The Tiger Slug is a tiger with sabre-shaped teeth. Two Vulcans are placed on its sides while a large weapons container is mounted on its lower back. The tiger normally attacks by firing its vulcan and rocket launchers simultaneously against distant targets. Those too close to the tiger will get swiped by its claws.
In Metal Slug Attack, the tiger is the one who raised Growl when he was an orphan. Growl uses his spear in conjunction to the tiger's claws. He can feed the tiger a small snack to move it into enemy lines to attack multiple units at once while dropping numerous mines. The tiger is the one who handles all the heavy weaponry.
Like Scotia Amundsen's camel, the Tiger Slug will carry Growl back to base when he is defeated.
