Kabuto Yakushi Vs Tomura Shigaraki

#### (Naruto Vs My Hero Academia)

* Orphans with messed up childhoods who killed their family member(s) [adoptive family member in Kabuto’s case], before being taken in by manipulative psychopaths (Orochimaru and All For One) who brainwashed them to be their tools and remember very little of their past
* These manipulative villains would also create a group of similarly brainwashed kids (the Sound Four and the League of Villains) and would entrust their students to act as the semi leaders and right-hand man to their masters. Eventually, these groups would take in an rogue brother (Sasuke and Toya), coming from an predominant family (the Uchiha and the Todoroki) with a proficiency in fire (Fire Release and Blueflame), who agreed to join the group in order to take revenge upon a family member (Itachi Uchiha Enji Todoroki).
* The villains who took them in would later battle an old enemy of theirs (Hiruzen Sarutobi/the Third Hokage and Toshinori Yagi/All Might) who they share a long history with (Sarutobi was Orochimaru's sensei while the original wielder of One for All was AFO's brother), a fight that would leave them in extremely delicate and fragile conditions (Sarutobi sealed the part of Orochimaru's soul within his arms and All Might critically injured All For One). Later on, these masterminds would be defeated again and locked way (Orochimaru was sealed away by Itachi's Susano'o and All For One was incarcerated into Tartarus) but not before their powers were giving to their apprentices (Shigaraki gains the All For One Quirk and Kabuto injects himself with Orochimaru's remains), which fused with their very bodies and gave them new appearances consisting of pale skin with grey hair and made them incredibly hard to kill, mostly due to their hyperspeed regeneration
* After gaining their powers, they started to gain an inferiority complex and recognized themselves as above their predecessors in every way, and only wanting to get more power as a result. They would also see themselves mirrored upon in an enemy (Naruto Uzumaki and Izuku Midoriya).
* For most of their lives, one of their main allies (Obito and Orobo) was originally a friend of one of the heroes (Kakashi and Aizawa), who studied with them, and gave their friends special eye related gifs (Obito gave Kakashi his Sharingan and Orobo gave Aizawa his goggles) before supposedly "dying" on a mission due to fallen debris. They would both later return as mysterious masked (Tobi and Kurogiri) with an ability to teleport as their main gimmick (Kamui and Warp Gate) after being found and influenced by a villain mastermind who was behind the scenes (Madara and All for One). During a conflict, these teleporting villains would re-encounter their childhood friend, who was now the teacher of a group of future heroes (Team 7 and Class 1-A) and using their eye related gifs in battle.
* They would eventually take over an big idealistic group (the Akatsuki and Paranormal Liberation Front/Meta Liberation Army) and used them to start a war (the Fourth Shinobi World War and the Paranormal Liberation War) due to their ideologies and distain for the world system (Kabuto felt betrayed by the Shinobi World for forcing him to give up so much that was dear to him and Shigaraki hates the current Hero society, considering it wrong and erroneous, because of his fathers abuse and his grandmother's abandonment which lead to that abuse). However, these wars also served the goal of capturing and stealing the power source of the main character which is sealed within them (the Nine Tails and One For All) and use it to gain a higher power.
* Their main numbers in this war came in the form of living experiments (Numos and the White Zetsu clones, funnily there's also a black vs white contrast here), thought to be created by one of the main villains (Madara and All for One)
