The Mikkians were a species of brightly colored humanoids. Members had four limbs: two legs, and two arms with five-fingered hands, including an opposable thumb. Their heads had two forward-facing eyes, whose irises could be blue.

However, the Mikkians’ most distinctive feature were their motile head-tendrils, the number, form, and pattern varying between individuals. These head-tendrils primarily served as sensory organs, particularly detecting sound as a replacement for an ear common in other species. However, some Mikkians, such as Zeen Mrala, possessed ears in addition to head-tendrils.

Mikkian head-tendrils also could detect other information, such as humidity, temperature, magnetic direction, and radiation. This radiation detection was sensitive enough that Mikkians could “see” light and dark, although their eyes were still their primary visual organs.

Mikkians’ skin ranged in pigmentation from bright yellows and greens to reds with blue highlights and pinks. Coloration varied greatly even among closely related individuals. For example, even twins, such as Tiplee and Tiplar, had vastly different skin pigmentations. Parents and children could also have very different colors.

Mikkians placed kinship and integrity above all. In fact, their honesty could come across as blunt or even rude to other sentients. Conversely, Mikkians often had trouble adjusting to the more flexible views of other races. Their complex code of honor encompassed all things in life, with a particular insistance on matters of warfare. Although they respected warrior traditions, the Mikkians nevertheless valued discipline and honor over victory or physical might.

Their native language was a melodic, flowing tongue made up of several ancient dialects. Although most Mikkians were proud of their language, they had no qualms about learning Galactic Basic Standard.

Different religious traditions existed among the Mikkians, but belief in the Force played a central role in all of them. As such, when the Jedi Order were branded as traitors by the Galactic Empire, Mikkians were quick to question the Empire’s reasoning.

In Mikkian society, their head-tendrils had important cultural significance, and as such tendril-reading was used by Mikkian mystics to predict their future. Every facet of the head-tendril contributed to that meaning.
