After several battles against the Wind Rangers, the Thunder Rangers finally discovered the truth in the Cavern of Spirits, where the spirits of their deceased parents appeared to them. Their parents told them that it was actually Lothor who killed them. Furious at this deception, the Thunder Rangers turned on Lothor, and joined the Wind Rangers. Blake and Hunter are top level motocrossers, and frequently practice with Dustin, who helped them get jobs at Storm Chargers as stock boys.
Blake lost his powers in the final battle against Lothor, who stole all of the Ranger powers for himself before being defeated. After graduating from Thunder Ninja Academy, Blaek went on to become a professional motocross racer.
When he battled the Wind Rangers, Blake found his attraction to Tori conflicting with his mission of vengeance. He ultimately did use her to gain access to Ninja Ops, but not without feeling remorse. As a teammate, he actively pursues his fellow Blue Ranger, sometimes to the chagrin of his brother. As the Navy Thunder Ranger, Blake harnesses the power of thunder, and pilots the Navy Beetlezord.
