Izuku Midoriya has the single most powerful device in existence and every single feature unlocked! Too bad he doesn't know it can transform him.
Master Control
is a My Hero Academia and Ben 10 Crossover Fic in which Professor Paradox gives Izuku Midoriya the Omnitrix.
Beware of Spoilers!
Master Control contains the following tropes...
- Arbitrary Skepticism: Inko resists believing Esta is a real alien or that the family visited a real alien planet. She prefers to think Esta is a cougar. Justified in that Quirks have made Earth life extremely diverse and the Omnitrix can use its internal Hammerspace to mimic other environments.
- Alternate Universe: The MHA and Ben 10 universes are alternate versions of each other.
- The Kraaho exist in both worlds with Ester having an older, full Kraaho counterpart in Esta.
- Anodites have a counterpart species in the Adronites. Adronites are blue compared to the pink/purple Anodites. They are notably vicious and are very similar to the Viltrumites.
- The unnamed Dragon who the Forever Knights captured has a counterpart appear in Izuku's world. He gets off Earth on the same day he crashes with Izuku's help.
- Probity has an older counterpart in Princess Provity, who ended the war her people were going through.
- Azimuth is the only one who explicitly exists in both universes instead of having a counterpart.
- Necrofriggians are explicitly nonexistent in the MHa universe.
- Contrasting Replacement Character: Ben, while heroic, uses the Omnitrix as a weapon to fight villains and takes a hands-on approach to heroics. Izuku acts as a Support Party Member who utilizes the Omnitrix's various functions to help bolster others, such as altering the DNA of others to give them better powers, creating items, or teleporting lost people back home and he defers to less violent methods even after learning to transform. This is emphasized when Izuku is teleported to Ben's world to stop the Highbreed: Ben was going to violently confront the high council, but Izuku, after meeting Reiny and hearing his story, suggests using Pesky Dust to share his memories with the council to convince them coexistence is possible (it should be noted that Ben did not have Pesky Dust by this point so it wasn't an option he had). Furthermore, Azimuth decides to let Izuku keep the original Omnitrix and gives Ben the ultimatrix, highlighting their different styles.
- Cuteness Proximity: Like in canon, the baby Necrofriggians are viewed as cute.
- Disappeared Dad: Hisashi is confirmed to have abandoned Izuku and Inko. This is a contributing factor to Izuku adopting five of the Necrofriggian babies.
- Expy: Itsuka's father is one to Nolan Grayson, aka Omni-man, as a Story-Breaker Power having father to a protagonist. He even has the same name.
- Good-Guy Bar: Cueball runs a biker diner as a side business. Per her specialization as head of the business course, it enables her and her employees to network, make new business deals, and gather information from patrons.
- Irony: Ben uses the Omnitrix mostly for straight forward hero vs. villain combat. It is given to Izuku, who, despite living in a world largely oriented around Hero vs Villain combat, focuses on very different functions of the Omnitrix.
- Point of Divergence: Because Izuku got the Alien Force era omnitrix, he does not have Whampire, who was scanned from the revived lord Transyl in Omniverse.
- Right for the Wrong Reasons: All Might, Sir Nighteye, Tsukauchi, and Nezu draw the correct conclusion that All For One is alive and active from the incorrect reasoning that Midoriya Izuku is somehow involved with him.
- Shout-Out: The person who steps in and stops Mirko from using Kirishima's internship as an interrogation over the Omnitrix is Agent Bubbles.
- Single Specimen Species: The Omnitrix creates a half-Anodite/half-human form after encountering Gwen, Verdona, Itsuka, and Nolan, the latter two being a counterpart species known as Adronites. Similarly to Nanomech, the form is a unique entity.
- World's Strongest Man: Itsuka's father Nolan is an Adronite and capable of destroying planets. He curb stomps All Might and it takes a One For All and Adronite-powered Itsuka and Izuku's new Adronite/Anodite/human hybrid form to defeat him.
