Currently on PO, both Hyperspace Fury and Hyperspace Hole do not bypass Substitute. Instead, they deal damage to the Substitute. I have tested this in-game and CONFIRMED that this is a bug. Both moves should bypass Substitute. They deal damage to the opponent behind the Substitute. They do not remove the Substitute.
