The Fifth Hargreeves

You were Reginald Hargreeves' biological daughter. He never told his adopted children about you, meaning the entire Academy didn't know you even existed. Reginald sent you as far away from the Umbrella Academy as possible because he was afraid of your illness. You were insane, and you possessed the power of "Materialization": whenever you thought of an object, it would appear. You were institutionalized and medicated. But after your father's death, you escaped. The Academy knew nothing about you, and everyone distrusted you, especially Five. Now you're pacing the second floor, looking at photographs. Five has been watching you.
