Seems like a pitch for a doujin fighter. I'd tweak the roster a bit, though. Something like this:

  • Minfilia:
    • Linkpearl
      • Summon one of nine base-class adventurerers to fight for you. Effect determined by RNG.
    • Special - "The Echo"
      • Restart the current round.
  • Thancred:
    • Gladiator
      • Fights with a single dagger.
    • Rogue
      • Pulls out a second dagger to switch fighting styles.
    • Special - "Urgent Business"
      • "Did I mention I have a date?"
      • Leaves the play area until the round timer expires. Forces a draw for that round.
  • Y'shtola:
    • Conjurer
    • Special - "Buzzkill"
      • "I'm smarter than you. Just accept it. "
      • Depletes opponent's Limit Break gauge. Deals extra damage to Yda.
  • Yda:
    • Pugilist
    • Special - "Oblivious"
      • "Specials are supposed to be attacks, right?"
      • Misses the joke completely, dealing massive damage.
  • Papalymo:
    • Thaumaturge
    • Special - "Always looking out for her"
      • Gives Yda a major combat bonus
      • No effect in 1v1
  • Alphinaud and Alisaie:
    • Bookworm
      • Fights with basic ACN spells, but no pet.
    • Special - "My Own Path"
      • Alisaie walks off, leaving Alphinaud alone.
      • Offscreen support effect, varies with Coil completion.
  • Yugiri:
    • Ninja
    • Special - "Her True Face"
      • Removes her mask.
      • No other in-game effect.
  • Moenbryda
    • Marauder
    • Special - "I Finally Understand"
      • Only useable at exactly 1% HP.
      • Instant victory if used in final round, otherwise forfeits match.
  • G'raha Tia
    • Archer
    • Special - "The Light of Hope"
      • Awakens G'raha's true potential.
      • ...But mankind isn't ready for it yet. Forfeits match, regardless of score.

Any other ideas? I sort of ran out before I got to the GC leaders and Empire characters.
