The Spirit of the Magic Mirror is not inherently evil, rather it is an obedient servant who will do whatever it is told. It is shown to have little to no emotion, which is emphasized by the dull, monotonous tone in his voice.

Despite its loyalty to the Queen, it has refused her orders, an example being when it was ordered to destroy Terra. It refused, stating it could only answer questions, though it was later forced into doing so. The Spirit also has the unusual tendency to talk in rhymes.
