Super strength, speed, and agility in any environment, but additionally has moderate reality warping abilities within a DollHouse. Any building she remains inside of for 18 consecutive hours becomes a DollHouse, and will appear unchanged from the outside ((usually)) but becomes an impossible space that alters itself to her fancy inside. Once she leaves, the dwelling will return to normal.
Does not appear to be actively malevolent, but is still a child that cannot yet grasp the consequences of their whims and emotionally-driven actions, so care and caution must still be exercised. 

Addendum: Be warned. Dollhouses do not follow our Rules. Those harmed, altered, or killed inside of one may not recover, revert, or reincarnate if that is what she wishes and they are not removed or her ill will is not swayed in time.
