The xenomorph minifigs are interesting things.
There is a lot of printing all over the bodies of these things, even on the back, which gets covered up almost completely by the shoulders/back/tail piece.
The head is its own piece with a lower jaw piece connected to that, so it can open and close a little bit!
Looking at
>>6707270, there appears to be another version of the xenomorph with a skeleton (?) torso and General Grievous legs. Maybe I'll get a few of those too? There's no way they'll have the same printing detail, but maybe the exotic pieces will work better overall as the alien design.
I'm just happy to have Gieger's Alien minifigs.
