Kakra

K43, referred to as Kakra by the indigeonous population's elders in their native tongue, was a tectonically unstable volcanic planet located in an area of Wild Space, within the Expansion Region. Thought to be uninhabited, K43 was home to the Kakrans, a species of sentient rock-based lifeforms. The Alliance to Restore the Republic sent Chewbacca and C-3PO to the planet with proton detonators, planning to lure Imperial Star Destroyers to K43 and exploit the planet's instability in order to destroy it. However, upon their arrival, the rebels discovered that K43 was not uninhabited.

During a battle between Rebel forces and the Imperial Star Destroyers the planet began to break apart before revealing it was actually a shell around a giant version of the Kakran species. The large Kakran proceeded to destroy the orbiting Star Destroyers allowing the Rebels to escape.

Kakra first appeared in Star Wars (2015) 68, a comic written by Greg Pak, illustrated by Phil Noto, and published by Marvel Comics on July 10, 2019.

The Amazon listing for the Star Wars series' twelfth volume mentioned Chewbacca and C-3PO encountering a secret droid civilization on an unstable planet, which was later removed. However, in Star Wars 68, K43 is inhabited by a species of rock people, rather than droids. The solicitation for Star Wars (2015) 70 identified the planet as "Planet K43," but its name was only given as K43 in the comic itself.
