Unknown Power (潜在能力, Senzai Nōryoku)? is a feature in the early Persona games.
Megami Ibunroku Persona
Unknown Powers are special abilities that are activated when a Persona-user is in low health. Those abilities are activated in the middle of battle, interrupting it. Unknown Powers are obtained by fusing specific Orders under certain moon phases, but they can only be activated if the Persona is at least at Rank 6 and has Best affinity with the user. There are four types of Unknown Power: Recovery, Nullification, Revival and Attack.
HP must be equal or lower than the percentage specified.
|Remaining HP||Activation Chance|
The Persona will heal a certain amount of HP and/or SP and may even heal its host from ailments.
|Moon Phase||Second Demon's Order||Effect|
|HALF||Night, Yoma, Fairy||Recovers 50% HP|
|3/8||Haunt, Spirit, Grave, Foul||Recovers 50% SP|
|FULL||Night, Yoma, Fairy, Divine, Fallen||Recovers 50% HP and SP|

A Persona with this power will revive its host with full HP and SP. After reviving the character, the Persona returns to Rank 1, losing all of its learned skills (though those can be relearned by ranking up again). In addition, the Persona can't rank up until the end of the fight, which can be detrimental if triggered during a boss battle. However, the Persona does not lose the stats it had before and, as it ranks up, those stats can rise even more.
Personas have different Growth Rates, meaning that which stats are increased at each rank and by how much are already predetermined. Some Personas, such as Cu Chulainn only see an increase in Strength and Magic Attack, while others like Lilim see an increase in all stats. It's possible to abuse the revival power on those Personas to create a Persona with maxed stats.
The revival power has a 25% chance of activating and can't be triggered if the character is killed by a reflected attack.

Inflicts 999 points of non-elemental, unblockable damage to all enemies. This power differs from the others as it is specific to certain Personas. These Personas gain the Attack Power automatically when fused and cannot gain other powers even if the conditions of their fusion allows it. Those Personas are: Durga, Susano-o, Hokuto Seikun, Bishamonten, Lucifer, Satan and Illuyanka.
Persona 2: Eternal Punishment
Unknown Powers are special skills that are unlocked once the Persona gets a Mutation saying that an "Unknown ability [has been] awakened". Once this occurs, when the Persona-user's HP goes below 1/8th, takes over 3/4 of their health in damage, or dies, the unknown power will be activated. The effect will also differ depending on the affinity between the Persona and its user. Every Persona has a different kind of Unknown Power out of 6 different kinds, and cannot be changed.
