Based at the school's Automotive Department, Ninja Steel Power Rangers' arsenal revolves around being powered by the Ninja Nexus Prism. In Power Rangers Dino Fury, the Ninja Nexus Prism were created by Morphin Masters.

Brody Romero is the exuberant, youthful, and positive 18-year-old leader of the Ninja Steel Power Rangers and the son of a ninja master named Dane Romero. Ten years prior to the events of Ninja Steel, 8-year-old Brody was captured by Galvanax after his father mysteriously vanished.
After his capture, Brody was forced to work as a slave for Galvanax. During this time, he bonded with the robotic Redbot and a shape-shifting alien named Mick Kanic while gaining an enemy in his supervisor Ripcon. In the present after overhearing Galvanax's plan to get the Ninja Steel back on Earth, he, Redbot, and Mick take the opportunity to escape with the Ninja Nexus Prism. After being forced to use the ship's trash chute as an escape, he and Redbot became separated from Mick. Upon landing, he was attacked by Korvaka, but was saved by the unexpected arrival of Sarah and Preston.
