I don't really care for the Echo Base Trooper too much. I think the Hoth Rebel from TLC was enough.
Other than they're not the same character though. Different uniforms entirely.
I'm a tad miffed his hat isn't removable though. At least I'm betting it won't be. It looks way too snug in the presentation images.
Like I said though, he looks like a decent starting place for a Hoth Luke with some different legs to shorten him a bit, and a new headsculpt. I'm really excited to pick this guy up though so there's some officers to boss around the grunts, who didn't pegwarm here at all anyway... To me, this is win-win. I'd buy more of the Legacy rebel if I could, and now this guy will at least help fill up the Hoth ranks some.
