innocent young girl who doesn't mean to hurt anyone, but there's no room for nice people in Murderworld.
Ambiguously Brown: She's browner-skinned than the white kids of Arena, and her name is not indicative of any ethnicity.
An Arm and a Leg: She was missing one arm and one leg that we replaced with cybernetics. Then in Murderworld, Nico disassembles her cybernetic arm after she is resurrected. Tim fixes it, but then it's broken again by Arcade.
Break the Cutie: Her backstory has her seeing her mother and little brother murdered by a Deathlok cyborg that time-traveled to killed her father Harlan Ryker, who created them. She gets caught in the explosion that killed her mother and brother. Her father transforms her into a Deathlok to save her life. And then her father is taken to jail, and just when she wakes from her coma and finds out she's a cyborg, she's transported to Murderworld. You can also add being controlled by Apex into shooting at the heroes, not to mention killing her first love to the list.
The Cutie: Deathlocket is very sweet and friendly, which is remarkable considering the circumstances.
The Ingenue: Deathlocket is completely new to the superhero world and very naive, which leads her to be taken advantage of in Murderworld by Apex.
CammiCammi Benally was just an average girl living in Coot's Bluff, Alaska until a prison ship crashed in her town, carrying Drax the Destoryer. From there, she becomes fast friends with Drax, escapes Earth into space with him, and gets involved in an interstellar war. She and Drax are separated, and from there she's spent months in space, surviving on her own. Her survival skills are top-notch, but she may have to play nice with others to survive Arcade's game.
Action Survivor: She has no special powers outside of her weapons but she's the most adept at surviving in extreme conditions and a formidable opponent.
Awesomeness by Analysis: In addition to her survival skills, she can accurately read people's emotions, due having use those skills in outer space. She correctly guessed that Cullen likes Anachronism.
Badass Normal: She has no superpowers, but managed to live in deep space alone (a fact that shocked S.W.O.R.D. leader Agent Brand), and handles herself well on the island. Temporarily became the new Darkhawk, but gave it up after an issue.
Crazy Survivalist: Not just in space but in Murderworld, she's already set up traps and routinely scouts the area.
I Just Want to Be Special: She hates just being a non-powered human, to the point of rejecting going back to Earth to avoid punishment.
I Owe You My Life: Because Nico saved her and the whole group from Apex controlling the Sentinel and Deathlocket, she feels that she needs to repay her and tries to convince her not to kill anyone else later in the game.
The Nicknamer: She comes up with cutesy nicknames for just about everyone. She even dubbed Anachronism "Axbro", the Ascended Meme from around the fandom.
Old Soldier: Compared to most of the kids stuck on Murderworld, she has the most hero experience and can survive on her own. She also takes a bit of a mentor/leader role amongst the other players.
Only Sane Man: She is the only teen thinking long-term strategy and survival and she took up for Nico, even after she let Apex get away and Juston got killed. She tries desperately not to fall into Arcade's trap, but the other kids around her are willing to play the game.
Precocious Crush: She reveals in #14 that she did fall in love with Drax, even though she was 10 at the time. Now that she's a teenager, she may have had the time to reflect on it and figured out that she did love him.
DarkhawkChris Powell was an ordinary high school student before he found an amulet that transformed him into a superhero with cosmic armor. Through the years, he's been fighting crime on his own and even team up with a few superhero teams such as the New Warriors and the Loners. Now in his 20s, he's still considered to be a teen superhero and is trapped on Murderworld but he's determined not to play Arcade's game and look out for the other teens.Please see his character page for Darkhawk's general character/series tropes.
Adults Are Useless: He is the only adult player in Murderworld, and he's taken out fairly early and plays no role in the book until the final issues, in which he's incapacitated again.
Deus Exit Machina: Since he's the most powerful person in the Arena, Darkhawk's amulet gets stolen in the third issue and he gets knocked out. While he isn't dead yet, he's depowered and alone in a jungle while someone runs around in his armor. Later when he revives, Deathlocket (controlled by Apex) takes him out.
Not Quite Dead: Issue #16 confirms he's alive. He was just captured, but freed by Deathlocket. He gets shot by her an issue later though.
The Last of These Is Not Like the Others: All of the heroes in Murderworld are young heroes in their teens. Except for Darkhawk, who's in his mid 20s by now. Cammi even points out that he hasn't been as young as the rest of the competitors since he was in the New Warriors.
