Thankfully for this big metal guy, Toph is already aware of the existence of enormous metal people - you can thank a certain Transformer for that. That fact, that's who she thinks it is when she senses him approaching from yards and yards away down the street.

But when he talks and it's not the same voice, it makes her stop and look at him. Even though she can't see, her expression of surprise isn't any different, eyes wide and eyebrows up.

"Huh? There are more of you??"

But he's kinda different from Wing. He's not entirely made out of metal. Her surprise twists into confusion as she listens for him to explain himself.
