Gradient is an ambivert. When he’s around new people, he'll close up and become shy and awkward at first. He’s an intelligent person with a passion for discovering new things. Whenever he becomes flustered, his form will start to bubble (like a lava lamp) as his body starts to change from a solid to a liquid. He's a perfectionist, which means everything he makes is never "good enough for him." His fathers are Ink and Error Sans, and he has a younger brother named Paperjam (or PJ) who annoys him.
