The Metal type is one of the eleven TCG types. It is represented by the color silver, and symbolized by a gear or bolt.
The Metal type was introduced in the Neo Genesis set, along with the Darkness type, when the Steel and Dark types were added upon Pokémon Gold and Silver's release. Prior to this, there were no Metal type cards (while Magnemite and Magneton currently can be Metal types, they were previously exclusively Lightning types).
Like the Darkness type, the Metal type has its own Special Energy, Metal Energy. This type of energy affects only Metal type Pokémon, and allowed damage done to it to be reduced by 10. There was no basic Metal Energy card until the Diamond & Pearl set when one was finally released.
