The Blue Dragon is a mini-boss, Enemy in Demon's Souls.

The Blue Dragon first appears in 1-1, guarding some treasure in a grassy area before the bridge guarded by many soldiers. It disappears from 1-1 if the Boletarian Palace has Pure White World Tendency. It cannot be killed in 1-1, as, unlike the Red Dragon, it does not have a hit box to register damage. It will not actively attack the player, but its swinging tail deals very high physical damage.

The Blue Dragon later appears in 1-4, periodically breathing fire as a stationary hazard. It first appears sitting atop the battlements in front of the palace keep; its fire breath is considerably stronger than the Red Dragon's, but it will also kill the Fat Officials along the battlements if they are in the way. If the player gets too close to the Blue Dragon or reduces its HP by 50% while it's on the battlements, it will fly away and land atop the keep itself while breathing fire down the stairs. If Biorr is not dead or hostile to the player, he will appear the first time this happens, charging into the dragon's path and firing his crossbow at it. If the player equips the Ring of the Accursed, stands out of range of the fire and away from Biorr, and is willing to wait several hours, Biorr can kill the dragon on his own. Otherwise, the player will either have to fire arrows at distance or close in to just under the keep's entrance to get in range to fire spells (items like throwing knives are too weak to actually kill it). It can be killed eventually with ranged attacks like ranged spells and arrows. If the player did not reduce the dragon's HP to 50% beforehand or has low attack power with his/her weapon of choice, there is a strong risk that the fire will eventually kill Biorr.
