Warrior of the Spiral

So I was inspired by Tengen Toppa Gurren Lagann to do my own original Spiral Warrior character. I'm thinking I might digitally color him but then agian maybe not. The only thing is I just can't seem to think of a proper weapon for this guy. I was thinking a lance but that just seemed to generic, and I don't really want it to be a sword. Too many characters have swords.
