Actually, that is untrue. In the Marvel comic, sufficient TF weapons could hurt Unicron. One cannon even blew a hole in his foot armor in one scene and Scorponok himself could tear apart Unicron's armor as well with his bare hands. Galactus can hit harder than that.
The thing is, in his physical body, Unicron is severely weakened from his astral form.
