Kragon is the third of three "True Dark Spectrobes", a and the final boss in Spectrobes: Beyond the Portals. It is similar in appearance to Dolgan and Dolgon, which are battled prior to it. According to Krux, Kragon and its counterparts were created after years of research "in the dark, distant corners of time and space", created as a mix of Krawl and Spectrobe to be the "ultimate creature[s]". It does not move, nor does it attack, but it cannot be damaged by any attacks. However, after a while of attacking, the Ultimate Form within the Flame Geo, Tindera, emerges and defeats Kragon.
