Stain Changed Everything (What It Means To Be A Hero)

The Meaning of Heroism in My Hero Academia

The video argues that My Hero Academia separates being a hero as a profession from being heroic as a person. In a society where hero work is a career associated with status and success, the title can belong to people who don’t live up to its ideals. Endeavor—powerful and celebrated despite his abusive, self-serving behavior—is presented as a stark example.

Stain’s Test of Iida

Hero Killer Stain’s brief arc puts that contradiction under a spotlight. He believes heroes should act for others and targets those he considers selfish impostors.

Stain’s clash with Iida begins when he attacks Iida’s brother, Tensei. Stain initially treats Iida as a child, but turns on him when he realizes that Iida is motivated by revenge rather than by a desire to protect others. The video interprets Stain’s attempts to provoke Iida as a test of his true intentions.

Deku and Stain’s Ideals

Deku and Todoroki enter the fight to help. Deku’s declaration that “meddling when you don’t need to” is what makes someone a hero catches Stain’s attention. Stain sees genuine selflessness in Deku and even saves him from a Nomu.

Stain’s ideals also explain his respect for All Might—and his contempt for Shigaraki, whose destructive goals lack the purpose Stain believes a true hero or villain should have.

The Limits of Stain’s Conviction

Stain’s conviction doesn’t make him a hero. He claims authority over the meaning of heroism, refuses to believe people can change, and pursues his ideals through murder.

Iida eventually regrets acting selfishly and vows to do better. His change shows the possibility of growth that Stain’s rigid worldview denies.

Stain’s Influence

Stain’s influence also backfires. News of his defeat draws attention to the League of Villains, and people inspired by his ideology may join the group—even though Stain despises Shigaraki’s aims. His philosophy gains followers, but risks being distorted by them.

Meanwhile, Deku represents the video’s idea of a “true hero”: someone motivated first by helping others, not by fame or career success.

Outro

The narrator ends with a self-aware joke, admitting that his “true heroes” Patreon thank-you was cheesy because he forgot to script the outro.
