(Kaiden is seen at Combat Class as he is ready to face his opponents: Team CRDL. Russel charges at him, but he dodges the attacks with his semblance: Shadow Step, and appears behind him. As Russel tries to stab him, he counters with a quick strike that knocks him out.)

Kaiden: That's it? So much for superiority complex...

Glynda: Russel Thrush is out.

(Dove charges at Kaiden, who dodges his attacks, but then he stops dodging and parries his attacks like they're nothing.)

Kaiden: Wow, this is freakin' boooooriiiiing...

(Kaiden then punches Dove in the gut, making him cough blood as he falls down. Sky tries to attack Kaiden, who makes a quick work on him and punches him multiple times, destroying his weapon, his armor and his aura. This made Cardin furious as he tries to swing his Executioner at him, but Kaiden socks him in the face and breaks his weapon before using his semblance to beat him multiple times before knocking him out.)

Kaiden: You're lucky we're in Beacon. Or else, I wouldn't be so merciful.

Glynda: The winner is Kaiden Grey.

(Everyone starts cheering Kaiden, who defeated Team CRDL with ease.)

(Timeskip)

(Kaiden is seen at his dorm, but he saw the news of Roman stealing another Dust Shop, and decided to do something about it. He places a device on his wrist and prepares to transform.)

Kaiden: Access... FLASH!

(Kaiden transforms into Gridman Sigma, and goes to stop Roman and his henchmen.)

(Elsewhere, Roman is seen finishing his stealing as he suddenly gets hit by a drop kick, and is sent sprawling as he turns to see Gridman Sigma in his human size.)

G. Sigma: Stealing dust again, Torchwick?

(Roman groans as he gets up and sees Gridman Sigma.)

G. Sigma: As long as I am here, the forces of evil shall not prevail!

(Roman growls as he snaps his fingers, and his henchmen come in.)

Roman: (stern) Waste him!

(One of them charges at him, but he grabs the henchman and slams him down. He then kicks three of them, and pushes the fifth henchman before dropkicking the last henchman. Roman then aims his Melodic Cugdel at him, but Gridman Sigma shoves it with a chop before hitting him two times. Roman grunts in pain as Gridman Sigma punches him three times, and he crashes into a building.)

G. Sigma: GRID SIGMA BEAM!

(Gridman Sigma blasts Roman with his beam, knocking him out cold before using his fixer beam to repair the damage as he starts flying away, and then the police takes Roman away.)
