An Argo is a new boss enemy in EDF 2025. Your first encounter with one is late in the game (mission 67). They will only be encountered twice throughout the campaign not including DLC.
The Argo is a massive battleship which has two transformations. The first is the battleship form which is its flying form. With the flying form the Argo can move around much easier than when it is on the ground. It has numerous attacks in this form, mostly explosive; volleys of huge beams fired from its underside cannons, exploding projectiles similar to those fired from Deroys and artillery Hectors, and spreads of slow-moving machine gun fire.
The second form of the Argo is the Giant Robotic form in which it no longer flies. This form is one of the largest robotic enemy you fight in the game, said to be three hundred metres (980 feet) in height. Once the Argo lands it means you have done about half damage to it or more and are close to destroying it. The Argo will have two more attacks in this form, it will shoot a massive green projectile that has a large blast radius, it is safe to assume that this is its most powerful attack, though it is hardly ever aimed at the player character and a attack where it floats into the air and spins around firing its arm cannons at the ground though this move is a rare one.
- Argo is the ship of the mythical ancient Greek hero Jason, and the source of his crew being referred to as Argonauts.
- The Argo's overall look and aircraft-robot transformation is inspired by the Meganite robot Laguiole from Sandlot's 2002 game Robot Alchemic Drive.
