She debuted during the episode airing on October 30, 2009, under an alias, later revealed to be the daughter of Sheila Carter (Kimberlin Brown) and Tom Fisher (Roscoe Born).

Daisy later raped Daniel Romalotti (Michael Graziadei), drugging him to believe he was sleeping with his then wife Amber Moore.

In 2012, Daisy was released from prison by Avery Bailey Clark (Jessica Collins) and reclaimed her daughter, later earning full custody.

She and her brother, Ryder Callahan (Wilson Bethel) arrive in Genoa City to get revenge against Lauren Fenmore (Tracey E. Bregman) for killing their mother, Sheila Carter (Kimberlin Brown).

They work with their aunt Sarah Smythe, Sheila's sister, to commit a series of crimes and ultimately kidnap Lauren and Jana Hawkes (Emily O'Brien), their brother Kevin Fisher's (Greg Rikaart) wife.

Daisy then found herself attracted to Daniel Romalotti (Michael Graziadei), who at the time was married to Amber Moore (Adrienne Frantz).

While Ryder and Daisy both blame Lauren for their mother's death, they do not seem to realize that their half-sister, Mary, cut Shelia out of her life because of what she was.

Daisy also stayed briefly at Daniel's apartment, and later gave birth on New Year's Eve with Jana at her side.

Avery then teamed up with Heather Stevens to arrest Daisy for not helping Phyllis when she was miscarrying, and in return Daisy threatened to reveal that Phyllis hit Paul Williams (Doug Davidson) and Christine Blair (Lauralee Bell) with a car eighteen years prior.

Daisy was unaware of Ricky's death, and tried to convince the doctors to release her, which they refused to do without legal proof of her true identity.

After she did so, the doctors received the results of her fingerprint scan, and Ronan Malloy (Jeff Branson) got a call about Daisy's whereabouts.

A woman claiming to be Daisy's mother checked her out of a mental institution, signing the name "Sheila Carter" on the release form.
