[Superhero powers] What would be a good defensive/support powerset that isn't a waste?

I write for therapeutic therapy, so I'm not that good, but I have a group of heroes with powers and I don't want to give all of them strong offensive powers.  Out of a group of 5, two have a strong offensive set, one is defense/offense, one is support.  The last one can't be offensive but I don't want it to be weak or make it seem she is sidelined.  Defense/offensive is fine, if it's clearly stacked on the defense side though, or a support/offense powerset.

intangiblity is great for a defense/utility power, and can be easily suited to almost any group, and it has some easy power limiters too if you want(can go through living things, cant use it to fly, blocked by X material, just to list some examples)
