Magcargo's body temperature is approximately 18,000 degrees Fahrenheit. Water is vaporized on contact. If this Pokémon is caught in the rain, the raindrops instantly turn into steam, cloaking the area in a thick fog.
Magcargo's shell is actually its skin that hardened as a result of cooling. Its shell is very brittle and fragile—just touching it causes it to crumble apart. This Pokémon returns to its original size by dipping itself in magma.
