Chapter 1: Jack spicer Diamond Master
Chapter Text
This is an idea that newgodnika2099 suggested to me in the comments of chapter 15 of the story of Jack the Serpent King.
The premise would be that instead of Jack's parents sending him the box where Wuya is imprisoned, they would send him a diamond with an image of a dragon, along with what appear to be other embedded gems. This diamond would bond with Jack, making him the Diamond Knight Master, granting him magical armor and crystal magic (although he won't be very powerful at first; his power will grow as the story progresses). Jack's gem would also serve as a compass to search for the Crystal Beast gems so that together they could summon the Rainbow Dragon and seize its power.
The crystal gems will already be linked to users; the list would be:
Ruby Rose - Ruby
Chloe Bourgeois - Topaz
Charmcaster - Amethyst
Hunter - Cobalt
Gus Grav - Amber
Aelita - Sapphire
Danielle Phantom - Emerald
I also thought about some rivals for Jack in the quest for the rainbow dragon, as well as in world domination:
Zero - from the Pokémon movie Giratina (especially because I liked how he used the Magnemites as minions, just like Jack uses his Jackbots, and I thought it would be an interesting fight between them)
Ryuga - from Beyblade (only the dragon emperor can use the power of a dragon)
And for now, that's all I can think of for this idea. Leave in the comments what you think and any other ideas you have, and I'll see if I do it. I also accept help writing other ideas.
And for those wondering... The story of King Serpentine will still be the main one I write (I've already dedicated a lot of effort to it), and I'm already starting the next chapter, so don't despair. This is a side project and a way to give me ideas that I could include in the story or to create others.
Chapter 2: avenger isekai
Chapter Text
Here's a new idea for a story I've actually wanted to do for a long time, but I haven't been very good at setting the scene and pacing it. But here's the general idea:
A soul dies and reincarnates as the Avenger Angra Mainyu from the Fate series in Shiro's body (in his second Ascension, for those who play Fate: Grand Order). At first, he'll be stronger than the average human but weak in the magical/supernatural world (as he's "the" weakest Servant, something he proudly boasts about). Of course, this won't last long, since thanks to a "small" push given by the being who sent him to his new life as well as to his meta-knowledge, he'll find ways to become stronger and use his imagination to adapt his powers to strengthen himself (after all, he's "all the evils of the world"—that has to give him something). He'll also have a personal Fate-style stat sheet to help him measure his progress in terms of power and status, and here's an initial one for him.
Angra Mainyu
Alias: All the Evils of the World/ Ahriman of Sin
Type: Servant, Human, Daemon
Gender: Male
Height: 167cm
Weight: 58kg
Element: Void
Origin: Sword/evil of humanity
Source: Zoroastrianism
Region: Ancient Persia
Alignment: Chaotic neutral
Class: Avenger/ beast VI/R
Parameters
Strength: E
Endurance: E
Agility: A
Mana: D - A
Luck: E+
NP: D→EX
Class Abilities
Avenger: A
Correction of Oblivion: A
Independent Manifestation: A
Crown of the Beast: B
Personal Abilities
Wish for Annihilation: A
Sin of Humanity: EX
King of the Daemons: B
Noble Phantasm
Verg Avesta (Anti-Unit): D→C-
Tawrich and Zarich (Anti-Unit): C
Azi Dahaka (Anti-Army/World): EX
As you can see on the character sheet, he will have the Beast class in addition to his normal class, and thanks to that, he will have new abilities and Noble Phantasms that will make him a powerhouse in the world he goes to. Speaking of the world he goes to, it will be a crossover world of Justice League Unlimited, Teen Titans, Miraculous, Jackie Chan Adventures, Xiaolin Showdown, Danny Phantom, Witch, RWBY, Winx, and maybe I'll add others if I decide to write the story, since, as I said, I've wanted to write it for a while, but I don't like how I'm developing it, and at the same time, I get writer's block. But getting back to the character, in addition to the other abilities shown on the character sheet, he will also be able to summon his cursed mud, which will allow him to corrupt people, as well as summon and control his Daemons in the style of Grims from RWBY (hence his ability, King of Daemons).
That's all for now regarding that idea. If anyone is interested in helping me write it or wants to take it up and write it themselves, let me know in the comments. See you in the next chapter of King Serpentine, which is still to be written, so don't despair!
