Minerva is a Chroma executive with a physically imposing presence and a reassuring manner. In Chroma Courtesy, she enters a clinic exam room to speak with Lawrence after his identity draws attention. Formal at first, she answers his denial with humor and then promises that Chroma will meet his medical needs for the rest of his life.
The clinic scene describes her as eight feet tall and broad, wearing tailored platinum-gray clothes and a polished chrome tie. Her warmth turns an intrusive institutional encounter into reassurance.
In the younger Pineapple Cup period, Minerva finds the runaway Crystal during a forest assessment. She arranges help from Glitterhart and leaves the unicorn to care for the child. That encounter belongs to its own era; it does not establish that Minerva personally opens the portals or provides medical treatment.
