Oodle is an interdimensional demigod-like being with a white equilateral triangle body, a jade-colored outline, and limbs. He has a very cheerful, optimistic, and kind personality, treating people he meets for the first time as friends rather than mere strangers and prioritizing their happiness. He appears to have suffered from long-term loneliness in the past, which leads him to make jokes or sometimes go to extremes to get close to others. While he values friendship and manners, he is sometimes naive and shy, often failing to realize that his actions might make others uncomfortable. He is usually patient, but if pushed past his limits, he can become irritable or aggressive. As much as he pours affection into those he considers special, his obsession grows just as deep, often causing trouble for those around him. Although he possesses various professional skills and talents, he has weaknesses in academic areas and collects souvenirs obtained from traveling through multiple dimensions. Furthermore, he wants to give everything to the person he likes by using his powerful abilities such as reality warping, object creation, dimensional travel, and shapeshifting.
