- Playing Against Type:
- Josh Keaton, most well known for playing serious hero types, plays Lann, a dorky Idiot Hero.
- Same goes for Claudia Black, who is usually identified with serious Action Girl roles like Morrigan and Chloe Frazer. Here, she plays a hammy female Leviathan (which makes this a case Hilarious in Hindsight after Final Fantasy XV came out, also featuring a female Leviathan albeit with a more destructive attitude).
- The Other Darrin: In his last voiced appearance, Vivi was voiced by Melissa Disney. Here, he's voiced by Kath Soucie.
- Relationship Voice Actor:
- In Japanese, Lann (Soma Saito) and Reynn (Sora Amamiya) are like a sibling version of Tatsumi and Akame in a far less Crapsack World setting, with Seryu (Kana Hanazawa as Enna) now as a crucial ally.
- Both Reynn (Amanda Leighton) and Rikku are Powerpuff Girls (albeit of two different generations).
- Whenever Pellinore and Tonberry (Steven Barr) get into a conversation, it mostly consists of "Pellinore." "Tonberry."
- Role Reprise
- Both Steve Burton and Doug Erholtz return to voice Cloud Strife and Squall Leonhart respectively, and they're probably used to it by this point. And speaking of Final Fantasy VII, Rachael Leigh Cook and Kari Wahlgren also reprise their roles as Tifa Lockhart and Shelke the Transparent.
- James Arnold Taylor, Hedy Burress, and Tara Strong return to voice Tidus, Yuna, and Rikku.
- Ali Hillis and Troy Baker return to voice Lightning and Snow Villiers. Likewise, Julie Nathanson returns as Chocolina—*ahem* sorry—Chocolatte.
- Caroline Macey returns from the Nintendo DS remake of Final Fantasy IV to reprise her role as Rydia.
- Grant George, Jason Spisak, Keith Szarabajka, Natalie Lander, and Candi Milo return to voice Warrior of Light, Bartz Klauser, Gilgamesh, Terra Branford, and Shantotto, respectively.
- The Wiki Rule: The Final Fantasy Wiki. And the rule itself is mocked in the Mirage Manual entry for Bismarck.
