Son Goku, The Fight against the Ultimate Evil
This is part of my main timeline, in which at age 18, Goku met Usagi Tsukino, known as Sailor Moon, when she was 17 years old, thus making them currently 44 (Goku) and 43 years old (Usagi).

I own nothing, the characters excepting Lucifer's forces are property of their respective owners (Akira Toriyama, Naoko Takeuchi, Masashi Kishimoto, Toei Animation, etc.), all while Lucifer's forces, especially Lucifer himself, seem to be public domain characters, I'm not very sure though. As for the places, I own none, e.g., Namek, Yardrat (Akira Toriyama), Katina, Corneria, Venom (Star Fox), all I own is the story, and even then, it has inspirations of other works.
Chapter 1: The Beginning of the Devil's Rule
A peaceful day, at the meadows of Mount Paozu, Yamcha was relaxing, slouching on a nearby tree, until a dark cloud of black anti-matter flew over to him. Once it got near to the desert bandit, it spawned a bunch of long, creepy arms that tried to grab anything nearby.
Yamcha: What? What is that thing? (Shudders and shakes) Hmm, one thing to do now. Wolf… Fang… Fist!
Yamcha threw himself to the dark cloud, trying to hit it, but was grabbed by demonic force chains.
Yamcha: Agh, ghh, grrgh, I… can't get… out…
Yamcha blasted part of that dark cloud with a Kamehameha, getting out of its grasp.
Yamcha: I've gotta tell Goku and company about this! It's an emergency. (Runs to Goku's house, but doesn't find anyone) Argh! They're not here! I must tell them or else they'll have a sudden defeat! They must be at Capsule Corp.!
After saying this, Yamcha fled as fast as he could to West City, specifically to Capsule Corp, where Bulma's house was located. The desert bandit found Ten Shin Han, Chiaotzu and Master Roshi. Desperate, he decided to tell them what he saw.
Yamcha: Guys! Bad news coming! You must listen to me!
Ten Shin Han: What would it be? I recently had a bad feeling about something…
Yamcha: Well, results that while I was relaxing at Mount Paozu, suddenly a black blob appeared and then threw a bunch of arms that tried to grab me.
Chiaotzu: What did you do then, did you use a Kamehameha or a Wolf Fang Fist?
Yamcha: I used the latter, but some kind of chains trapped me, and I had to use a Kamehameha to get free. It looked like a demonic force.
Master Roshi: Holy moly! Demons are invading this planet, and if nothing is done, we'll be dead in no time. It's time to gather the team!
And so, the three warriors and their master looked for everyone that could join them, from the mighty Goku, Vegeta, the 10 Sailor Scouts, Jiren and Arale, to less useful fighters such as the farmer Nofu. Everyone went to Capsule Corp, where they were told the whole story.
Bulma: So, why are we here reunited?
Yamcha: When I was at Mount Paozu, relaxing under a tree, once I got up, a blob of darkness flew over me, and threw arms that would grab anything, I tried to attack the blob, but it chained me until I used a Kamehameha to destroy part of it.
Ten Shin Han: The most acceptable theory is that said blob must have been a ghostly or demonic force.
Goku: Wait, you're telling me a demon is coming? This is both good and bad, good in the way I'll meet a strong opponent, but bad because that demon could have a deadly goal and might succeed at it if nothing is done.
Vegeta: I almost thought you'd commit the same thing as in the Tournament of Power, but you're right.
Sailor Moon: Then what are we waiting for? Let's go!
Sailor Mars: But first, who or what is behind this strange paranormal activity? I recently had a vision of Vegeta-kun dying at the big foot of a big, red dragon with bat wings on it.
Suddenly, rust-colored mist surrounded our heroes, confusing them.
Krillin: W-wh-what's going on here? This must be a demon causing all this, right?
And then, a sinister voice was heard.
?: No longer a demon, but the god of all cosmos!
Goku: Who is it? Reveal yourself!
?: I am the most high, the greatest one of all, my name makes people feel happy, I am Lucifer the god of all worlds and dimensions, when the brightest heaven is conquered, I will finally bring joy to everyone!
Piccolo: Did you cause all this? If so, your days shall be numbered!
Lucifer: I cannot be defeated, for I am soon going to be god! All these clouds of darkness and all that mist is a manifestation of my exceptional power!
Gohan: Guys, look! The sky is darkening!
The sky of planet Earth was darkened into a shadowy magenta color with pale greenish grey hues, and some of the vegetation was turned into ashes or dead grass.
Lucifer: See? I have already conquered Earth, all that remains is to reach the highest and brightest of heavens, enter the gods' palace, obtain the crown for the greater good of all the cosmos, and finally rule everything like it should have been done eternities of eons ago!
Goten & Trunks: You won't succeed, you're too inept for that anyway!
Lucifer: SHUT UP YOU LITTLE BRATS! (Regains his demure appearance) In any way, if thou want to stop me, I'll only give thee 6 weeks, 6 days, 6 hours, 6 minutes and 6 seconds counting from the next 3 seconds, but don't think I will go easy on any of thee. (A deluded laugh is heard)
Bardock: Only 48 days and a quarter with 6:06 additional minutes are left from now on, we need a spaceship for this mission!
Gine: But how are we supposed to travel the cosmos in only that time?
Bulma: Don't worry miss Gine, I can build a giant spaceship in only 30 seconds, using other models!
King Vegeta: This is excellent, with this, that idiot of Lucifer will be taught his place.
Grandpa Gohan: I know we will defeat that villain, specially having Goku at our side, with him and Usagi, nothing is impossible.
Master Roshi: I just hope I have as a reward for defeating Lucifer a pair of…
Android N°18: You were going to say ''a pair of dirty magazines'', weren't you master?
Umigame: Master, you really should control your perversion, in any way, we must get going.
Nofu: I know this will be intense, that's for sure.
That would be it for chapter 1, and by the way, Nofu is the Japanese name for the farmer with shotgun, and Umigame is the name for the sea turtle of Master Roshi. How will Lucifer rule the cosmos? Is he going even more insane than before? How will our heroes travel to the cosmos? Find out on the next chapter of this series!
