The Final Fantasy Pathfinder team

My thoughts are currently

Cleric (white mage) with the animal domain to get a Sniper cactus (cactuar).

A Cavalier with an Axebeak (or hunter if gm is a stickler) as axebeaks are damn near chocobos thus being a chocobo knight

Monk >obvious

Wizard (blaster styled to be a black mage)

Ninja to function as trap finder/rogue

Summoner or arcanist (occultist) to summon.

Is this party well rounded enough? Can you think of anything to add or remove or replace?

[DeathlessOne]

Replace the Summoner with a Elemental Ally Druid and flavor each of the Eidolons after Valefor (Air), Ifirit (Fire), Shive (Ice), and *insert choice* (Earth).

Maybe use an Arcanist to replace the wizard as the blaster. Or just a sorcerer. Mages in FF don't tend to know a lot of spells, and if it is more themed for the games that use assigning skills/crystals/materia/etc, the Arcanist's daily spell swapping might be more appropriate.

As for being well rounded... You have six characters. You should be fine.

We built the 8-bit theater version of Final Fantasy one time and had a lot of fun with it.

Black Mage Evilwizardington:

Admixture wizard with a single dip in cross-blooded sorcerer (orcish/draconic). Response to every situation? Fireball. Social or combat.

Fighter McWarrior:

Plain vanilla fighter. Nagaji so Int could be dumped extra low. Believed everything he was told and truly seemed too dumb to die.

Thief:

Elf Rogue. Took a few of the Betrayal feats from Champions of Corruption. Switched sides several times every fight. Many ranks in Profession: lawyer.

Red Mage Statscowski:

Empiricist investigator. Controversial choice but eventually settled on as the class most prone to metagaming. Always convinced he was a character in a computer RPG, and was frustrated he couldn't find his mana bar.

You need a Swashbuckler1/EldritchScionMagusX for a Red Mage, with Weapon Focus: Rapier.

You could probably use Druid as a Blue Mage, except you'd probably have to re-skin Enemy Skill into Wild Shape somehow.

I'd go Cleric/Sorcerer/MysticTheurge for a White Mage, and devote Sorc spells known to buffing.

Crossblooded Orc/Draconic Sorc1/BloodArcanist1/AdmixtureWizardX for a Black Mage.

For a Dragoon, I'd go Cavalier permanently enchanted with a Fly spell, except give him a Dragoon's Cape for "High Jump" teleport 120ft above the target and "Flying Charge" straight down.

Monk, Thief, Ninja, Samurai, and Warrior are easy.

DeathlessOne was spot on with Elemental Ally Druid for Summoner.

If you want to create Squall, that's a Gunslinger1/FighterX with Exotic Weapon proficiency in Gunblade. Cloud would be a Titan Fighter.

Look at FFd20. It's built on the Pathfinder chassis and is still receiving updates.
