Regenerative Healing Factor has some good options, if you want a completely ludicrous power Intangibility is good for that. Those two seem to cover most of the underrated defenses, others i can think of are pretty standard like Supernatural Condition leading to Invulnerability. Beyond that i can only suggest attack powers used defensively.

Hope this helped!
