The Od are foxes, creatures that hunt and chase. They are the blood that brings all Shells to life, bringing forth their freewill, capacity for both violence and kindness. One of Od's halves is always smaller than the other, delicate alongside its larger and more vicious looking half.

Those who possess the Spirit Type of Od have control over sound waves. Those that have this spirit type will have the ability to create shockwaves and temporarily stun others with loud blasts of noise. The proficient will be able to increase the gravitational force in their immediate surroundings, as well as sensing vibrations through the earth. The Od are most powerful when angry, and the more powerful that they become, the more susceptible they are to having violent outbursts. They will be prone to berserker rages and blind fits of impulsivity, and may not take well to being given orders. At the height of their skills they are able to create earthquakes or crush other creatures alive. Over time, the Od’s bone density increases, making them slower, heavier and more liable to dislocation.
