I asked to rank all the purchasable special cats (find all of the actual special cats and count how many there are!)

Also ninja cat is said twice but count it once

Here's a ranking of purchasable special cats in Battle Cats, considering their overall usefulness and impact on gameplay:

Tier S (Top Tier):

• Ninja Cat: A versatile unit that excels in both offense and defense.

• Crazed Tank: A powerful tank that can absorb a lot of damage.

• Miku Mitama: A fast attacker with a high attack rate and the ability to curse enemies.

• Kasli the Bane: A versatile unit that can deal extra damage to specific enemy types and weaken them.

Tier A (Very Good):

• Rocker Cat: A strong attacker with a wide attack range and the ability to weaken enemies.

• Manic Eraser Cat: A powerful eraser cat with increased stats and abilities.

• Cat Machine: A tanky unit with a powerful attack and a chance to stun enemies.

• Courier Cat: A valuable support unit that can increase the attack speed of other cats.

Tier B (Good):

• Eraser Cat: A basic but effective eraser cat.

• Ninja Cat: A good early-game attacker.

• Sumo Cat: A tanky unit with knockback immunity.

• Skirt Cat: A useful unit for breaking barriers.

Tier C (Situational):

• Zombie Cat: A combo-based unit that can be useful in specific situations.

• Mr. Cat: Another combo-based unit that can be useful in specific situations.

• Kung Fu Cat: A mid-range attacker with wave immunity.

• Cats in a Box: A rush unit that can be useful for overwhelming enemies.

Tier D (Not Recommended):

• Bondage Cat: A weak unit with limited usefulness.

• Panties Cat: A weak unit with limited usefulness.

• Actress Cat: A weak unit with limited usefulness.

• Dom Cat: A weak unit with limited usefulness.

• Samurai Cat: A weak unit with limited usefulness.

Remember that this is just a general ranking, and the best cat for a specific situation may vary. It's always a good idea to experiment with different units and strategies to find what works best for you.
