Gemini (Final Fantasy X)

Gemini is an enemy in Final Fantasy X. It is found inside Sin and at the Omega Ruins. They always attack in pairs, one blue and one purple. After taking a certain amount of damage, they will use a double, synchronized combo called Double Reaper. Using Armor Break will be useful, as well as casting elemental magic (remember that the purple absorbs water and ice, while the blue absorbs fire and thunder).

It drops weapons with Strength+10%/Magic+10%, and armor with SOS Regen and HP+10%.
