Guess Who!

[Gamblet]

Are you found in Dollet?

Are you a NPC?

Do you give an item to the main party?

[Jiro]

No.

mmmmmm not sure how to answer this. I'm not a player character.

No.

[Gamblet]

Are you an enemy?

Are you alive?

Will you make your card move?

[Jiro]

No.

Yes.

Already did

[Citizen Bleys]

Do you have a Triple Triad card?

Are you a Guardian Force?

[Jiro]

Yes, Yes

[Citizen Bleys]

Shiva would be too obvious.

Are you Pandemona?

[Jiro]

No.

[drotato]

Are you quezacotl? o:

[Jiro]

No.

[Citizen Bleys]

Do you play a musical instrument?

[Jiro]

No.

[Gamblet]

Eden?

[Karifean]

Hmm, so it is not an enemy, which rules out Ifrit, Diablos, the Brothers, Cerberus, Bahamut, Cactuar and Tonberry. It is not found in Dollet, so Siren's out too. Pandemona and Quezacotl are out too, since they've already been guessed. You could interpret "not giving an item to the player" as "G.F. has no x-Refine ability" but I wouldn't make that assumption (and I don't think there's a G.F. that fulfills that requirement). So that leaves Shiva, Carbuncle, Leviathan, Alexander and Doomtrain (and Eden but Gamblet guessed that).

Are you Alexander?
Are you Doomtrain?
Are you Leviathan?

[Jiro]

No to Gamblet, and three resounding Nos to Karifean! Keep it up team, almost there!
