Reverend: I hear where you're coming from. However, we're talking completely different evolutionary processes. i look at the Vorlons and future humans as evolving not on a physical level, but on a mental one. Once that occurs, the species is completely aware and able to transcend there physical bodies to become pure energy. When Ulkesh and Kosh duke it out, the bodies are not physical in the normal sense. Their "bodies" are energy. If I remember correctly, the ppgs and electric current were used against the encounter suit, not Ulkesh's "body". Once Ulkesh let loose, it was Kosh and that little bit of Lorien who did the deed.