Red RavenDania is a young girl who is part of the Bird-People (descended from The Inhumans), and the daughter of the original Golden Age Red Raven. She's trapped in Murderworld with 15 other kids and she's hoping to live and make an impact, just like her father.
Back for the Dead: It had been years since the last time this hero was used only to be killed off.
Legacy Character: The third character to be called Red Raven, and daughter of the first one.
Red Shirt: Red Raven, as she shows that trying to fly out of Murderworld probably wasn't the best idea. Bonus points for her also wearing red.
And I Must Scream: Several years ago, Apex caused a car accident and took the opportunity to take over the body both she and Tim share. For years, he was trapped in her mind while she lived life without him.
Extreme Doormat: Childhood psychologists described him as a "people pleaser" and "non-confrontational." Even before he was trapped, he never in any way tried to confront Apex about her behavior. He knows that stopping for good would lead to his death.
Gender Bender: The body he shares with Apex switches from female twin to male twin every other day.
I Cannot Self-Terminate: Tim realizes the solution to stopping Apex, but he would have to commit suicide. But he was too scared to do it, and by the time he realized what he had to do, Apex took over and he was trapped in her head once again.
Kill Us Both: Tim pleads for Deathlocket to kill him in order to stop Apex. After hesitating, she does it.
Polar Opposite Twins: Tim is docile and non-confrontational, compared to the scheming, manipulative Apex.
Walking Spoiler: If you highlight any of that text, you would spoil yourself for a huge twist.
ArcadeA very wealthy psychopath, who enjoyed building Deadly Games (called "Murderworlds") for the X-Men. He was something of a joke villain, as he never managed to kill any super hero in his games once he started targeting them. But now, he has somehow gained omnipotent power and has created his deadliest game ever, and trapped 16 young Marvel superheroes in his own personal hellhole.
The Bad Guy Wins: He gets his desired results, and puts the Murderworld footage on the internet, immortalizing him as a true villain.
A Glass of Chianti: He casually enjoys a glass of wine, right after the third causality and first hero-on-hero murder happens in issue #6.
A God Am I: As he stated in the first issue: "I'm not the villain, here. I am God."
Bad Boss: Tries to kill both Ms. Coriander just for fun and kills his Robot Buddy Locke for questioning his plan.
Clothes Make the Superman: Arcade's new suit courtesy of Ms. Coriander uses advanced technology that grants him superpowers in Murderworld. Thanks to the suit Arcade can manipulate the environment of Murderworld at will, and see everything happening in it. Ms. Coriander claims that as long as he's in Murderworld, Arcade could give Thor a run for his money.
Hubris: Arcade's main character flaw. He was an expert assassin who got bored and hampered himself with elaborate deathtraps (and then by targeting super heroes) to give himself more of a challenge.
Not-So-Harmless Villain: Arcade was something of a joke villain, as he never killed anyone with his traps and has no superpowers of his own. In this comic however, he mysteriously gained God-like powers and turned himself into a major threat. He actually lamented his previously known status and relishes in his new power.
People Jars: The last page of issue 12 reveals that he's placed several fallen contestants into them.
Selective Obliviousness: Arcade's use of powers compared to how the suit works. Ms. Coriander tells him that he works best manipulating people to off themselves in #7. What does he spend #1 doing? Being a 'super powered thug' (which Ms. Coriander was trying to have him avoid becoming) to the point where he notes that he's bullying the kids.
The GM Is A Cheating Bastard: Arcade is manipulating the environment to suit his own ends. He teleports half the Braddock Kids to the other half's location after betrayal splits the group.
In issue #7, he admits to his assistant Ms. Coriander that he's always been like this. All his talk of sportsmanship and fair play is just that: talk. This is only a partial Retcon. He cheated like no one's business back in the day, but never begrudged losing until recently. In other words, he had sportsmanship, but was never fair.
Ms. CorianderArcade's primary architect and builder of the new Murderworld.
Hypercompetent Sidekick: To Arcade. Arcade becomes unnerved by this and tries to kill her. She knew he'd try that so it didn't work.
Locke: "I've been meaning to ask, sir ... What is the preferred end result here?''
Locke: "Of course, but to [restore your reputation] you must reveal what's happened. And when you do, you' will instantly make mortal enemies of the world's most powerful beings. The Avengers ... the X-Men ... coming after you all at once. I see only two possibilities. That you are committing suicide by cape or you are actually delusional enough to believe you can get away with it.
Arcade: You've overlooked a third option. A little theory I like to call ... SHUT YOUR FILTHY ROBOT MOUTH!
