D0g is a summon in Kingdom Hearts II ½.
Story[]
D0g is unlocked when Sora finds his charm in City of Angels.
In Battle[]
D0g is a very powerful offensive summon. He mainly uses his huge arms to pummel enemies into submission and is capable of devastating combos. Occasionally, he'll slam his fists into the ground to create a powerful shockwave which sends enemies flying into the air, allowing Sora to attack with aerial combos. D0g Paddle, which references "Dog Paddle" (a reaction command used against Cerberus in Kingdom Hearts II) has Sora ride D0g, shooting Thundaga bolts as D0g charges into enemies.
