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 original size by dripping itself in magma.
Sapphire
MAGCARGO's body temperature is approximately 18,000 degrees F. 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.

The shell on its back is made of hardened magma. Tens of thousands of years spent living in volcanic craters have turned MAGCARGO's bodies into magma.

Dark Magcargo: The shell on its back comes of easily, exposing the flames running through its body.
When used by a Ghost-type, the user sacrifices half of its max HP to sap the target by 1/4 of its max HP per turn. When used by anything else, the user's Speed is decreased by 1 stage and its Attack and Defense are increased by 1 stage.
Can be used up to three times to power Spit Up or Swallow. Also raises the user's Defense and Special Defense by 1 stage each. Stockpiles and the defensive boosts are lost when these Swallow or Spit Up is used or the user switches out. However, the boosts can be Baton Passed.
This move only works if the user has at least one Stockpile. Restores 1/4 of user's max HP with one Stockpile, 1/2 of user's max HP with two Stockpiles and fully restores the user's HP with three Stockpiles.
This move is temporarily replaced by the target's last move; the replacement move will have 5 PP and become part of the user's moveset until the user switches out or the battle ends. Mimic copies attacks even if they miss or the user has immunity toward their type; it cannot copy itself, Struggle, Transform, Sketch, Metronome or moves that the user already knows, and it will fail if the target has yet to use a move.
The user takes one-fourth of its maximum HP to create a substitute; this move fails if the user does not have enough HP for this. Until the substitute is broken, it receives damage from all attacks made by other Pokemon and shields the user from status effects and stat modifiers caused by other Pokemon. The user is still affected by Tickle, Hail, Sandstorm and Attract from behind its Substitute. If a Substitute breaks from a hit during a multistrike move such as Fury Attack, the user takes damage from the remaining strikes.
Almost always goes first. The user is left with at least 1 HP following any attacks for one turn, but the move's success rate halves with each consecutive use of Protect, Detect or Endure.
