Ken is a reptilian alien and a recurring resident of the planet Anika. A wanderer by nature, he is a nomadic figure who does not appear to have a permanent home, instead traveling across the planet and occasionally becoming involved in the daily lives and antics of the local population.

His most distinguishing physical feature is the membrane stretching between his arms and legs, which grants him the ability to fly. Ken is characterized by a mix of wisdom and more frivolous personality traits. He possesses a great deal of knowledge about the planet Anika, often acting as an informal advisor by consulting with the villagers. Despite this knowledgeable side, he also displays a lecherous and mischievous streak, exemplified by behaviors such as spying on the female character Verka while she bathes or reading erotic books.

Within the community, Ken’s background is somewhat mysterious. He is considered an ancestor by some, leading to speculation that he might be an alien who originally lived on Anika before migrating to another planet, only to later return as a wanderer. His role in the story is that of a supporting local character, contributing to the slice-of-life atmosphere of the series by interacting with the main alien family and their human child, Corona. To make a living, he is shown engaging in various jobs, traveling elsewhere to work and earning money alongside other characters like Corona. The character of Ken is known to be a parody of the character Snufkin from the Moomin series.
