Reldnahc Notsew Naitsirhc is the evil opposite incarnation of the True and Honest "Christopher" Christian "Ricardo" Weston Chandler aka "Chris-Chan", as well as being the son of Giovanni, leader of Team Rocket. Just as Chris himself can turn into Chris-Chan Sonichu with the power of his Sonichu medallion, Naitsirhc uses the evil powers of his black Sonichu medallion to turn into the insidious form of Reldnahc Ha-Taque. He has his own variation of Chris' all-powerful Curse-Ye-Ha-Me-Ha attack, which he calls Quee-Fee-Mae-Mo-Bo-Bo.
