Barbariccia Being Summmoned.
Barbariccia (バルバリシア Barubarishia) is a summon in Dissidia Final Fantasy. She is summoned as a counter to an opponent's summon and exchanges the summoner's and the opponent's Brave by using her signature attack Maelstrom. Her original artwork from Final Fantasy IV is used in this game. Barbariccia can be obtained on the third stage of the Shade Impulse III storyline.
Trivia
- Like the other Archfiends, Barbariccia seems to act as a "counter" version of one of Final Fantasy I's Four Fiends, who work on timers. Specifically, Barbarriccia's Maelstrom works much like Kraken's Water Arcana; both exchange the two combatants' Brave. Interestingly, both Barbariccia and Kraken are the third of the "fiends" encountered in their respective games.
