Blue Guard

are NaN Enemies in.

Characteristics
NaN Blue Guards are stronger than the CoH:, possessing more health and attack power then their weaker counterparts. Blue Guards carry shields, and they can only be attacked from the sides or back unless the CoH: is equipped. They move to the beat of the music, and share their movement pattern with the Green Guard by preferring to move in the shape of a circle on every other beat, always crouching on one beat before hopping onto an adjacent tile on the next beat.

However, if their path is blocked off by an object or enemy, they will immediately hop away in the opposite direction without crouching, then resume their normal beat pattern for two beats before attempting to form another circle. The circle could be either clockwise or counter-clockwise though the direction they pick is always random. Upon seeing CoH:, CoH:, CoH:, or CoH:, they will become aggressive and leave their post in order to chase them.
