Suppress Self

Suppress Self (minor) by Senator Cybus

This is the ability to inhibit one’s own powers and mutant traits, allowing a super being to temporarily become a normal human.
While this might not seem terribly useful, it can be very helpful for characters with powers that are dangerous and hard to manage (such as Control Radiation), powers that make disguise and concealment difficult (e.g Giant or Multiple Limbs) or powers that block the helpful abilities of allies (for example, Immune to Psionics preventing psychic healing). Any unusual physical/mental traits will also be suppressed, as long as they are a result of the character’s superhuman physiology, e.g. the Chronic Pain side effect of the Experiment power category.
The hero can swap between normal being and super being at will. Changing forms requires active concentration, so the hero will not transform if he falls asleep or is rendered unconscious - he will remain in whichever state he selected last.
While in human form, the character’s dormant powers cannot be detected by any known means; even abilties like Scan Powers and See Aura will reveal no unusual physical or mental aberrations.

Range: Self.

Duration: Indefinite. The character can remain in either state for as long as he wants.

Attacks Per Melee: Changing form uses up one melee attack/action.

Bonus: Suppressing certain powers may grant the hero a limited disguise ability, even though his basic form and features stay the same: if a blue-skinned and four-armed centaur switches off his mutant gene, few people would recognise his human self.

Penalties: While Suppress Self is active, the super being loses all of his other powers and unusual traits; he cannot retain useful abilities while inhibiting the ones he doesn’t need.
