According to the 4Kids continuity, the Shadow Fire is the source of Darkar's magic and is the ethical antithesis of Bloom's Dragon Fire being considered an evil power (while the Water Stars are an elemental opposite to the Dragon Fire and are neutral, neither good nor evil). It is indirectly the main antagonist. Years ago, an unnamed man went to Shadowhaunt seeking to control it, but instead got controlled by it and was reborn as the Shadow Phoenix.
