Wendy is usually shown with the same long hair as the original Wendy, but some drawings depict darker red. She is shown usually wearing goth-like clothing, like a black tank top and hoodie, like the one Robbie wears but with the stitched heart on a sleeve. She is shown in darker blue or black skinny jeans and heeled boots with spikes. She is commonly drawn with multiple ear piercings and spikey earing's. She also wears black, fingerless gloves, similar to ordinary Robbie. Her breast size is also shown to be larger and more pronounced in some drawings.
Wendy is shown to have a rebellious, carefree attitude despite being an obsessed (the is shown in the official V/N that Wendy puts her hand in Robbie's jeans and talk about "what she gonna do tonight" to get his car-keys) .In many pictures, she works with the Gleeful twins. It is currently unknown if she has any feelings toward Dipper or if he has any feelings toward her. It would seem likely, with the fact that Dipper likes Wendy in Gravity Falls, so Wendy may have feelings toward Dipper in the Reverse Falls and kills all Gleefuls to have "fun" with the pinetree.
Wendy is shown to work for Dipper in many cases, and there is a large possibility that she has a crush on him, or that he has a crush on her, since Dipper Pines likes Wendy.
In some pictures, Wendy is shown to be with Reverse Robbie. She appears to be his girlfriend even in this Alternate Universe, so it seems Wendy has a great relationship with him.
Wendy's current relationship status with Gideon and Pacifica is unknown, but it is believed to be bad and hateful, since she is aligned with the Gleefuls.
