Jarella

Jarella first appears in Marvel's Incredible Hulk stories as the princess of the sub‑atomic world of K'ai. In narrative terms she becomes linked to the Hulk when the Hulk is shrunk or transported to K'ai, participating in storylines in which she defends her city from invaders (warthos, Visus, Psyklop), calls on her people's sorcerers for aid, and forms a deep romantic bond with the Hulk/Bruce Banner. Key published story events include her introduction in The Incredible Hulk #140 (and subsequent early 1970s storylines), conflict with the warlord Visus and foes such as Psyklop, and a widely noted death in The Incredible Hulk (vol. 2) #205 (November 1976), after which Mar‑Vell returns her body to K'ai for burial; writer Len Wein later commented that he intended the apparent death to be part of a metamorphosis into a higher power.

Sources describe Jarella as a member of K'ai's humanoid populace, who are green‑skinned and for the most part blonde‑haired; she is repeatedly characterized as noble, beautiful and athletic. She is called a 'perfect noble princess' in critical commentary and is noted as an equestrian who rides native horse‑like and winged serpent creatures of K'ai. No canonical, detailed costume or facial-feature inventory is provided in the supplied textual sources.

In her baseline state Jarella possessed the strength of a normal human and was athletically trained: she is described as a skilled sword‑fighter, strategist and equestrian. She exercises political authority (exiling Visus) and can call upon K'ai's sorcerers to perform spells that affect language and mental control (for example, a spell that enabled the Hulk to learn K'ai's language and allowed Bruce Banner's personality to control the Hulk's body). Following her death in certain storylines, sources state she was 'empowered by all the positive feelings that Hulk had felt towards her' and temporarily gained superhuman strength exceeding the Hulk's regular state; this post‑mortem empowerment is presented as a narrative development rather than a routine, repeatable power.
