Took longer then I thought because I was busy working on something else. But here you go.
The deviation in style from Var’s is to use slightly different shapes to the original designs, and make it slightly more bulbous and less sleek. I also made the legs shorter, and I’ll get to that in a bit. The design probably would need some revision to fit in witht the rest of the characters a little better.
The weapon design is based off @DarkHenrik and @Oomatu’s rahkshi weapon designs, but looks more like a scythe than a pickaxe here because of its size.
Considering in canon he comes from a royal family, I wanted to make it seem like he’s trying to cling on to his sense of importance after turning into a giant yeti-rage-monster by using a red cloak and a crest on his chest.
He also refuses to walk on four limbs, despite his transformation forcing him to walk like a gorilla, probably hurting his back. It’s also why his legs are stubby and short in comparison to the Toa.
A size comparison to Lerahk and some pose/posture tests:
As for wether a cape could work on an Axl-fig:
@Kaituhi tested it out for me and works surprisingly well. Here are the several attempts at making a cape that fits:
And here are some crude measurements, for the curious.
Hope you enjoy.
