Nanook is a character introduced in Metal Slug Infinity.
Nanook is a bipedal polar bear with a grenade belt working for the Rebel Army. He's strong enough to dual wield large arsenals and has high agility to jump over obstacles. Nanook shoots his enemies from an AR-10 as his basic attack and from a minigun as his special attack. His AR-10 can knockback enemies while his minigun can freeze them. Nanook is immune to freezing and electric shock.
- Nanook is based on the Inuit deity of the same name.
