    The Heroes 


A bitter, sarcastic girl who once lamented being trapped in a suit to avoid poisoning everyone within range. The events of Murderworld cured Jennifer Takeda of her uncontrollable power, but has cost her the life of her boyfriend, Mettle and left her a changed woman.

Please see the Avengers Arena character sheet for that series' specific tropes about Hazmat, and also the Avengers Academy character sheet for the series she started out in.

  • Broken Bird: She's still deeply affected by Murderworld (not that she wasn't before, but Murderworld amplified it), and she nearly blasts a group of kids in the mall for bringing it up.
  • Heartbroken Badass: She still grieves for Mettle, but is still very formidable in combat, and now with her powers under control she's even more dangerous.
  • Heroic BSoD: The moment she met Arcade again she just blanked out. When she comes out of it she kills him.
  • In the Hood: Now that she's out the radioactive suit, she's gained a hoodie as part of her attire.
  • The Leader: Assumes this position on issue #5 when she proposes infiltrating the Masters of Evil, issue #8 solidifies this by having her call Hank Pym and starting to round up the Murderworld suvivors
  • Power Incontinence: Averted. She gained control of her powers, but it cost her just about everything else in her life.
  • Revenge: She kills Arcade in the exact manner he killed Mettle, or at least tries to.
  • To Be Lawful or Good: In issue #8 she notices that the villian lifestyle is easier to handle than the uptight superhero code, but she still has a solid belief on remaining on the good side.

Cullen Bloodstone

Cullen Bloodstone hails from the monster hunting Bloodstone family. He has a bitter and sarcastic demeanor which only falters when it comes to his love Anachronism, who is also his best friend. The events of Murderworld exposed his crush and the evil monster within him and driven a wedge between he and his best friend.

Please see the Avengers Arena character sheet for that series' specific tropes about Cullen and also his general Character page.

  • Brainwashed and Crazy: In issue #8, he's being mind-controlled by Hellstrom and forced to attack Aiden
  • Demonic Possession/Puppeteer Parasite: During his two years in the Klimtor dimension, he was possessed by a parasitic monster called a Glaratrox.
  • Mind-Control Eyes: When he's being controlled by Hellstrom, his eyes light up
  • Straight Gay: Cullen is gay and not the least bit stereotypical, with his hunting skills.
  • Token Evil Teammate: Cullen went off the deep end after the events of Arena and appears to have given into the dark side in him. He originally invaded Bagalia to get Arcade but joined up because he liked it there.Also, as of issue #6, he's the only one who doesn't know that the rest of the group is not joining the Masters of Evil for real.


Aiden 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. The events of Murderworld led to his first love Nara dying due to his best friend's action and he joins the team in infiltrating the Masters of Evil.

Please see the Avengers Arena character sheet for that series' specific tropes about Aiden.

  • An Ax To Grind: He seems to have gained a new Ax according to the source material.
  • Exact Words: When Hazmat tells him to "take the oportunity" as soon as he sees it, he kisses her by surprise
  • Evil Is Cool: In-Universe, he admits that he's starting to feel this way about Bagalia, and he's clearly disturbed by it.
  • Heartbroken Badass: After Nara died, he went into a Berserker Rage around Murderworld and still carries the grief into Undercover.
  • Leeroy Jenkins: Charges into a villain filled bar with no plan whatsoever despite knowing there's over a hundred people inside.
  • No Full Name Given: His last name is never mentioned in the story. According to Dennis Hopeless, his full name is "Aiden Gillespie".
  • Shapeshifter Mode Lock: He's seemingly stuck in warrior mode forever.

Death Locket

Rebecca 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. The events of Murderworld have changed her from the innocent young girl she once was.

Please see the Avengers Arena character sheet for that series' specific tropes about Rebbecca.


Cammi Benally was just an average girl living in Coot's Bluff, Alaska until a prison ship crashed in her town, carrying Drax the Destroyer. 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, only to end up in Murderworld shortly after returning to earth. She has chosen to go with the others in infiltrating Bagalia and the Masters of Evil.

Please see the Avengers Arena character sheet for that series' specific tropes about Cammi.

  • Badass Normal: She has no powers or cybernetics or magic. Just skill.
  • Out of Focus: Isn't seen for most of the second half of the series, due to her incarceration.
  • Screw This, I'm Out of Here!: Attempts this at the end of issue 5#, Constrictor says otherwise.
  • Token Good Teammate: She's the only one not interested in joining in with the villains and tends to try and point them towards the right direction.

Nico Minoru

The leader of the Runaways and witch who wields the Staff of One. After the events of Murderworld, she has joined the others in infiltrating Bagalia.

Please see the Avengers Arena character sheet for that series' specific tropes about Nico, and the Runaways character sheet for the series she started in.

  • Afraid of Their Own Strength: Alex has stated that despite her Witch Arm being a more powerful conduit for her magic, she's afraid of using it because her powers are so much stronger.
  • Black Magician Girl: She a witch who's fairly proficient with combat spells.
  • Despair Event Horizon: Seems to have hit it by issue 7 after Chase is critically injured and seemingly left in a coma.
  • Hair-Trigger Temper: Seems to have acquired this after Murderworld. Which is expected since irritability and outbursts of anger are common symptoms of Post Traumatic Stress disorder, one of the main topics of the book.
  • Sex with the Ex: Feeling guilty about Chase's comatose state, Nico and Alex rekindle their relationship and have sex. In Issue 8 it's revealed Nico and Alex are living in an apartment together and have been for three months. Nico and Alex appear half-naked and they're relationship is implied to be very... physical.
  • Shell-Shocked Veteran: Chase claims that she never really came "back" from her time in Murder World, even missing Molly's birthday.
  • Next Tier Power-Up: She was actually killed during the events of Arena, but was resurrected by the Staff of One and became even more powerful with black magic and with a new arm. She hesitates to use it unless she gets angry.
  • Working with the Ex: Now that Alex is back, they have this relationship with him teaching her battle strategy. It's... a miracle she hasn't killed him again.

Chase Stein

The oldest of the Runaways and owner of the world's most powerful gauntlets. After the events of Murderworld, he has joined the others in infiltrating Bagalia.

Please see the Avengers Arena character sheet for that series' specific tropes about Chase, and the Runaways character sheet for the series he started in.



A very wealthy psychopath, who enjoyed building Deadly Games (called "Murderworlds") for the X-Men. He was something of a joke villain until trapped 16 young Marvel superheroes in his own personal hellhole and had them kill one another. He has now joined the Masters of Evil in Bagalia.

Please see the Avengers Arena for that series' specific tropes about Arcade. See X-Men: Rogues Gallery A to I for general tropes.

  • Karma Houdini: For everything he did in Arena, he managed to not only win, but he got away unscathed. Until Issue #3.
  • Not Quite Dead: Despite Hazmat's attempt to kill him (in the same way he killed Mettle), he is instead made into a prisoner of the Masters of Evil.
  • Now What?: He feels hollow after Murderworld because he can't find a way to top it.
