The Malboro appears as an enemy on the Island Closest to Heaven, Island Closest to Hell, Grandidi Forest, and Great Plains of Esthar. It almost always uses Bad Breath on its first turn and, thus, the party should be prepared with good status defense junctions. It can drop the Malboro Tentacle used to teach Quistis Bad Breath as Blue Magic and to craft her ultimate weapon, Save the Queen. The tentacles are also needed to acquire Doomtrain. Malboros can be devoured to boost Spirit. (you can be whatever you want your on quest)

(A demon monster that will try to take your power. You can be whatever you want)
