Kallisto

Kallisto is a human who was raised by the Gronks and assimilated to a large degree into Gronk society. Kallisto purposefully obfuscated communications between the humans and the Gronks at [presumably] the beginning of heavy conflict on Earth in order to ensure the continuation of the war.

Appearance

Kallisto wears clothing with dramatically widened shoulders and sleeves, which stand in stark contrast with their slight build. This is true even though they often take on the role of communications officer and psionic scout, stationed in the thin corridors on the outside of their Gronk ship.

Personality

Kallisto is a germaphobe (or believed to be one by Connie)

Kallisto is honest about what they believe in or what they want

Kallisto is pragmatic

Trivia

• David Bowie was offered the role of Kallisto
• When asked about Kallisto's costume design, the designer revealed that "the guiding light of Kallisto's appearance is that their actual body doesn't take up that much space, but their outfit is supposed to take up horizontal space. Sort of like forcing social distancing, out of respect for Gronk culture."
• Part of Kallisto's theme is a countermelody to the Gronk/Nomalis leitmotif.
