Jasmine is a morally ambiguous character whose goal is to gain a corporeal form on Earth in order to rule it and bring about world peace.

According to her servant Skip (a demon in secret contact with Jasmine, but openly friends with Cordelia Chase), Jasmine arranged for many of the events seen in Angel Seasons One through Four all to align players as necessary in order to create the opportunity to come to Earth.

These included Lorne's arrival on Earth, the passing of Doyle's visions to Cordelia, later Cordelia's transformation into a part demon and her ascension into the realm of the Powers, the birth of Connor, and the coming of the Beast.

Jasmine explains that long ago, the primeval forces that are now considered good and evil took shape; however, the malevolent grew in power and the era of demons began. Jasmine and some of her fellow beings left this world and made themselves content to watch from an alternate reality, only directing the remaining forces for good on Earth and not taking an active part in the battle against evil.

Jasmine was a renegade who decided to take matters into her own hands and impose peace on Earth through mind control. She conquered a dimension filled with a race of insectoid demons as a rehearsal before going to Earth. Jasmine, known to these demons as "The Blessed Devourer," tinkered with the demons' evolution and society, but eventually abandoned them and later spoke of them as a mistake. In the following centuries, many lost their faith in her, but others fanatically awaited for her return. Like in the case of mankind, Jasmine assumed a shape similar to that of her zealots.

Possessing Cordelia

In season two, Angel attempts to give Darla, who is dying at the time, a second chance at life by passing a series of trials. However, unbeknownst to Angel, Darla can't use the new second chance because she is already on her second life, and Jasmine claims that she was able to use the life that Angel earned to create Connor after he had sex with Darla (who had been re-sired by Drusilla at the behest of Wolfram & Hart). Following the birth of Connor, Jasmine is able to maneuver Cordelia with Skip's assistance into becoming part-demon and later ascending into the realm of the Powers. Once in the realm of the Powers, Cordelia finds herself consumed with boredom. Cordelia eventually elects to give up her godhood and return to Earth in her previous half-demon form, but Jasmine uses this interdimensional trip to "piggy-back" into our dimension by possessing Cordelia. However, the Powers had in place a safeguard for this type of travel.

Upon arrival back on Earth, Cordelia finds herself with a severe case of amnesia that locks out her experiences as Cordelia. Undaunted (and unaware of Jasmine's presence), the Angel Investigations team immediately set about restoring their friend's memory by way of a magic spell. Eventually, the team is able to restore her memory, thus unlocking Jasmine's personality instead of Cordelia's. (Though when in Cordelia's form, she acts more malevolent than when corporeal; as the story arc was altered when Charisma Carpenter became pregnant during production, Jasmine may have originally been intended to be a different type of character)

Jasmine is able to take over Cordelia and manipulate all of Cordelia's friends, who do not know that she is possessed by Jasmine. Following her return to Earth, Jasmine works to keep Angel Investigations off-balance and distracted so they won't notice or prevent her birth. First, she summons her servant, the unstoppable Beast, and has him create a rain of fire and block out the Sun all over Los Angeles through a spell that will eventually cover the entire Earth. Then, having cast a powerful spell to erase all references to the Beast (and herself) in memory and literature in this reality, she uses the possessed Cordelia to convince the team to release Angelus, the only one who has memories of the Beast. Following that, she steals the Muo-Ping (a sacred glass jar that contained Angel's soul), fakes a replacement way of re-ensouling Angel, and casts a spell that confuses Lorne's abilities so Angelus will be "accidentally" released by pretending to still be Angel. She also murders Lilah Morgan and has the Beast completely obliterate every presence of Wolfram & Hart in Los Angeles.

In the meantime and with the champions distracted, Jasmine remains inside of Cordelia and seduces Connor, whose primary purpose had been to be the father of her new body. She also magically battles Willow Rosenberg (and loses as she is distracted) in order to attempt to stop the soul within the Muo-Ping from being returned (and Angelus being changed back to Angel). By the end of the crisis, Cordelia has already been impregnated by the fast-gestating new body of Jasmine.

Jasmine finally blows her cover during Lorne's attempt to regain his powers. During a secret ritual where Lorne is expected to be alone, "Cordelia" arrives with a large knife to kill him. It is really a trap set by the AI team who had all realized that Cordelia was possessed, but she is saved by Connor. With his further assistance (including the kidnapping of an innocent virgin for sacrifice), Jasmine is able to give birth (while possessing Cordelia) to her new body.
