[Invincible] Why didn't Green Ghost just turn intangible?

When Omni-Man killed the Guardians, why didn't Green Ghost just turn intangible and get away?  Or better yet, turn herself and Omni-Man intangible so he couldn't hurt anyone?  Maybe this second suggestion is too problematic because her powers only work with people she can control or something; it's not very well delineated.  But she could at least have turned intangible herself and gotten away to tell someone.  You might blame her horror at what was going on or her inexperience, but this is the Guardians of the Globe, the world's premier super team.  I find it hard to believe that Green Ghost had never strategized facing a superior foe and planned a getaway or a way to neutralize the foes' strength with her phasing powers.

Omni-Man threw ~~Red Rush's~~ Darkwing's corpse at her, her instinct was to catch him, which required her to be solid, and then he followed it up with an immediate killing blow. It was 100% calculated on the part of Omni-Man.
