Red Giant is an optional boss in Final Fantasy VIII found in Ultimecia Castle and summoned when the player enters the Prison Cell in the Armory and retrieves the Prison Key. In the localized versions, Pandemona can be drawn from Red Giant if the player did not draw it from Fujin earlier.
Red Giant attacks with its Gigantic Sword, but once its HP is reduced to around 9,000 HP or below, it abandons the sword to fight with its bare hands, using the Punch attack. Because of heavily relying on physical attacks, Red Giant is handicapped if inflicted with Blind. The Punch attacks will always hit though.
Another strategy is using Irvine'sShotLimit Break using AP Shot, as its armor piercing ability negates Red Giant's Vit and Spr and deals direct damage by the thousands. Bahamut will likewise ignore Red Giant's defense.
Using Meltdown renders the boss weak to physical attacks. Kamakaze may destroy it in one use, albeit at the cost of its user.
