Separate from the main timeline, let's take a look at potential paths that Goku, Makima, and the rest could've ended up taking on. Along with the threats that appear to destroy their world. (The Z-Movies)

Y si personas totalmente opuestas se conocieran, es una receta para el caos, ¿No? Pero, ¿Y si hablamos de un diablo controlador y un adicto a las batallas? Solo Dios sabrá lo que aquella unión traerá al mundo. Para bien, o para mal.

有一个人叫denji。他不只到他在哪儿

The Control Devil and the Saiyan raised on Earth, an unlikely pairing inside of a world shrouded in chaos and wackiness. And the only way to make it work is to get through it together, dragging everyone else along for the crazy ride! Here are their adventures! (Previously titled 'A Devil's Darling')

Denji is a very poor kid from the country who was going to die because his parent left him nothing but debt. However, he meets a weird dog which he names Pochita, and together they do all sorts of jobs. As time goes by he discovers about the existence of Devils among people and a mysterious girl named Makima tell Denji to enroll UA to help kill all the higher-up devils out there.

Issei Hhyodou is a pervert who wishes to have a harem, Denji is a poor kid who has nobody in the world outside of a little dog with a chainsaw. Issei becomes a reincarnated Devil and Denji becomes a devil hybrid thanks to his dog. Now with their new powers, both will fight for what they want thanks to the help of a woman of beautiful red hair and yellow eyes. Also, Rias is there.

Denji was sleeping on on to very normal night with a not very normal outcome.

The Dimension Devil transports Denji to the Jujutsu Kaisen universe, where Denji's devil nature gets him mistaken as a curse. The Chainsaw Curse's immediate execution is hereby declared by the higher-ups, until Gojo Satoru decides to intervene... As far as Denji is concerned: Curses, Devils. Kill them, for food. Be good, for Yuji. Same shit, different day. Yuji/Denji

Un esqueleto mágico llega a un mundo de demonios

CSM MANGA SPOILERS - In all of Makima's wisdom, why wouldn't there be a failsafe intact? Or in other words, a hero of Hell arrives in a world of heroes.

Izuku Midoriy was not having a good day, first the teacher had told the class that he was applying to go to U.A. Then after Kacchan had burned his notebook and now there's a sewer monster trying to enter his mouth and take over his body. This is the story of Izuku finding that he can summons Devils, what will he do to reach his dream to be a Hero "What was your name again Mis?...F"

The Multiverse has many possibilities. The Control Devil was reborn in the body of a person who became a Neet because of others wanting him to be like his father, but now that Subaru Natsuki has incredible power. He realizes he could be greater than his father by creating a better world than the one he lived in but now he shall rebuild the world of Lugunica in his image.

Sasuke was a little smarter in how he decided to cut Naruto out of his life, by playing on the fact he is a hero.

In A World Of Devils, Vampires And Chainsaws (I Own Nothing)

Those who control information control power, and those who control power control the destiny of humanity.

Makima found herself in a strange world after receiving the highest honor of being consumed by the Chainsaw Man. It was certainly a fascinating place that didn't contain Devils, Devil Hunters, or Fiends. Can this world change a twisted influence like her? Can it be untwined into something extraordinarily beautiful, or will she remain forever as she is?

Waking up to a world where seeing the next day is entirely up to fate and luck isn't what I had in mind for an Isekai much less waking up as a Vasto Lorde.

A Human Son, A Jujutsu Dad, And A Devilish Mother (CSM X JUJU KAI X Demon School Iruma) (I Own Nothing)

It was a chance encounter. Despite what some may say, Makima never meant to meet him. Such was never her intent. Had she been made aware of his silver tongue prior, she would've run. But she didn't. Hindsight is as they say, twenty-twenty. Looking back, she underestimated him. More fool she-their world will never be the same. NarutoxMakima? Narutoxharem? Inspired by Death Battle!
