Vinea

Vinea is a fictional planet that appears in the Yoko Tsuno graphic novel series by Roger Leloup. Its native intelligent species, the humanoid Vineans, came to Earth in the distant past due to catastrophic changes to their home planet. At the time of the graphic novels, they are in the process of returning to their planet.

The main characters of Yoko Tsuno form a close bond with some of the Vineans in the very first volume - this is especially true of Yoko and Khany - and many stories either involve the Vineans or take place on Vinea itself.

Vinean physiology

Vineans are of pale blue skin, but otherwise very closely resemble humans. No reasons are given in-universe for this extreme similarity of two species that evolved millions of years (and two galaxies) apart, and neither is this matter ever raised in the novels. However, it is understood throughout the series that Vineans cannot sunburn because their pale blue skin is more resilient than that of humans.

It is also indicated that some medicine will not have the same effect on Vineans as humans.
