These guys are super super super minor characters but I've given them refs anyway. The particular set this kitten is from are yet to have graduated from the academy. That means they're not actual invaders.
Also kittens are usually very excited to choose their invader names and have them long before they've actually graduated--so that's why it has one if anyone was curious. Also no official names will be listed because since they are such minor characters, it would be a pointless detail to spend my time researching until I found one I liked. (Because I wouldn't settle for what came to mind first.)

Keylime Slime is very passionate about becoming the best fighter it can be. A resilient little cat that is surprisingly very teachable, responding with eager intensity. Keylime Slime looks up to Spork—a Qwuedeviv it has heard excels in hand to hand combat—and of course every kitten wants to envision themselves as the next big, bad invader. It happens to be one of Spork’s biggest fans back on Qwuh-9 and its number one dream is to meet Spork personally—some would discourage such a goal, but this kitten seems to have its mind made up. Despite its usual tough and sometimes arrogant look, Slime is actually quite caring about its friends and others. It will do its best to defend them if needed even at the expense of its own safety. The Qwuedeviv kitten tends to use up all its energy to the point it will fall asleep in random places.
