Fanfic / BNHA: the Thunder Rolls

Go To

BNHA: the Thunder Rolls is a crossover between My Hero Academia and Shazam!, where an aged Billy Batson poaches Izuku from All Might, causing the boy to become the heir to the power of Shazam instead of One For All.


  • Bait-and-Switch Comment: When Momo is ready to beat the crap out of Shigaraki with a metal bat, Kirishima tells her not to do it - unless she is going to share with the rest of the class.

  • Destructive Savior: A number of the injuries Izuku treated in his fellow test-takers were caused by him, like flaming debris from a three-pointer.
  • Does Not Know His Own Strength: In spite of Billy showing Izuku the ropes of his new powers, Izuku is still working out the kinks of actually gauging the appropriate level of force to use. On multiple occasions during the entrance exam, he had had to rescue someone from one of his own blunders, like from the flaming debris of a three-pointer that he hit hard enough to explode, and his attempt to fend off the zero-pointer when it threatens Uraraka ends up demolishing it completely, causing him to freak out and worry that he's going to be billed for it.
  • For Want of a Nail: Thanks to Billy's arrival in the MHA universe, Izuku ends up inheriting the power of Shazam rather than One For All.

  • Forced into Evil: The Noumu, who turns out to be a child who was experimented on and forcibly given several Quirks, and even then the only way it would act violently was by forcing a face control harness.
  • The Friend Nobody Likes: The heroes on UA's staff don't have a high opinion of Endeavor, let's just say that.
  • Heel–Face Turn: When Izuku tears off Noumu's face harness, he becomes docile and stops fighting.
  • Helping Would Be Killstealing: A few people Izuku saves during the test get mad at him for stealing their Villain points, though to be fair he wasn't trying to destroy the robots most of the time.
  • How Do I Shot Web?: Averted, when Billy grants Izuku the powers of Shazam, he does what he says his mentor should have done and gives him the rundown on his new abilities.
  • The Klutz: Part of the reason Izuku has some trouble with his powers is that his Shazam form's size throws him off, he transforms back when trying to get Uraraka's boot off, for example, because his "man hands" are making it difficult. Nedzu even directly refers to him as a klutz.

  • The Multiverse: The worlds of My Hero Academia, D.C, and Marvel at least are canon to this work.
  • Obvious Rule Patch: Uraraka destroys the mock bomb when it becomes clear that she and Izuku can't capture it, but in the hopes that All Might will accept it in the name of "Broken Arrow". All Might gives them half-credit but declares doing so in the future a no-go.
  • Passing the Torch: The core concept of the story is Billy Batson passing on his powers and hero role to Izuku.
  • Secret Secret-Keeper: Billy seems to be aware of All Might's condition and other issues, when he's complimenting Izuku for showing more compassion, patience, courage and competence under fire than the last ten Pro Heroes he'd seen that week combined, his smile gets a bit sad when Izuku asks if that includes All Might, and says that he gets a pass.
  • Secret Test of Character: Billy, pretending to be an ordinary old man, lets the Sludge Villain attack him to see what Izuku will do.
  • Superpower Lottery: Izuku having the power of Shazam wins it, hands down. He can even tap into his abilities in a more limited capacity without transforming, unlike Billy.
  • Surprisingly Realistic Outcome:
    • Izuku can electrocute people with his transforming bolts if he's not careful, though he's careful enough to know the exact safe distance, and transforming indoors causes damage to the roof. Lightning is also hard to aim.
    • Billy made a good decision telling Izuku what his powers were, but Izuku still has some trouble with gauging the level of strength to use due to lack of experience, especially because his Shazam form is a lot bulkier than his normal scrawny self.
    • The powers that be don't want to look too closely at anomalous Quirks, bureaucrats wanting to keep things in their neat little boxes and scientists who have no more idea about how Quirks work and are passed than the average person does, despite what said average person thinks, want to avoid more things about Quirks that fly in the face of science and genetic knowledge.
    • Nuclear weapons are actually surprisingly fragile things, and while they can explode if deliberately damaged, it doesn't trigger the nuclear reaction so the damage is far less overall. Uraraka purposefully destroys the mock bomb during the Hero vs. Villains exercise when it becomes clear that they can't capture it for precisely this reason, hoping that All Might would accept the result.
    • Even after his age is revealed, Noumu has to go to Tartarus Prison simply because no other facilities can handle someone that powerful.

  • Take That!: Billy does not have the best opinion of Carol Danvers.
