Geozard

Geozard is an enemy in Spirit Tracks. These enemies are also known as River Zora, which also appear in Phantom hourglass'. They boast powerful armor and shields that are capable of deflecting any initial attacks. In order to be defeated, Link must first command a Phantom to engage it in combat, distracting the beast and leaving it open to attacks from behind.

After acquiring the Whip Link can defeat Geozards by himself. He just needs to use the Whip to snatch their shields and then attack them with his sword.
