Pōna is a minor character who appears in the original video animation adaptation of Space Family Carlvinson. She is an alien whose face and body are fused into a single continuous form, and her speech and mannerisms resemble those of an elderly woman.

Near the end of the story, a spacecraft arrives on the planet Anika, and the family believes it has come to take the orphaned human girl Corona back to her home world. It is eventually revealed that the ship was not sent by Corona's own people. Pōna is an alien who had been searching for lost children to raise as her own, and she hoped to take Corona with her. When her intention becomes clear, Corona refuses to go, saying that she likes staying with her family, and waves goodbye as Pōna departs.

Pōna's motivation is rooted in her desire to adopt and care for children who have no family. Her brief appearance serves as a final test of the bond between Corona and the alien family that raised her, and her departure without Corona confirms that the family will remain together. Because her role is limited to this concluding portion of the story, no further background, personal history, development, or abilities are described in the available material.
