Jaden Sentai Nejiranger
Translation: Evil Electric Squadron Twisted Ranger

Created by Dr. Hinelar from Javious' DNA, the Nejiranger were made to counter to the Megaranger. Javious did not know his energy was taken. Firstly, they imitated the rangers except for black marks on their chests and tried to frame them. Unfortunately, the Nejiranger were impatient and wanted nothing more than to kill their Megaranger counterparts. In this way, the Nejiranger were used by Hinelar not only to kill the Megarangers in suicide attacks, but also to kill Javious by slowly draining him of his life energy.
When badly damaged or enlarged, they transformed into their true monstrous forms. However, the Nejirangers' urge to kill managed to keep them from passing on, as they used Hinelar's data-card machine to regain physical form and not only resume their goal, but to try to kill Hinelar for exploiting them. But the Megaranger managed to digitize them, preserving them as Datacards in the now destroyed Hinelar City. Hinelar found the cards soon after the city was destroyed, and sent them to where no one would ever find them. They appeared from episodes 38 to 43 and episode 48.
