Bubble, being a creation of Caine, is just as chaotic in nature as he. He is rather destructive, unhinged, and obnoxious ar times. Some of the things he does, such as licking Pomni's vomit off of the floor to clean it, even freaks out Caine. Sometimes quiet and acts like a pet that doesn’t understand anything but he actually does but mostly keeps quiet and he’s annoying. Also he’s a menace and will eat your food. And also goofy. He’s physical form is just a Bubble with  black eyes and sharpteeth
