Warning: contains spoilers for My Hero Academia chapter 330!
America's top hero Star and Stripe in My Hero Academia takes a massive satirical swipe at the US, as America's Number-One hero reveals her quirk. My Hero Academia has a history of taking shots at American culture, especially via previous top hero Playboy Hero: Captain Celebrity. However, while heroes of the past have often focused on relatively uncontroversial targets, Star and Stripe's quirk gets into much darker territory.
After receiving a plea for help from her "spiritual master" All Might, Star and Stripe quickly flies into Japanese airspace to face the villain All For One, and she finds him - in Tomura Shigaraki's body. A battle immediately ensues in chapter 330, where her terrifying and satirical quirk is revealed.
Called "New Order," Star and Stripe can impose new rules on reality, so long as she's touching the subject of her decree. She first imposes a new rule for the air directly around "Shigaraki" by making it not exist so he can't breathe. But since she can't set the rules of a second thing (other than herself) at the same time, a laser that "Shigaraki" fires in her direction forces Star and Stripe to drop her last order to make the laser safe to grab. The final rule she imposes is especially unsettling: "If Tomura Shigaraki moves at all, his heart will stop."
Of course, her opponent is able to move without his heart stopping, because Star and Stripe isn't really facing Shigaraki, but All For One. The only reason she successfully changed the rule for the air surrounding "Shigaraki" is because Star and Stripe didn't specify her opponent's name. She said, "As of now, the air does not exist 100 meters ahead of me." The fact that All For One was 100 meters ahead of her allowed the order to go into effect as intended.
My Hero Academia's New Order can easily be construed as a satirical swipe at America's treatment of other nations, as Star and Stripe swoops in without international approval and begins setting rules that disempower her opponent while empowering her. It's not an accident that mangaka Kohei Horikoshi chose to give America's top hero such an ability, but the name of Star and Stripe's quirk, "New Order," is particularly challenging. It evokes the New World Order conspiracy theory, which tells of a secret emerging totalitarian government that plans to dominate the globe, but is also a term used to refer to specific Nazi ideologies concerning conquered territory, drawing a particularly scathing comparison. Although Star and Stripe's presence brings hope to Japan in My Hero Academia, it also likely causes a faint unsettling feeling to wash over the country's inhabitants as they watch America's greatest hero arrive for combat, imposing rules on the air itself.
