Nega-Xehanort

Nega-Xehanort is the SAFA Xehanort who ended up becoming a darker and more evil variant of the original Xehanort because of the events of Kingdom Hearts III deviating from the High Council's grand design, being created by Cobra from a time spell after seeing the original Xehanort unworthy for his less-sinister new outlook.
