Katherine possess two supernatural abilities - the power of invisibility and the power of telekinesis (though, for a time she could not access her telekinesis). After the death of her best friend, June, at the hands of a serial killer in Bikini Bottom, Katherine decides to embark on her own investigation into the man in order to take him down. This pursuit puts her at crossroads with Shadow, who she ultimately stops from murdering his father, Mayor George Coyne. Following Shadow's death in the mayor's house explosion, Vivian convinces Katherine to leave the scene and let her and George deal with the police and media. Vivian tells the media that a hero named 'Miss Appear' saved her and George from Shadow. Following these events, Katherine seeks medical help for her Clinical Depression, re-enrolls in High School to finish her senior year, and becomes a Detective for the Bikini Bottom Police Department. A year later, Katherine becomes haunted by hallucinations, which she initially believe to be Shadow's doing. Eventually. Katherine discovers that Shadow is not the person behind her hallucinations, but rather her brother, Michael Cross. Eventually, Michael traps Katherine in an hallucinated reality, but she comes to override this conditioning, convincing Michael to free her, Molly, Marilyn, Analise, and himself from the fabricated world. At the end of the Season 2 finale, Katherine abandons the 'Miss Appear' identity, embarking on a road trip with her now-girlfriend, Analise.

Analise Rogers / The Sightress 

(Recurring Season 1; Season 2 - Present) - Analise first appears in the third episode of Season 1, "It Should Of Been Me", where she is attacked by Shadow, but manages to survive after a rising sun disables Shadow's ability to kill others. Analise had apparently made headlines in Bikini Bottom by claiming to have the psychic ability to see the future, which is how Shadow found out about her. The character originated on another teenj12 show, "The Bikini Bottomen" , which was initially intended to take place in the Teenjverse alongside Miss Appear. However, after Bottomen was canceled, the show was severed from the shared universe, with Analise's history there being 'retconned'. Following her almost death, Analise is admitted to a hospital on a private floor. Shadow still manages to find her, rampaging his way through the hospital. Analise receives help in escaping him from Katherine Cross and Johnny Flaire. She is eventually moved to two different private facilities - one where Shadow attacks again, killing other powered patients. Once again, Katherine intervenes, and Rogers joins her and Vivian Coyne as they flee the facility. In the last quarter of the season, Analise joins Katherine's crusade in finding Shadow, which increases intimacy between the two women.

In Season 2, Analise and Katherine finally begin to admit their feelings for each other, but Katherine is hesitant to start anything due to the hallucinations that she is suffering (which she believes are caused by Shadow). Analise helps Katherine investigate the source of her hallucinations, with the two sharing their first kiss in the midst of things. In the fifth episode of Season 2, 'Killer M', Analise has a vision of Vivian and herself being cornered by an assassin. This leads Katherine and Analise to charge over to Vivian's home and attempt to rescue her. In the process, Analise is shot by Killer M (Mikey Merlin), and is rushed to the hospital where she begins to recover after a tough night. After Analise gets out of the hospital, she continues to be a source of support for Katherine, and even leads a search for the hero after Killer M had kidnapped her.

Johnny subsequently moves back to his home town of New Coral, after a tearful goodbye with Katherine. Johnny returns in Season 2's 'Sinisters', after Analise seeks him out to help find a missing Katherine.

Following their initial encounter, Shadow makes attempts to find and kill Katherine, while also accidentally falling in love with a young nurse, Marvin Long.

In the end, Shadow commits suicide by remaining in George's home when a bomb was set to go off (one planted by himself, ironically). Shadow 'appears' twice in Season 2. Once in 'Mister Appear' inside a hallucinated reality, where he is straight-A, bookworm, living with his mother. He last appears in the Season 2 finale, once again in a hallucinated reality, where he turned out to be 'normal' instead of a depraved serial killer, and shares a fond relationship with his cousin, Katherine.

Eventually, Shadow turns on Vivian and tries to murder her, but she is saved by the interference of Katherine Cross. Vivian soon reveals to Katherine that she is her aunt, and that Shadow is her son. Katherine eventually forces out of Vivian that she was helping Shadow in his escapades. Feeling guilty for her part in Shadow's killing spree, Vivian decides to help Katherine stop Shadow, in order to save George (who she still has conflicting feelings about).

She and George mourn his dead body, but have to regain their composure when everyone hears police sirens.

He reveals this to Vivian, who empathizes with having a marriage end in hardship.

Katherine harbors an intense crush on June, with it being revealed that the two engaged in sexual experimentation on June's prom night. June, however, does not return Katherine's feelings, causing animosity between them (with the added factor of Katherine's depression). June, who worked at the Krusty Krab, accepts a date offer from Shadow (who she didn't know was a serial killer in the making), after he had asked for her number during her shift. During June's date with him (a hike in the park), Shadow murders her, which sets the course for Katherine to investigate June's death, thereby kicking off the events of the entire series. June was a metafish, with super strength powers - a tidbit that her parents had a hard time accepting when Katherine told them this. In the Season 1 finale, June appears to Katherine as a hallucination (following Katherine bumping her head). In the Season 2 finale, June appears in a hallucinated reality created by Michael Cross (Mindcross), in which she and Katherine are in a romantic relationship. When Katherine realizes this reality is wrong, she tearfully bids June goodbye, expressing that this isn't the way things should be and that she had to move on from June at last.

Maddie Morley - June's mother, who is outraged by her daughter's death. In Season 1's "House and Home", she gives Katherine a hard time over the specifics of what happened to June, and also doesn't believe that her daughter was a meta (being disgusted by the very suggestion). Off screen, Det. Dudley Winters delivers her a diary that was kept by June, confirming June's secrets (such as her super powers). A year later in Season 2, Morley appears at Katherine's door on the anniversary of June's death. Katherine lets her inside and they have a heart to heart. Morley is now at peace with what happened to her daughter, and the revelation that her daughter was a metafish. She tells Katherine to keep in touch.

When Katherine begins working at the precinct, Gilbert tries to befriend her, to which Katherine returns the favor half-heartedly. He tells Katherine that he is only a desk cop and looking to be promoted into the action. Near the end of the season, Katherine seeks an unwitting Gilbert out of help in finding Shadow. In Season 2, Gilbert finally gets a taste of being out in the field, but on his first assignment, he accidentally shoots and kills Jackie Merlin, the wife of Killer M. This event weighs deep on his conscience, as shown in "Time Doesn't Ease Pain", where he divulges his guilt to Katherine while the two are being held hostage by Patrick Peterson - a metafish with the ability to emit a knock out gas. In order to get them out, Katherine is forced to reveal to Gilbert that she is Miss Appear, to which he promises to keep a secret.

In the closing scene of the Season 1 finale, Katherine finally starts sessions with Helen.

Marvin returns in Season 2's "Life After", where Katherine runs into him, remembering the fact that he helped patch up her friend, Johnny, after Winters shot him in order to distract Katherine and free Shadow from her captivity. Katherine reveals to him that she is Miss Appear, with Marvin offering to be her private nurse for her superhero-related injuries.

Due to Katherine's interference, Merlin is chased by the BBPD, with officer Gilbert Gutierrez finding his hideout and mistakenly shooting his wife, Jackie. Merlin blames Miss Appear for the death of Jackie (and the loss of his baby to the foster care system), and decides to plot her kidnap, which proceeds in "Dad", following him learning her secret identity from Vivian.
