The Spark is an enemy in many of the games in the series, mostly the handheld games. First appearing in A Link to the Past, starting in the Tower of Hera, the enemy was invincible and could only be avoided. It can be killed in Link's Awakening, Oracle of Ages, and Oracle of Seasons by means of either Magic Powder or the Boomerang. Killing them will turn them into Fairies that replenishes Link's health. They can also be defeated with a Boomerang in the The Minish Cap.
- "Found within the many dungeons of Hyrule and Koholint Island, Sparks are fast-moving entities that zip along the edges of blocks and walls searching for food." — (The Great Hyrule Encyclopedia).
