Phantom Guard

In Phantom Hourglass, a new enemy known as the Phantom Guard will stalk Link around certain dungeons. They look like Darknuts, but when they hit you, thirty seconds are taken off the timer and Link loses one heart. In addition, they are invincible until the end of the game. There are "safe zones," however, that the Phantom Guards cannot enter. There are three varieties of Phantom Guards: the blue ones are the slowest, the red ones are faster and can pick up keys and Force Gems, and the gold ones can instantly teleport to wherever Link is. The Phantom Guards are also playable in Phantom Hourglass's multiplayer mode. Here, players will take turn playing offense (Link) and defense (Phantom Guards), trying to collect Force Gems.
