story idea 1
overlord + marvel
give ache the toxin symbiote and see how that changes the story u can add symbiotes but if u give them to overlord peeps they already op i dont think the story would be to interesting to read if they are already super op giving it would be pointless as they would still be super loyal to aniz and nothing would really change in the story.
You need to give the symbiotes to new worlders that match like maybe climb with venom and carnage with clementine. aslo remember that the symbiotes can make all all skill and powers of there host better so this includes magic. the reason i chose ache is because she isn't used at all in very many fanfics and the ones she is in ether treat her like crap or where she is main focus only last for like 3 chapters sometimes even less.
story idea 2
spawn + anime
i just would love to see more spawn in different anime settings as there is not much fanfics of him. before u make a spawn fanfic keep in mine i want al simmons in a different universe not some random person that suddenly gains spawns powers...it just ant the same. here are some anime he could be cool in overlord, hunter x hunter, sailor moon, rezero, one piece. i know my hero academia has a spawn fanfic but i dont know if that fanfic is still going or not.
story idea 3
dangaronpa+x overs
i love to see some different peeps in this world and how might they change it.
like the hulk/ bruce banner how could him being there change the killing game or wolverine or spawn or iron man and other super peeps as i have looked and there is not very many storys with super peeps in dangaronpa that ACTUALLY change the story instead of nothing changing and them just being there.
pls let me know if u wish to use one of these ideas
