Here are a variety of match ups I thought of in my spare time.Note: The FF 4 are from the SNES version called FF2.
Level 20:
Fighter vs Dark Knight Cecil
Black Mage vs Palom
White Mage vs Porom
Black Belt vs Yang
Thief Vs Edward
Red Mage vs Tellah
Level 50/99
Knight vs Paladin Cecil
Black Wizard vs Adult Rydia (summons disabled)
White Wizard vs Rosa
Master vs Yang
Ninja vs Edge
Red Wizard vs Tellah
I tried to make it even. I know some characters are up there twice but oh well just pick 1 winner for each fight.
My answers:
Dark Knight Cecil
Palom
White Mage
Yang
Thief
Red Mage
Paladin Cecil
Adult Rydia
Rosa
Master
Edge
Red Wizard
Tell me what you think!
