This artificial intelligence was regarded by Kurros as one with "the mind of a mathematician and the soul of an artist," adding that "I'm afraid he'd much rather be modelling a fractal sculpture than analyzing the data of our latest astronomical scan."
Upon meeting Seven of Nine, this artificial intelligence wished to speak to her about her bionetic technology. Seven allowed it, and the two interfaced via direct telepathic communication, at which point he requested information about integrating organic components into its own technology, and Seven complied by giving him "some pointers."
Later, when Seven of Nine rejected their request for her to join the "Think Tank", this artificial intelligence provided them with information, stating that "our calculations indicate a 96% chance the Borg will still be ours." (VOY: "Think Tank")
The jellyfish-like lifeform was a female coelenterate lifeform member of the "Think Tank". She was an expert on temporal physics, and was regarded by Kurros as one of the most gifted members of their group.
When Kathryn Janeway and Seven of Nine first encountered her, they assumed that she was being studied by the "Think Tank" members, but was informed by Kurros, that in fact, she was studying them. According to Kurros, she found them "interesting."
Later, when Seven of Nine rejected their request for her to join the "Think Tank", this individual suggested their best course of action was for them to "let the scenario continue." (VOY: "Think Tank")
