Signaloid

Signaloid are stationary shooting enemies in Mega Man Zero 2. these odd looking enemies turn clockwise occasionally to shoot all three elements (Fire, Thunder, and Ice) depending on which light is shown. It appears in the stages of Phoenix Magnion, Kuwagust Anchus and Sage Harpuia. Its color and attack pattern correspond with the element you are currently wielding, and changes its color if you switch to a different element.

Red = Fire

Blue = Ice

Yellow = Thunder

When it's red, it shoots flames from its right or left side (depending on which side of it Zero is on) like a flamethrower and then shoots a small fireball.

When it's blue, it shoots two snowflakes that rebound off surfaces.

When it's yellow, it shoots an electric blast wich has a short range but splits into two blasts when it is in the same vertical axis as Zero.

If Zero isn't wielding any of the three elements, it stays in the state it is currently in. Its default color is generally yellow.
