Gohma (The Legend of Zelda)

 Gohma  is a boss from The Legend of Zelda. It is a giant insect-like creature with a prominent glowing eye. Gohma appears as the boss of Level 6 and several times as the mini-boss of Level 8 during the First Quest.

Battle
Gohma's hard shell repels all attacks, and her weakness is her large, single eye, which is vulnerable to Link's arrows. Due to this weakness, Gohma frequently keeps her eye closed, and attacks by shooting beams from a distance.

Depending on which Gohma is being faced, it takes three arrow shots or one arrow shot to the eye for blue and red Gohmas, respectively, to be defeated.
