I'd argue nothing short of hulk or superman could punch through that mech, and their strength is officially incalculable.

But Erde could seriously mess it up with his abilities. 

See where I'm going?

Alternatively, I'll just scale the defensive properties of the mecha down. That's a solution too. But then it's a walking glass tower, so no more using it in combat :)
