The Soul Power is, as its name implies, energy manifested from the soul. In appearance, Soul Power is a kinetic, color-changing energy that Rose channels from her body and often through her scarf, allowing her to control it as a weapon and supplement her attacks with Soul Power. It can be released as projectiles of concentrated energy, zap her opponents, and project temporary copies of herself.
Rose's tarot cards have an additional link to her Soul Power, as seen when Rose quick-changes after a battle with an enlarged "The Fool" card. Soul Power also grants her the ability to seal foes within (presumably blank) tarot cards and seal off evil energy. However, she cannot see a person's fate if they are from the future, such as Ingrid.
Rose has a variety of moves which are shown to use this power; most of them contain 'Soul' within the name. Advanced versions of certain abilities are prefixed by "Aura". Soul Power moves include:
- Illusion Spark is the only move that does not share either naming scheme, although it is likely a combination of Soul Illusion and Soul Spark.
- Allen Snider's Soul Force shares a similar name to most of Rose's move, though it is completely unrelated, making this a coincidence.
