That barrier has plot power just like the birdcage.. Let's say Psiorochi throws at him the same ray she spammed vs Tatsumaki, the one which sliced a portion of earth, what donyou think will happen?
Anyway other counrers are speedblitz, throw Barto and his ball into space or in the ocean, lava, cover with acid like for fuhrer ugly (sooner or later that barrier will have to stop) etc.
