Finally finished my captain. A very unused HQ choice in the BA codex, for the price I think he packs a lot of punch...with jump pack and dual lightning claws its 155pts, and with Furious charge he's 5 attacks at WS6, I6, S5, with re-rolls to wound. Oh and he has a 4+ invul.
The arms are magnetic so I can change out the gear in the future. A power weapon and infernus pistol is the exact same points and an equally viable option IMO.
The problem is getting the right hand power armor lightning claw. The only place to get one, is metal, and in a particular veteran blister.
