The series follows the survivors of Avengers Arena (minus X-23, Reptil and Darkhawk) - Nico, Chase, Hazmat, Cammi, Death Locket, Cullen Bloodstone, and Anachronism - as they try to infiltrate the Masters of Evil.

Death Locket is once again being held prisoner by S.H.I.E.L.D., but she escapes thanks to a sympathetic agent who helps her cope with her ever-evolving cybernetic implants.

Cullen Bloodstone had dropped out of the Braddock Academy and become obsessed with killing Arcade, ultimately tracking him to Bagalia.

[2] The heroes teleport to Bagalia in disguise and locate Cullen at the Hole (a Bagalian bar that is owned by Arcade).

Constrictor and Madam Masque arrange for Cullen to teleport the group to a nearby swanky party at Massacrer Casino hosted by Arcade so that they can get revenge on him once and for all.

[3] Baron Zemo, Madame Masque, Constrictor and Daimon Hellstrom watch as the heroes try to avoid being killed as Arcade has arranged the party at Massacrer Casino as the testing grounds for his newest version of "Murderworld": fancy parties at Casino where the rich and powerful can try and kill each other to prove their supremacy.

detention center, Karolina Dean, Molly Hayes, Finesse, Striker, Elsa Bloodstone, and several unnamed parents come to visit the group.

After Cammi has a touching moment with her mother, Daimon Hellstrom teleports the lair back to Bagalia where Baron Zemo offers the group a chance to join the Masters of Evil.

Daimon Hellstrom takes Nico Minoru and Cullen Bloodstone into Hell Town, a four block district that contains all of the Masters of Evil's magic.

Daimon Hellstrom quotes "But if you wanna know why that kid up there roasting in hellfire seems happy while you’re clearly inside out miserable, that’s simple.

While Chase, a natural athlete, plays basketball with the muscle of the Masters, Death Locket is getting the lowdown on how this portion of the group works.

Back in Hell Town, Nico Minoru blows some steam by fighting demons in Mephisticuffs and totally loses it in a big way.

The group (except for Death Locket and Bloodstone) comes together and mostly agrees to join with the purpose of secretly bringing the Masters of Evil down.

During the fight which is a ground skirmish against A.I.M., it is revealed that Death Locket has developed a crush on Excavator and parachutes in to the island.

Before the Young Masters can achieve their objective, a random missile robs them of their entryway upon the arrival of Captain America.

[8] Later on, Mazmat and Aiden finally start a relationship and Madame Masque is so enamored that she involves the young couple in her plans.

[9] It also turns out that Death Locket had no plans of returning to the surface, since she likes Bagalia and is romantically involved with Excavator.
