The Thunder Morphers are the transformation device of of the Thunder Rangers, activated with the call, "Thunder Storm, Ranger Form". They were given to Blake and Hunter by Thunder Ninja Academy Sensei Omino, during an attack on the Thunder Ninja Academy, but they were unable to use them before being captured.
The Crimson and Navy Thunder Morphers were modeled after a Hercules Beetle and a Stag Beetle respectively.
The Thunder Rangers were robbed of their powers by Lothor, with their morphers being cast into the Abyss of Evil. Nearly a year later, the Ninja Rangers reclaimed, and shortly after, permanently lost their morphing powers in a final battle against him (alongside the Dino Thunder Rangers).
