Not exactly the kind of thing you ever want to have to get used to.
Least he's got his body back
Or DOES he...?
Yeah, I'm going to assume he does, seeing as he's hovering over it.
His body does not have energy though, does it?
I just realized something! Duo could take over Gato and Kraid's bodies, right? So instead of giving him his old body, why not have take over the Federation ship orbiting the planet with the doomsday device and Nack onboard. You'd kill two birds with one stone, because he could stop the device, and capture Nack at the same time! It's perfect!
I like being right, he really is powerful isn't he? I'm surprised he actually lost to Magus...
Duo's EXE form makes perfect sense. Duo is actually a being of pure energy who created his own body. Matter and energy are interchangeable. In the Battle Network games he did not need a body so his soul could simply enter the computer directly.
