-- Mettle


One day while Ken Mack was surfing, another surfer accidentally crashed into him, ramming Ken's face with his surf board. Instead of killing him, the impact trauma accelerated a transformation already taking place under his skin. His skin peeled off, revealing a red iridium skull beneath. [3]

Ken's skull

At the time of the accident, Ken was unaware of the transformation because the iridium has no nerve endings. He was then taken to Norman Osborn on a plane. Norman then amplified his transformation, making his whole body iridium.

Avengers Academy

Ken is then recruited to join the newly formed Avengers Academy alongside other young potential heroes Veil (Madeline Berry), Striker (Brandon Sharpe), Finesse (Jeanne Foucault), Reptil (Humberto Lopez) and Hazmat (Jennifer Takeda). At their first meeting Veil screams when she sees Mettle for the first time. But he is not offended as he is used to being feared, during the first few days at the school he bonds with Reptil and they become friends. He, and the rest of the class were lead to believe they were among those most likely to become heroes, but they quickly uncovered files on them revealed they were most likely to become villains. [1]

On their visit to the Raft Mettle, Hazmat and Veil went to Norman Osborn's cell. Mettle and Hazmat are looking forward to killing Osborn, much to the shock of Veil, who thought that they were going to force him to change them back to normal. Hazmat states that if Pym cannot save them, no one can. The only thing worthwhile is making Osborn pay for what he has done. Grabbed at the neck by Mettle, Osborn tells them that he has molded them for greatness. He subtly manipulates them into thinking that perhaps Pym is withholding his attempts at a cure. [4]

They then accidentally run into Powderkeg, who is in the middle of fighting the Academy staff. They are knocked away and them they come to, Mettle impulsively attacks the Juggernaut, before he realizes what he had done. Veil then alerts them to Man-Thing being present. Knowing that his teammate would burn them no matter what material they are made of, Juggernaut uses a loud clap to blow Veil away from the creature, before carting him off back to his habitat. Mettle and Veil then go looking for Hazmat, who is in the midst of wandering in a fight among The Raft guards and prisoners. Grizzly attempts to take her as a hostage, only to back off when she threatens to give him cancer. However, she is knocked out by another prisoner. Her friends soon find her and Mettle decides to face the villains alone, only for their teachers to intervene.

Once The Raft is brought under control, Luke Cage scolds the trio for attempting a shot at Osborn. Hazmat states that he does not know what that madman did to them. Cage retorts that Osborn put a bomb on his heart and went after his wife, but he is not the type to tear off his cell door. Pym promises to discipline his students and to upgrade prison security. Mettle, Veil and Hazmat silently agree to keep the true cause of the blackout a secret, as Mettle contemplates what they've almost done. [3]

Later the team goes out, with Mettle and Hazmat shrunk onto Wasp's hand. Whirlwind then appears and attacks a guy. The team use their powers to defeat Whirlwind, but become public. [5]

Reptil has been elected class leader of Avengers Academy. Reptil decides to mediate Mettle and Hazmat's differences, saying that they make a good couple, they become disgusted.

Pym discovers Veil in her attempt to bring back the Wasp. However, it turns out that what they perceived to be Janet is actually Carina Walters. And where she is, Michael Korvac is as well. However, Carina has no intention of returning to her husband. The Avengers and New Avengers then arrive in the Academy to defeat Korvac once again. Meanwhile, Jocasta sequesters the Academy students and Carina into a saferoom which shunt to other dimensions every 2.3 seconds, though the effort is futile.

Carina tells the students that Korvac is not invincible and cites the example of how the Red Skull disintegrated him with antimatter. She offers to place them in the bodies of their adults selves from other timelines, but only if they consent. Korvac floors the Avengers with only Speedball is left standing. Academy students step out as adults to face him.[9]

They then attack Korvac, who has already floored the Avengers. Veil, Finesse, Hazmat and Reptil catch him by surprise. Mettle punches Korvac through the chest and thinks that they achieved an early victory. But Korvac gets up and fires and energy beam through Striker's chest. Luckily, because it's his adult self who has died, Carina restores Striker to his teenage form. Scared, Striker runs off.

Carina then turns to Veil and Hazmat, stating that they two of them are key to Korvac's defeat. Meanwhile, Korvac decides to no longer hold back, believing that Carina thought that he would refrain from killing the students to avoid damaging the timestream. He boasts that once he's won and conquer all existence, he will then then repair the damage. Hazmat then walks up, revealing that her older self can she can generate antimatter and defeat Korvac. Carina congratulates the students on a great victory, before restoring them to their original bodies.

Pym asks Carina if she can use her power to help Mettle and Hazmat. However, she admits that she has less than finer control of them. She then leaves, inferring that he may find Janet one day.

Mettle finds Hazmat in the students lounge. He tries comforting her, even advising that she can take her helmet off around him. With some reluctance, Hazmat does so and cries in his arms.[10]
