Daigoro (ダイゴロウ, Daigorō?) is Yojimbo's faithful canine companion, always appearing at the aeon's side. Daigoro is actually the manifestation of a fayth that was made of a dog that accompanied Yojimbo's fayth.
Yojimbo often performs attacks himself, but at times he refrains from attacking and his dog attacks for him. As such, Daigoro is a recurring ability originally from Final Fantasy X, appearing both as an enemy ability when fighting against Yojimbo, and as a summon ability when summoning. Daigoro's attack deals non-elemental damage.
The summon ability can be used by Yojimbo after Yuna has summoned him into battle. It deals moderate damage, but its Yojimbo's weakest move. When used, Yojimbo will shake his head before using Daigoro, as if to disapprove of the amount of money the party gave him. He can't use this on long range targets, however.
As an enemy ability, it deals physical damage, and its use is determined in different ways. Yojimbo will use the ability when fought in the Cavern of the Stolen Fayth, and will use Daigoro randomly with a power of 20, which can deal critical damage. When Dark Yojimbo uses the ability, it has a power of 8, but can inflict Poison and Petrify for an infinite time.
Daigoro appears as an enemy ability, as Yojimbo can be fought as a boss, but does not appear as a summon ability. The ability deals non-elemental damage, similar to the summon ability from the predecessor.
Yuna's dog in Trainer dressphere is based on Daigoro, and although the dog attacks similarly it is not the same ability as Yojimbo's.
