Like all Echidna's creations, Witness wanted to destroy everything her original held dear. She was one of the clones that retained some loyalty to her creator, seeing her as likely to cause more destruction than the individuals could on their own.
Witness was unusually patient for an Echidna clone, willing to restrain herself from hurting people in exchange for long-term opportunities. In her interlude, she speculated that different clones had had their personalities altered in different ways by the cloning process, but Wildbow later said that he felt this didn't fit with the other clones' behaviour.
She disliked arrogant people, who reminded her of her - Tattletale's - father. On a related note, Witness retained the same animosity towards Faultline that Tattletale had.
Witness had a grotesquely enlarged head, to the point where she could barely move. Her ability to move her lips was limited, although it improved somewhat with practice. Her arms and legs were small and weak. She had no skull, with an enlarged, visible brain. She had no neck; her head and upper torso, especially her left torso, were fused.
Abilities and PowersEdit
Witness appeared to have the same power as Tattletale, but had a hard time communicating at first, constantly stuttering as she talked.
When Tattletale was momentarily grabbed by Echidna, she created a clone, which she held back inside her. As a result of being "cooked" for too long, she was heavily deformed. She was released when Echidna was briefly trapped underground by the detonation of Coil's base.
After being released from inside Echidna, she met Shatterbird, who was trapped underground as well. Making use of her power to understand the villain, she persuaded her to leave her alive and protect them both from falling masonry. She then tormented her until Vista found them both.
