Flame Knight Cat
This towering knight in a green tunic wields a cape and a massive flaming sword. It also requires you to already have the Knight Cat which can be purchased from the Collection Cat which can be purchased for 3000 gold.
Playing as Knight Cat on the Fantasy stage you want to find the red fireball obstacles and just jump on in. Die via fireball five times and you'll unlock the Flame Knight. Sometimes touching the stove makes you learn that the stove's hot and sometimes it teaches you that if you do it enough times you'll acquire a demonic hell blade. Live and learn.
Ice Queen Cat
Remember when I told you that burning your knight can get you the flame knight? It was literally two paragraphs up. Well guess what you get if you bring the princess around ice? Yup, for this one we're going to need the Fantasy stage.
Playing as the Princess Cat, who costs 3000 gold, you're gonna want to head over to the Fantasy Stage. After around 350m you're going to find blue ice balls instead of fireballs at times. If you can jump past 10 of those with the Princess you'll unlock the Ice Queen. This doesn't have to be in the same game so don't worry if you lose and start over, you just need to get past 10 even if it is only once per game.
This one is so easy to unlock I was legit upset when I realized. Especially as I like the ones that look like they have superpowers. Psionic Cat is a superhero that looks kinda like a Mega Man boss surrounded by orbs of electricity and is just stupid easy to get.
Head over to the fantasy background and play until you find the yellow electricity orb. Slam into it and then revive. Donezo.
Lancer Cat absolutely surprised me when I unlocked him. It looks like a big armored enemy from out of a Mega Man game. It has almost a completely different art style from what you're used to and it's third jump features a massive animation of it attacking with a lance. It's huge and menacing which is exactly what you want in your adorable kitty game.
To get this hulking boi, you're going to need to hang out in Dungeon mode. While attacking enemies make sure you're hitting the projectiles with your sword as well. Once you destroy 300 projectiles in Dungeon Mode you'll unlock the Lancer Cat. Don't worry, it can be done over a multitude of games, not all in one unlike the Reaper Cat we'll get to later.
On the next page we'll get into the Mad Scientist, Frankenstein, Count Dracula, and Van Helsing Cats. See you there.
