The Beast Morpher Rangers are a government-funded team formed by Grid Battleforce from Morph-X combined with animal DNA.
Blaze and Roxy were the original candidates for the Red and Yellow Rangers until Evox corrupted the morphing process and infected their bodies; producing clones who became his loyal Avatars while the real ones were rendered comatose.
[2] Due to Evox's corruption, Ravi will overheat and become enraged whenever he overuses his powers enough to attack friend and foe alike.
Being a genius, Nate is a quick thinker in situations that require it; such as when he gave Devon, Ravi, and Zoey their powers to protect the Morphin Grid.
[2] He is also the unwitting creator of Evox when he experimented with Morph-X, snake DNA, and a Cell Shift morpher infected with the Venjix virus.
[17] When he was kidnapped by the Avatars and forced to build a robot body for Evox, Nate was able to subvert the plot by fusing himself with mantis DNA, which allows him to use martial arts, and become the Gold Beast Morpher Ranger.
[9][10][11][12][13] Steel is a stag beetle/scarab beetle-like android whom Nate built after he was captured by the Avatars and forced to build a robot body for Evox.
[18] During the Rangers' final battle with Evox, Steel sacrificed himself to stop him, but the Morphin Grid later revived him as a human, who became an actor following the virus' defeat.
While becoming the Red Ranger, Evox corrupted the process; putting Blaze into a coma and creating an evil avatar based on him that continued his rivalry with Devon.
[2] When his avatar is destroyed, Blaze comes out of his coma and makes amends with Devon; becoming fast friends before returning to his karate instructor job.
While becoming the Yellow Ranger, Evox corrupts the process; putting Roxy in a coma and creating an evil avatar based on her.
[2] When her avatar is destroyed, Roxy comes out of her coma and helps the Rangers foil one of Evox's plans using her evil counterpart's knowledge.
After Nate mixed Morph-X and snake DNA with the morpher, Venjix used its codes to escape, take the name Evox, and assume a king cobra-like form.
[17] In doing so, Evox creates evil avatar clones of Blaze and Roxy, puts the real ones into comas, and corrupts the Beast Morpher Rangers' animal DNA.
[2] However, he and his Avatars are sent to the Cyber Dimension, where they form an alliance with Scrozzle to obtain enough Morph-X to send Evox back to Coral Harbor.
[19] Ever since, Evox secretly works to collect Morph-X once more to continue his plans and undermine the Rangers as Mayor Daniels while maintaining control over his host.
[20][21] Following a failed attempt to build a Chimera Zord,[32] Evox allows himself to be captured by Grid Battleforce so he can obtain the morpher he hid within and download his original codes from it, restoring himself to his full power without Morph-X and granting himself the ability to rebuild destroyed Robotrons.
[17][6] In season two, Scrozzle used the Dino Charge Rangers' Energems and a geode to create the dinosaur-themed Chimera Zord for Evox.
[2][3] After a series of schemes and plots,[4][18][27][7] he and Cybervillain Roxy succeed in stealing a Morph-X Tower so Scrozzle can use it to build Evox a robot body and send him back to Coral Harbor.
[15] When the Rangers storm the Cyber Dimension to destroy the tower, Blaze pilots a Megazord Scrozzle built to stop them, only to be defeated by Devon in the Racer Zord.
While Roxy was becoming the Yellow Beast Morpher Ranger, Evox corrupts the process; placing her in a coma and creating an evil Avatar based on her to serve her.
When Evox and the Cybervillains arrive in the Cyber Dimension, Scrozzle reluctantly forms an alliance with them, lending them his gadgetry skills, Tronics, Robotrons, and Gigadrones.
[33] After the Cybervillains successfully steal a Morph-X Tower, Scrozzle begins construction on a robot body for Evox before preparing to teleport him back to the real world.
One year later, he is found by Colonel Mason Truman, Betty, and Ben, and remanded to Grid Battleforce's holding cells.
After using several Fury Cells on himself, he became more evil than his creator and turned on him, forcing Scrozzle to take refuge in the Cyber Dimension.
[3][36] After eventually finding him to take the remaining Fury Cells and defeating the Cybervillains, Evox recruits Vargoyle into his ranks and offers a reward if he proves himself against the Rangers.
[36] Vargoyle continues to prove himself to Evox by easily defeating the Rangers in a second fight and building a weapon from a blueprint he stole from the Cybervillains for his master plan.
[25][28] To maintain his usefulness to Evox, Robo-Blaze upgrades himself with a large amount of Morph-X, gaining enhanced strength and speed.
[25] To maintain her usefulness to Evox, Robo-Roxy upgrades herself with flower DNA, gaining a left arm-mounted pollen cannon.
While fighting the Rangers in her new form, she uses the full power of the dinosaur DNA to enlarge herself, but is permanently destroyed by the Beast-X King Ultrazord.
