The Second Generation Attack Helicopter "Hi-Do" is the final boss of Metal Slug: Super Vehicle-001, reappearing again in Metal Slug 3.


The Hi-Do is a gunship helicopter built to serve as Donald Morden's personal transportation. Because of this, it is heavily armored and equipped with various weapons, making for a versatile vessel. In battle it uses heat-seeking missiles and a gatling gun on the front, while Morden himself stays on the cabinet firing from his bazooka. After a while it goes to the top of the screen and open it's bottom hatchet to carpet bomb the whole area.


  • The Hi-Do is based on the real life CH-47 Chinook helicopter.
