Sports Festival Arc
Stain is introduced after killing Ingenium. In the same area as the deceased Ingenium, Stain is disgusted by the fact that Pro Heroes call themselves "Heroes", saying that they are not worthy of being Heroes. Stain declares that there is only one person that is worthy of being called a Hero. After stepping into the light, Stain claims that the only person who is worthy of being called a Hero is also the only one who is allowed to do him in and that Hero is All Might.

Stain appears again on a rooftop, saying that the current society is distorted and twisted and declares that he will make them face reality.
