Leviathan optical organs appear in the Leviathan Battleship orbiting the Pirate Homeworld. Resembling eyes, they are optical sensors that are irradiated easily by any type of weapon fire. The weapon fire cannot destroy them, however. Shooting them sixty times will award Samus a Friend Voucher titled "Leviathan Humiliated".
"Leviathan optical organ. Target appears to be sensitive to any type of weapon fire."
- Early concept art for Metroid Prime of the creature of the same name depicts many eyes very similar to the organs.
