Jarella was the princess of the sub-atomic world of K'ai. Although outwardly primitive, her world has remnants of long-forgotten high technology and sorcery. Its people are green-skinned and for the most part blonde haired, but otherwise humanoid.
Jarella's city is threatened by a number of menaces ranging from attacks by the gigantic warthos (warthog-like beasts) to the armies of the Warlord Visus. The Hulk appears in K'ai during an attack of the warthos and drives the huge monsters away. The people come out to greet him, and the Hulk is especially taken with the lovely and gentle Jarella. She leads him into the city and calls on her sorcerers to help the Hulk learn their language. The spell succeeds and also allows the human personality of Bruce Banner to emerge in the Hulk's body. The Hulk and Jarella fall in love and she proclaims him her husband. After Visus attempts to assassinate Jarella she exiles him from the city. However, Psyklop snatches the Hulk away from K'ai.
Jarella is soon transported to Earth by the Pantheon of Sorcerers (Torla, Holi, Moli; also known as the Sorcerer's Triad) to retrieve the Hulk. This act inadvertently causes solar storms; she battles Fialin and then returns to K'ai. She loses another war a
gainst Visi and is taken captive. The Hulk returns to K'ai, and Jarella and Hulk defeat Visis and the assassin Krylar.
Jarella accepts the Hulk unconditionally. She comes to know Bruce Banner's mind in the Hulk's body but is equally accepting of the Hulk personality, or Banner's body.
Alongside the Hulk, Jarella battles Psyklop once more. Hulk and Jarella are then returned to Earth by Doc Samson. During a battle between the Hulk and Crypto-Man in an unnamed town in New Mexico, Jarella saves a child from a collapsing wall, but is crushed to death herself. The Hulk takes Jarella's body to the Gamma Base, but the doctors are unable to revive her. The Hulk rampages in search for his friend, the magician Doctor Strange, but the latter is also unable to restore her, and he finally accepts that Jarella is dead, while being comforted by the Valkyrie. Captain Mar-Vell shrinks the Hulk so that he can return Jarella's body to K'ai for a proper burial. After being put to rest, her spirit takes farewell by creating a single green flower.
During the Chaos War, queen Jarella is revived to assist the Hulk in fighting Abomination, a Zom-possessed Doctor Stran
ge, and the forces of Amatsu-Mikaboshi. After the Hulk and allies were nearly defeated by his undead father Brian Banner (empowered into the Devil Hulk through all the fear and rage that Hulk felt towards him over the years), she saves her husband and helps to defeat Brian. Bruce's similarly returned mother tells him that although she disliked his other wife Red She-Hulk, she definitely likes Jarella yet both of them soon will have to leave again.
Powers and abilities[edit][]
Jarella was an athletic woman with the strength of a normal human but was a skilled swordswoman, strategist and equestrian. She would ride horse-like steeds and winged serpent-creatures indigenous to K'ai.
After her death, she was empowered by all the positive feelings that Hulk had felt towards her, and as her beloved draws his power from emotions, she apparently gained superhuman physical prowess even exceeding his own regular state.
