Kanan is the main antagonist of Metal Slug: 2nd Mission.
Kanan is a commander of the Rebel Army's Phantom Squad. He commanded the construction of the Rebel Rocket to bond the Rebel Army and Martians' relationship. In actuality, he intended to use the rocket for his own personal gain as he was the only one boarding it.
Kanan makes his first and only physical appearance when he pops out of the destroyed Rocket UFO. Beforehand, he is briefly heard in Mission 6 (Turbulent Transmissions) in an intercepted call and mentioned in Mission 37 (Lone Assault) by Margaret. Kanan uses a rifle to fend off against Gimlet and Red Eye. Unlike other antagonists, he dies in one shot.
