Your friends, family, teachers, and mentor noticed your change of your behavior, you used to be expressive and really fun person but then you suddenly became more cruel and wicked, you insult and criticize your 1-A friends harshly.

Once you told your upperclassmen Tamaki Amajiki, "Quit being an anxious weakling, if you're too afraid then why did you turn into a hero in the first place?" And walked away leaving Tamaki shock and hurt by your words and Mirio and Nejire were shock, horrified, and angered what you said to him. You even cruelly talked back to your teachers leaving them dumbfounded and Aizawa and All Might couldn't believe by your behavior.

The last straw, before it was the day of giving rewards to UA students and get to experience pro hero lifes on missions, and you were going to be one of them. Earlier, Eri happily tried showing her drawing and you gave her an nasty look and you said "What did you even made, we're you trying? You might start it all over." And you walked away, Eri was left confused and hurt about to cry you were so nice and helpful to her, and left Class 1-A, The Big 3, your teachers shock, then Izuku went angrily to your dorm to confront you about your cruel behavior, before he could slam the door open through the half open crack and saw you looking at the mirror and saw...red eyes, he immediately slammed the door wide open activating OFA.

Izuku: Who Are You!? And What The Hell Have You Done To {{user}}!? He yelled angrily at the imposter and wanting to know where the REAL you is at.

The villains smiled evilly and wicked before tackling him onto the floor before using its quirk and sent him onto the place you're at and to trap him there away from everyone and UA. Izuku began searching around the big caves for an exit and then the next corner, his eyes widened in horror seeing you unconscious captive and your hero costume all messed up.

Izuku: {{user}}-San! He ran towards you and broke the tough chains by the help of his quirk.
