Nightmare Fuel / My Hero Academia: World Heroes' Mission

• The Humarise group, guided by the Quirk Singularity Theory, believe that all people with a Quirk are tainted and declare their intention to purge them all with the help of the Trigger Bombs.
• The opening scene, which features Flect’s first demonstration of his chemical weapon, the Trigger Bomb, which pulls no punches. The viewers get to see the full effects of the first Bomb. Flect Turn activates it in a random city to demonstrate Humarise's power and goal to "save humanity". Countless civilians die Cruel And Unusual Deaths as their Quirks go wildly out of control. In the end, we are left with scenes of streets littered with dead bodies, while much of the city is in flames.
  • Only the Quirkless people survive (though there is the implication that several of them also died during the event indirectly).
• Before Midoriya, Bakugo, and Todoroki head to Humarise's headquarters, Midoriya has an Imagine Spot where he sees all of the Pro Heroes he knows and his classmates' dead bodies in a pile with Flect Turn standing triumphantly on top of them. This is when the three realized that Humarise led all of the world's Pro Hero population into a giant trap, and it nearly WORKED.
• The bombs are revealed to have been planted in 25 countries around the entire world.
• In the third act of the movie, even as Midoriya, Bakugo and Todoroki refuse to give up, the strongest members of Humarise give the three heroes-in training the hardest fights out of the three movies:
  • Deku's initial Smashes against Flect Turn critically wounding his arms and legs since the latter's Quirk allows him to reflect everything.
  • The Trigger-enhanced Serpenter twins nearly succeeding in killing Bakugo via Death by a Thousand Cuts several times during their battle.
  • Todoroki nearly drowning when a similarly Trigger-enhanced Leviathan takes the battle into an underwater passageway and repeatedly restrains him with twister-tentacles.
