Megami Tensei/Willpower

Background

Willpower is an ability in the Megami Tensei franchise that humans innately have. Though humans are normally the weakest of all species due to their Observation and Willpower, they can fight against the greatest threats.

Abilities

• Sheer Will: Naturally users of willpower tend to have some of the strongest willpower in their respective universes.

• Statistics Amplification: A character willpower in SMT allows them to increase greatly in strength allowing them to harm enemies they couldn't even scratch before and survive attacks that would have originally kill them, the will of one's friends and allies around them can invigorate one to become far more powerful then before.

• Regeneration True-Godly; Characters that get completely erased by demons to the point that everything returns to nothing (otherwise known as returning to The Axiom) but with enough willpower one can regenerate back to life.

• Resurrection: Everyone praying for Raidou bolstered his willpower up, allowing him to resurrect and regenerate part of his body.

Resistances

• Pain: Users with high willpower can fight through pain that's so unbearable that it makes one unable to move, constantly take damage and being unable to control their demons well.

• Memory Manipulation: Noted by Polaris that all of the memories and relationships of the Devil Survivor 2 cast will be completely erased if they choose to restore the world, requiring a strong willpower to retain them.

• Empathic Manipulation: Humanity's willpower allows them to ignore the voice of God, with Zelenin needing to sing a stronger sword to wipe their willpower away.

• Truth Manipulation: Users with huge willpower can ignore the truths created by YHVH due to the bonds with their friends.
