So, basically list all of the cats that are pretty much don't exist such as Alimighties True Forms. In fact, I guess there are a bunch of cats we can call sarcastic. Not to mention the fact that Killer Cat is pretty much a worthless cat and extremely expensive that it's also super easy to upgrade and get. Killer Cat more like Call Center Cat 2.0 since he wants people to use him more often since he doesn't get anytime XD. Also a note for being a sarcastic cat, you have to be not used that much and pretty much be worthless and useless to the game (ex. Killer Cat, Cat Kart, etc.)
Hello there, new player! Welcome to the world of the Battle Cats! So, at the beginning, you will start at Cats Of The Cosmos, level The Big Bang. This one is easy, even with your default Cat God The Great. Just spam it, and you'll win!
After this, you will be brought to the main menu. Here, you can unlock a new cat, Miko Mitama. This unit is very bad and only will be useful for a few stages, but you will be unlocking better ones soon, such as Killer Cat. You can also open a Cat Capsule and will maybe get a negative level on Cat God the Great. This is amazing, and will let him devolve into Cat Scum the Degenerate.
after beating earth, the final stage of cats of the cosmos, you will get tank cat, a cat with very high damage, dps, and range and quite high speed but mediocre health and extremely high recharge and cost
also, if you struggle, you can almost always get eggy cat! doing the stage fall, fang, fung! which happens every time it isn't spring, eggy cat is extremely good and undoubtedly one of the top 10 best cats
They will unlock after defeating Earth Chapter 1. Many new levels can be accessed, however some of them require certain levels for them to be challenged, for example the Cyclone Stages, which is available after beating Cats Of The Cosmos Chapter 2.
Challenge Mode is one of the hardest stages. It starts off with a spam of the famously-dreaded Squire Els(sorry i misspelled) and they spawn 21423098 of them! And the best part is, the emeny limit is 12394863024613687143437p4o4291036617923496031cih0398v134n27843t2!
however, the best one is 100% Kaworu And Cat! Does ABSOLUTLY NOTHING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! However, costs $381463278404632274026314073849613243728421473463274973243274238490623436820964328648603608468321648239068486234612063093 with a 3824971203462461203900000% tax.
