If modern Eggman gets 2 Egg Fighters, then Classic Eggman gets 2 Egg Robos! This great 3 pack is the perfect opportunity to get the USA's first classic style Eggman action figure! He looks good from here, but can have a few flaws. Watch out for his sleeve buttons, some of them have 2 of the same sleeve (ie: 2 rights) making the button in the wrong place for the wrong hand.
Eggman himself is a fun likeness. He's very simple, very true to the original Sonic 1 look, including being nearly sphereical. He has no mouth (as expected), nor does he have knees. However, they did give him elbow joints, and he can balance enough to pose as his feet are pretty long. (see below) The EggRobos are a little poor, though. They won't hold their gun (it's strapped to them, in the package) though the gun has nice detail, but is un-painted. Notice the egg robo only has 3 fingers, just like in the game. The shoulders will articulate, but nothing else will. It also will not stand without support due to balance/weight/feet issues.
As mentioned above, the Egg Robo is meant to stand ONLY when holding his gun. However, his hand doesn't hold it at all. The solution is right in the box for you. Simply take the clear rubberband that held the fighter in the plastic, and wrap it over the hand & gun handle as shown at left. It is nearly invisible, won't stain like some glue-tacks, and will last about 1 year before the plastic breaks down. Alternately, the gun can be looped over one hand.
With this comparison shot, you can see classic Eggman is shorter than modern, and that he is almost a sphere, even when seen from top & bottom.
