So this creature is a basically a "use up the fodder project", but turned into something neat. The idea was a kind of ancient alien, that's survived longer than other xenomorphs. As it grew older, it lost the dome, and became more skeletal. But don't let it's lanky profile fool you, this monster is much stronger and vicious than it's younger brethren!

My recipe:
Head- heavily modified NECA dog alien, the spikes are teeth from a comb
base- NECA diablo, with lots of sculpt work to fill in the gaps (the by-product of my previous king alien)
arms-dog alien with lower diablo arms attached to ball joints
legs-dog alien, feet from Hasbro's old Resurrection alien with joints sculpted on
tail-NECA Clan Leader predator tentacle with sculpt.

Finally finished him up with a slimy mottled gray paintjob, unique from but similar to other xenos.

This was a lot of work, as every square inch of this alien had to be modified and dremeled in some way, even had to replace some of the joints with screws to fit better! I'm happy with the end result though, and thanks for looking!
