カーン
One of the Bosses from [[Metal Slug]], Specifically from Metal Slug 1 and Metal Slug X.

Karn is one of the pair of super-heavy tanks (the other one is Shoe, its twin.)  created by the Rebel Army for cooperative mission. They are each armed with one main turret-mounted cannon, two sub-cannon turrets on the front, and a missile launcher on the back. Two side-mounted hatches allow soldiers to help defend the tank as well, usually with bazookas or rocket launchers.

In the game itself, Karn fires an HE cannon and HEAT Rounds from its sub turrets, combined with a Rocket Howitzer launching from its rear. The differences is Karn is using a darker or lighter color than Shoe, while the rest of its armaments are identical.
