being an advanced version of the T-1000, Weaver's capabilities are essentially enhanced and improved. Like many liquid-based characters, her base form is a formless mass of liquid metal which she can manipulate into various shapes or weapons. Aside from mimicking humans, she is also able to assume non-human forms or inanimate objects, most infamously, a urinal. She is even able to separate pieces of her body and have them act independently from her, as demonstrated by the pet eel she keeps around. By compressing her form into a snake-like shape, Weaver can move much faster than a human running at full speed.
Weaver also possesses improved battle capabilities as she laid waste to an entire staff by slicing and impaling them with blinding speed and frightening reach, shaping and reverting her form in an instant. She is also able to conduct electricity and channel it through her body without any lasting damage to her frame.
