Well, since copyright exist and you have no way of making your character use the ability, or idea. That have been shown in other people's works. Why not create a character of your own that has the ability to replicate the ability of every character in fiction. But, they are nerfed with a different names, and different incantations so it will not be labeled as copyright.
And transmigrated him in another world with this ability, not granted by any gods or goddesses or even a system and summoned as a hero. But his classmate who is secretly a high dimensional god who tried to experience a mortal life, and they became friends and was saddened by his death.
And because he helped this classmate of his getting bullied and became friends so inturn this classmate of his granted him such power. And when he got transmigrated he was alone in a vast grass field with trees far away from each other. And he did what all those who have travelled before time. He called out his golden finger, system, chat group, inventory, he tried every thing that came into his head even mommy.
Until he called out cute loli goddess, an array of magic circles suddenly appeared infront of his eyes and came out a fox eared loli in rage. As if she heard the title, she was given by someone. But when she appeared she was suprised that it was not the one that have constantly come to bully her. But a random mortal that she couldn't forsee its backround or even thier origin. So she followed him to know how this human know that person's way of calling her, but she was just dumb, stupid and foolish.
And instead of a demonlord that have tried to rule the world, the demonlord is not any demon or dragon or any western fantasy. But robot alien that crashlanded on this world thousand years ago. And the goddess should not be the conciousness of the world not its creator.
This world does not have a leveling system nor gifts or abilities that will be awakened. But they got throught books made by people of this world that have become stronger throught time. The hero is a reincarnator from a country called japan, but it turns out he came from this world first as the sage that discovered and created magic.
And now reincarnated as a hero, instead of defeating the demonlord as a hero with his party. He instead built mechas to fight the demon lord, because he thinks that fighting aliens with magic does not fit the whole thing as well as the setting of magic vs technology.
The elves are different as there are already many types of them in fiction so why not turn them into life sucking succubus, that captures any life and put them inside the world tree in order to survive and give birth to more elves.
The dwarves lived inside massive machines that roamed the land for centuries. Angels lived outside the continent right above the sea flocking like birds as a floating city is just right above them. Below them and every part of the ocean mermaids and sea beasts lived but they eat any living being on this planet besides their race.
The dragons are not wyverns since alot of them are wyverns and are still called dragons and feared in isekai japanese novels. But instead of their scaly body they are instead differentiate like they were failed experiments created from a lab. Since they looked like a mixture of many creatures that lived on land aswell as the skies since there are floating islands in the sky, but some are scaly like the dragon you see on western fantasy. Since they wouldn't think about low dimensional game and shepherding humanity.
The strongest spell made by one of the strongest of the world is a cleaning spell used to clean the concept of dirtyness of a house.
Guards at the gate walls aren't armed with swords and spears instead they were bows.
The great inventor does not invent something good that can help the progress of technologies. But, became one after inventing a tool that allows him to invent new drugs, that allows him to see. The secret color and many wondrous things in the world. Even rainbows all around him, but he was soon fired by the king and was broken as he didn't invent or create something that can help them. Because he just invented drugs to see his wife that he created in his mind.
The churches does not have corruption in many branches in the world. The goddess didn't respond them back, because she became addicted to games in the computer she had created after instantly knowing from the hero's knowledge because of her omniscience of this world. But that only applied to residents of this world so the hero reincarnating counts.
the nobles still has corruption, and the king is a shota and the duke a beautiful lady usurped the power of the king in secret and they later got married.
