Mod!Sky (Usually refered to as just Sky) is a 19-year-old woman and is main the antagonist of VS Sky by bbpanzu. She is a fangirl of Boyfriend and wants to take Boyfriend as her own girlfriend, despite the fact BF already has Girlfriend as a girlfriend. Her Week includes three songs: Wife Forever, Sky and Manifest. This mod has been through quite a lot due to misinterpretations of Mod!Sky and general confusion about how she worked in her early variations. Eventually Mod!Sky turned out to be an inaccurate interpretation of the OG Sky's personality, as Sky actually hated BF and GF and specifically wanted to ruin their relationship.After Sky uses a "Shift" she ends up in the FNF universe, and after some tinkering, manages to trap Boyfriend and Girlfriend in a white void with her. She seems intensely committed to making the blue haired rapper her own and shows her emotions with a song. After realizing Boyfriend already has a girlfriend and is uninterested in Sky, she gets irritated and attempts to convince him through another song. Upon failing, she decides to force BF to be with her by getting rid of Girlfriend. Sky transforms into her Manifest form and crucifixes Girlfriend, who is unphased and proceeds to taunt and egg on Sky further, resulting in a final clash between BF and Sky. Sky appears as a human with fair skin, magenta eyes and long sky-blue hair. She wears a white t-shirt with a red checkmark contrasting BF's crossed out circle, a blue jean skirt and black boots. She also has a red blush that is visible on her cheeks until she gets annoyed or mad. During Manifest, her demonic form is much more threatening, changing her appearance upon transforming. Her hair is changed to dark gray, her skin is now bluish gray with black arms and sharp claws, her eyes constantly glow red, and her mouth is not visible, with the exception of her singing poses revealing its sharp teeth. However, her clothes remain unchanged.
