Return Of A King - Redux Provides Examples of''
- Adaptational Villainy: Unlike Canon, Izuku Midoriya is not the successor to All Might, but rather the reincarnation of The Demon King Kibutsuji Muzan. This can also be applied to the likes of Ochako Uraraka, who Izuku turns into a Demon in Vol 2 - 3: Revelations - Part 3, and as of Vol 3 - 8: The Price Of Peace - part 5, Eri becomes a Demon as well. In Vol 4 - 1: Creating The Moons - Part 1, Fuyumi Todoroki and Kota Izumi are also turned into Demons.
- Adaptational Badass: In canon, Eri is just a small harmless child with an overpowered Quirk. In ROTK - Redux, Eri is a Demon with a powerful Blood Demon Art and a craving for human flesh.
- Adorable Evil Minions: This applies to both Eri and Natsumi, both of whom are little kids. Despite their appearance, they are just as dangerous as their cohorts, which they use to their advantage.
- Affably Evil: Despite being a villain, much like his canon counterpart, Izuku is quite nice to those whom he deems his allies and friends.
- Anti-Villain: Instead of being the typical Hero, due to the path he has walked down, Izuku ends up becoming a villain. Though, he becomes a villain with the goal of who wants world peace.
- The Big Bad: Seeing as Izuku is the main character, his journey is about him becoming the most powerful Villain in history.
- Big Bad Duumvirate: Both Izuku and All For One end up having to work together, mostly because Izuku is being Blackmailed by the latter.
- Big Bad Wannabe: The leader of The Shie Hassaikai Kai Chisaki is this, as in his major appearance, Izuku takes him out in one shot
- Create Your Own Villain: Due to the actions of the society that Izuku lives in, his descent into madness was the fault of everyone around him. At least, he thinks so anyway.
- Curb-Stomp Battle: Most fights that Izuku gets into tend to be this, as no one has the combined strength of might to take him on and win. For example, his battle with Yushiro ends after Izuku blindsides him with a wave of flames he creates using his Biokinsis Blood Demon Art, then cutting his head off with Yushiro's own Nichirin Blade.
- Devil in Plain Sight: Everyone Izuku meets thinks him to be an upstanding guy when in reality he's actually a villain, and one of the most notorious ones in all of Japan.
- Driven to Villainy: Much like in canon Izuku doesn't exactly live the best life, being bullied at school for his creepy eyes (though he doesn't really care) and after losing his friend in something that could've been prevented, to say that Izuku is discontent with society is an understatement. But it comes to a boiling point when Izuku's Demonic Blood finally kicks in and he eats his mother on complete accident that he becomes who he is now.
- Even Evil Has Loved Ones: Despite being the reincarnation of Kibutsuji Muzan, Izuku, while he may not show it outwardly, cares for the Demons he creates as if they were family. He gets really pissed off when one of them dies, namely Ito, who was the first person he turned into a Demon.
- Even Evil Has Standards: Despite being a man-eating Demon, Izuku draws the line at killing or hurting little children or innocent people, and he enforces this upon the Demons he creates.
- Fedora of Asskicking: In most of the fights that Izuku gets into, he's always seen wearing his Fedora, though most of the time when the fight gets serious his Fedora flies off and he reclaims it later.
- Femme Fatale: Most of the Demons that Izuku has created just so happen to be women, and it is not on purpose.
- Not So Invincible After All: Izuku finds this out when he gets attacked by Yushiro using a Nichirin Blade. The first weakness he's ever encountered regarding himself.
- No-Sell: When Izuku encounters Kai Chisaki, he completely obliterates the man with a single attack. Despite the story building up Kai Chisaki in such a way to make him an extremely deadly foe, him going down in one go goes to show just how powerful Izuku really is in this fic.
- Red Baron: To the world, Izuku Midoriya is known as The Hero Cannibal, for very obvious reasons.
- Took a Level in Badass: Kyoka Jirou, being the descendant of Tengen Uzui, has learned how to use Sound Breathing in tandem with her Quirk Earphone Jacks, making her far more powerful than she was in the canon.
