The possible voice actors of the characters who debuted here if it gets an English dub (except for Ishtar, Ereshkigal, Jaguar Warrior, and Gilgamesh):
- Merlin
- He was voiced by Khoi Dao in the Apocrypha dub so they might stick to that. However, in case Merlin's VA gets hit with The Other Darrin like in the cases of Gilgamesh in Fate/Zero (from Grant George to David Vincent), Mordred in Fate/Apocrypha (from Julie Ann Taylor to Erica Lindbeck), and Kirei in Fate/Extra Last Encore (from Crispin Freeman to Armen Taylor), here are the other possible choices:
- Erik Kimerer
- Brandon Winckler
- Mark Whitten
- Sean Chiplock
- Nicolas Roye
- Brian Beacock
- Alejandro Saab
- Yuri Lowenthal
- All jossed. Merlin is going to be voiced by Robbie Daymond.

The Opening Theme will be done by a Female Singer.

The Ending theme will be done by either a Band or Female Singer.
- uru
- Aimer
- FLOW
- Granrodeo
- Confirmed for the female but jossed for all those choice above. Eir Aoi (1st ED) and Milet (2nd ED) will do the ending.
There will be a Special Ending theme being sung by Ushiwakamaru's VA, Saori Hayami.
- Possibly will be heard during her character's supposed Heroic Sacrifice since she will come back as Tiamat's child.
- Jossed. But if it had, it will hear on Benkei's Heroic Sacrifice when she became Tiamat's offspring.
Ereshkigal will have a British accent in the dub ala Rachel Alucard.
- To emphasize her Tsundere aspects and differentiate her voice from Ishtar's.
In relation to the above WMG, the English dub cast would be from Funimation
- In regards to Funimation playing a part in the localization of the anime. For instance Justin Briner might voice Fujimaru instead of Griffin Burns.
- Then again, there are instances that the LA-based Voice Actors have reprised their roles in other anime like Isekai Quartet and the Tales of Zestiria the X so it is more likely that Griffin Burns will reprise his role as Fujimaru.
- Jossed. Bang Zoom! Entertainment will dub it as usual.
There will be a season 2
- 20ish episodes to cover all of the Babylonia arc will be tricky and run the risk of a Compressed Adaptation. However, if they do a second season, they can properly adapt the whole story. It will likely be called: "Fate/Grand Order - Absolute Demonic Front: Mesopotamia", like in game.
- Adding to that season one will likely end with Gorgon's defeat and the real Tiamat's awakening.
- But since episode 11 covers chapter 11, it will be unlikely to have a 2nd season since the second cour will cover the rest of the chapter.
Ibaraki-Douji will actually show up during the lead up to the Finale:
- She'll either make a cameo, or have an Adaptation Expansion where she'll actually help out in some way.
