Theresa Agotti was a graduate student in physics when a portal experiment in her university suffered an explosion. Theresa was filled with negative energy from the dark dimension that the portal had contacted. She later found that she could reach into that dimension and use its negative energy properties for her own purposes. Additionally, she can store objects in a dimensional pocket and pull them out at will. Theresa has an avid interest in archaeology, and enjoys exploring caves and ruins.
