While I don't dislike the original model of Belial (holding is sword up) I do think he's a little too static in the legs and face for that. He needs to be striding forward or shouting...anything better than silently waving his sword in the air.
I gave the static body the Thunder Hammer and Storm shield combo. For the other two I used spare matching torso, head and legs from two of the Deathwing command sets. One got he resin arms, the sword now pointing down with him looking down the blade (at his defeated foe). The other is all plastic kitbash, he just look tear someone apart.
With the rest I have 15 of 20 regular Terminators done and dusted. The Land Raider is also built. 5 more Termies, the 6 bikes and 2 attack bikes by Sunday I'm hoping...
