This glitch works in Double and Triple Battles, and is extremely crippling to whoever is the recipient of its effects. When someone is using Sky Drop and Gravity is used while the two Sky Dropping Pokemon are in mid-air, the two Pokemon will be forced back to the ground. However, the target of the Sky Drop move will not be able to do anything, as if it was still up in the air: at the same time, however, it can be hurt. In other words, it is now a completely unfunctioning Pokemon whose only purpose is to be KO'ed.
