Quick conversion today, using a Reaper Bones Bathalian body and arms with a head swapped on from a Troll Forged Games alien head.
I've done quite a lot of Bathalians over the years, in part because the arms and heads swap easily between the three different Bones sculpts.
It's also very simple to find other heads that can be swapped on, obviously.
They are quite large, which offsets the usual Bones white tendency to flex and bend despite the relatively thin limbs.
This one's mounted on a 60mm base and positively looms over the Frostgrave barbarian here, who's mounted on a 25mm base.
