Bionicle? Hero Factory? Something else?

What is this? I don't know a thing about Bionicle, so of course I bought like a 10 pound box of them for $20 at a garage sale. This one caught my eye due to the size - probably about 15-18" tall when completed? I think the other arm and head are in the box. Anyone know what it is? I don't even know where to look to find out knowing very little about these in the first place.
