>>7592371'Claw guy' is Pheyaos, which is a brand new sculpt that only just debuted last month. So there is a lot less known about it than other figures.
It builds really well with axis joints, but unfortunately all the light green axis joints are already sold out this drop. The clear green should match pretty good with him though, especially if you go for the clear Pheyaos. It also builds pretty well with the 'Traveller' sculpt, such as Pheyden in this drop.
If you get multiple Pheyaos, they are pretty good at making some eldritch-like monster builds, like the attached. Keep in mind that there's no way to get around the asymmetry. That right hand can only be a right hand; you can't buy two Pheyaos and put a hand on each side to get rid of the tentacle, it looks terrible.
If you really want to see what the sculpt can do, search 'Pheyaos' on Instagram. It's been fairly positively received, unlike the last new sculpt, but the building community hasn't taken off with it yet. It looks great in its default build, as you can already tell. What kind of other stuff did you want to know?
