The EU came out with a lot of stupid retcons over of the years, but the one that makes this guy

and this guy

one and the same person has got to break a record for being the most pointless, nonsensical SW retcon ever produced.

I've read the comic where the guy with the AT-ST legs makes his first and only appearance, and not only is he a blue alien with a ridged forehead and glowing yellow eyes -- something the guy in the top picture most definitely is NOT -- but there's nothing in the story whatsoever that paints him as being a Force-user -- light, dark, or otherwise.
