Other appearancesEdit

Kingdom Hearts IIEdit

Axel uses Prison of Flames as an attack during his second battle with Roxas at the Basement Hall. It cloaks the Basement Hall's floor in magma and drains Roxas's HP by 1 HP every five seconds. It can be removed by using the Clear Light Reaction Command. In Kingdom Hearts II Final Mix, the version used by Axel's Data Replica drains Sora's HP by 6 HP per second until he is at 1 HP, and Axel cannot be defeated as long as it is active.
