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.)

Snivel is very accident prone; it hurts itself on a regular basis from being clumsy. It really doesn’t approve of or like fighting and wishes its species was more peaceful. Its main reason for choosing a medical path was that it was the least offensive towards injuring people. Unfortunately its clumsiness makes it rather difficult for the instructors to take its wishes seriously. Ultimately it wants to venture into developing medicine and pharmaceutical tasks. Whether or not they will actually let it is unknown. In the meantime, Snivel does the best it can to help the unofficial crew—which isn’t much. It knows how to use bandages and anti-infection ointments—but that’s about it.
