Jumbo Flan (Final Fantasy X)

Jumbo Flan is a special enemy in Final Fantasy X. It is bred in the Monster Arena once three of each type of Flan-species fiends have been captured.

At first Jumbo Flan will be a perplexing enemy, and defeating it may seem impossible. It is immune to physical attacks and will absorb all elements. It also has Auto-Reflect and will be in Haste status at the start of the battle. Ultima is a good choice if it has been obtained, as this spell cannot be reflected. Using Doublecast, and then following with Copycat from another strong magic user will prove effective. Slowing the monster down by bouncing Slow off a reflected ally is a must.

Another useful way around Jumbo Flan's defenses is with Anima's Pain attack, which is non-elemental and non-physical.
