The Seraphim Unidentified Residual Energy Signature, nicknamed the Othuy, is a Seraphim unit. The Othuy is created when the Ythotha is destroyed. It is indestructible, and its Unstable Phason Laser fires quite rapidly for a high amount of damage. It drifts slowly, but does not move in one particular direction. When the Ythotha is destroyed in the water it causes the Othuy to lose its ability to attack units.
