After looking at the Grok Rider's concept art, I got the Idea for this thread.
I figured out that Me-burq-Sa, along with the Groks are rather easy to take off of their mounts.
So I am thinking of putting a squad of three Grok's on 3 of Me-Burq-Sa's horses.
Once I get some more Grok's and Me-Burq-Sa's, I'll post some pictures of my creations.
Feel free to try yourselfs if you like the idea.
