the very fact those with high and powerful imaginations are important for coming up with ideas although I'd use my own ideas I'm not very good at writing or certain aspects of writing such as the fact my problem with things such as adding periods to be honest its horrible but here we go

names are conventionally too similar and lack creativity in some so as an example here's simon snow sure its actually not too bad but its too similar you must help the name fit well it has to sound right rolling off the tongue or said out loud you could come up with many names if its a reincarnation or something such as demioch pronounced dem-ee-ock sorta like the angel och or a child of och demons elves many different names are said differently and pronounced different no matter how similar two may appear to look dreadnought Nosferatu demioch if you are a conqueror having a bad ass name is great or nick name or if your going for a comedy make it something hilarious and funny like a mighty gladiator or adventurer named pinky swish or him having some girls name like Emma Louise or risa or susu or something creativity is important in a story

worlds hmmmm that's difficult but there is hundreds of other planets in the universe and in anime and books do research investigate take inspiration for instance demioch could be reincarnated or transmigrated and given the appearance of a 6 foot tall guy with pale white skin pointy elf ears dragon slitted eyes and long shoulder length white hair with a muscular build but not too bulky not too lean somewhere in the middle with black daedric looking armor he seeks to adventure the many worlds and universes of the anime verse he is immortal has superior magical and physical capabilities on par with saitama of one punch man and magical capabilities on par with the wise mans grandson (can't remember the mc name sorry) he goes from world to world causing chaos or bringing order or both see? a story you can branch from and then start characters and more ideas such as the worlds populated with demihumans of all varieties and monsters and gods and goddesses you can come up with towns cities (please do a better job at it than our dear countries in this world sigh.... its a pain to have so many locations named the same thing don't you think?) so at this point you look for types of divinities and abilities powers and the such there's entire lists of names of angels and entire histories of gods and their divinities so can't be hard to find a name or dozens that you think fit a character and just if it doesn't completely fit change it up a bit nyx could be nexicon ,nyx,nyxana, or whatever you plant in there ? Apollo , Artemus, Zeus, Michael, Venus fera, zod, maximus, losran, leesrac, manstin, saki, diablo, demus, drachin, viperious, or ferianna all names come from a concept or word or letter but a mere thought can turn it into something bigger
