|"Large bombing copter of the Morden's Army. While this is a fighter, this helicopter is used to send V.I.P.s."|
The Hi-Do is a playable unit in Metal Slug Attack. Donald Morden is riding in the Hi-Do. Parts can be obtained through multiple methods, though the fastest is completing stage 16-4 Normal on Attack! as it is rewarded upon stage completion.
It is a fairly weak aerial unit capable of debuffing the attack of enemy units with its special via 4. The primary use of the Hi-Do is to buff Rebel units, as it buffs their health with 1 and damage with 2.
