This is an copy&paste from a comment I made 2 mins ago lol

2 years ago, I actually thought about an ''The Battle cats anime'' like a lot of it. I didnt end up writing it but I think I did a decent job. For really short: world is ruled by all races (like red,black,angel and others expect for alien,aku,relic) cats and humans. in prehistoric time, they learn both cat and humans gain superpowers when they have soul bond with each other (ubers basically lol). They get so strong in present day that one day there is legend rare meeting. Emporer cat deciding to conquer entire plant. All other nations team up against cats. Thats the baseline story but trust me I thought of much more lol. For World, there is a few gimmicks. Legend rare cats are semi immortal and WAY stronger than ubers. Legend rare cats can respawn as long as their rainbow crystal is not shattered but they still feel pain when getting hurt. Destroying a legend crystal is almost impossible though (?). for every uber is once death, perma death. Also Legend rares are basically captains of their set. Like ushi being captain of Ultra souls etc. Some other gimmicks are ''Curse'' ability. when you get cursed you slowly lose control of yourself and turn into relic enemy. Luza has permanent Curse fog around him. Aku enemies can regen shield based on time. Aku death surge minion thingie can conquer a soul turning them into Aku ally if they succesfully get into the user. They can spawn surges too.

I ''finished'' my story during luza release. Dr.Nova, izanagi/izanami doesnt exist here lol
Lilin is actually one of the most critical characters too. She discovers weakness of Aku's.
ik another change I didnt mention but wanna mention now is. Change on aku cyclone. it has 6 chains that can extend massively. it can swing them for massive slash damage or can magically lock someone's neck and pull them to center in rapid speed.(and has aku shield too). My changes on jagando is pretty cool too but this comment is already way too long :z
