If you're talking about Dark Flan simply armor break it. If you're talking about Jumbo Flan (the one in the monster arena) then using Anima's Pain or doublecasting Ultima with all 3 party members is the best way to go.

I assume you're talking about Jumbo Flan since that's the only flan that is immune to physical attacks. However, it absorbs all elemental magic attacks and Dark Flan halves all damage done by elemental magic.
