I think the current voice actress is doing a superb job and I'm happy with the decision, just want to say that.

But every time I look at Lightning I can't help but think that the voice of the Major (Motoko Kusanagi) from Ghost in the Shell would be a perfect fit. Does anyone else believe Mary Elizabeth McGlynn would be a great choice for this role?

Would I like to see Lightning sing Alex Theme?

Sure, why not :)
