A Metal Primid (メタルプリム, Metal Prim) is a Primid made of metal. They have the same moveset as regular Primids, but have more health with poorer mobility. The most distinguishing feature of the Metal Primid is their immunity to flinching and knockback from all attacks but throws.
Metal Primids often appear in groups of two, and pose a much larger threat than regular Primids. While their attacks aren't any stronger, and they are slower with less mobility, they have more health, enough to regularly sustain multiple blows before being KO'd, and they are immune to flinching from all non-grabbing attacks. Their immunity to flinching makes it difficult to fight Metal Primids without getting damaged, as they will attack the player through their attacks. Metal Primids can also reflect weak projectiles, which often renders pelting them from far distances with projectiles ineffective. However, Metal Primids are vulnerable to being grabbed, and throws will produce the same hitstun and knockback to them as they would to normal Primids. Exploiting this is generally ideal to safely fight a Metal Primid without sustaining damage from them.
A Primid covered from head to toe in metallic plating. It cannot be knocked around with conventional attacks due to its hard and heavy nature--we're talking ALL metal, including the frilly feather on its head. On the flip side, the weight of the metal inhibits this Primid's movements. Like a normal Primid, a Metal Primid will also rely on hand-to-hand combat.
