Dr. Adrian Walker was a xenobiologist. He was one of many experts interviewed for the television special "Alien Visitation".
Walker seemed to view the visit as a positive experience, stating that the aliens were not that different from humans, believing Chiana's controversial attitude wasn't a big deal compared to what human culture itself produced, and was amazed by Sikozu's gravity defying ability.
- Look, you see only differences... tentacles, a tongue with venom. Everything about him screams 'ALIEN'. Now, close your eyes. Listen. General Ka D'Argo could easily be you or me.
- (About Chiana's thoughts on sex): I'm not a psychologist, but that's rather innocent, hmm? I mean, you get more juice from Dawson's Creek.
