also make sure to include characterization! i want to see the character say things they would normally say in a way they would normally say it please! like mantis owuld be kind tone and not get fererences. Let them battle as themselves!
I would just like to say that i listen to your raps. also, this is not hateful, but a business advice. you are making raps that only appreal to guys who read comics in the 80s and 90s. if that is your niche and what you want to do, don;t listen to this. If you want a broader fan base, you need to appeal to them. I suggest doing some rap battles that more people can relate too.
mcu loki vs mcu thor vs mcu hela (battle of the triplet) (based on the avengers movies,not comics please)
also kpop is really popular so do a kpop rap battle like bts vs exo vs ikon or jungkook vs rm.
iruka vs kakashi would be good. perhaps with jiraiya so it would be battle of n arutos senseis
also please don't take the Lord's name in vain. Cuss less too please. Please make some kid friendly!
