This was what I built for the BZPower combo build I was able to take place in. The two sets we were given were 75117-1: Kylo Ren and 70786-1: Gali - Master of Water.
Overall I am quite proud of it, and it (arguably) came in second place (if only I had used that blasted Kylo Ren helmet...).
As for inspiration behind it, I suppose it is some kind of digging rahi, using its powerful claw-like hooves to tunnel through the earth in search of food. In case of attack from another rahi it can use its clubbed tail to defend itself.
Someday, perhaps, I'll try and revamp it... Hmmmm...
