Wallfire

Wallfires are immobile sentries built by the Chozo which resided on the planet SR388. Now that the Chozo have disappeared, they continue to guard the ruins, becoming active only when an unrecognized lifeforms enters its range of fire. Its weapon consists of a fireball projector that can, strangely, be frozen through the use of Ice Beam technology. They are equipped to handle self-repair procedures after a potential threat leaves the area that they serve and protect.
