User blog comment:SonicFan/Ben's fear of peacocks/@comment-7052631-20130311012322

In Ben Again we see this confirmed by Rook. As odd as it may seem, it really is just thrown in for comic relief. Besides, Ben already beat Vilgax, but can you picture him using Kickin' Hawk and beating the feathers off of peacocks?

If push comes to shove though, I suppose he could always turn to his grandpa or gwen for help.
