Chardum uses fire to control its own magnetism and uses magnetic force to control the flammable gases in its body. Normally, it moves using magnetic force and only heats up to breathe fire when hunting Steel-type Pokémon.
When Chardum gather in a swarm, they move in perfect unison as if they were but one Pokémon. The flame that burns at the tip of its tail is an indication of its emotions.
