Sue originates from Cave Story. Sue is a short cute mimiga. She's very boastful, but she's all bark and no bite. She's got issues, and she takes them out by picking fights with pretty much everyone, despite being too small to hurt anyone.  She is quite rude at first, but after getting to know someone she softens up around them. The Doctor is trying to hunt her down and has sent Misery and Balrog to capture her. Sue was originally a human, but was turned into a mimiga by Misery.
