Shadow Chromite is a Villian of Power Rangers Turbo.
He had a Shadow-Morph gun, and had a detonator linked to him.
The gun-device had the power to make Shadow Rangers.
When Shadow Chromite appeared, he shot at the rangers, then the Shadow Rangers appear. The Shadow Rangers captured the then powerless rangers, ironically with their own powers.
After that was around the time Blue/Dustin arrived with Tommy. He tried to morph when Tommy realizes that, the Shadow Rangers were created as they morph. Dustin was then taken as well.
Tommy then regroups at the command center. Thinking about the Shadow Rangers, he figures out that Light is thier Power Source, and he needs to use Shadows/darkness to defeat them.
Morphing at the Command Center away from Shadow Chromite, he then starts to look for the others using Dustin/Blue's Tracking device.
He defeats Green, Blue and Yellow Shadow Rangers, by knocking them into shadows.
Then Tommy rescued the other Turbo Rangers from the cave, after defeating the Pink Shadow Ranger guard.
They faced Shadow Chromite who like Shadow Rangers, was made of light. The Turbo Megazord then blocked Shadow Chromite's light source.
This made him dissolve and it destroyed the detonator with him.
Shadow Chromite was the first of the chromites, as a generic version was made by General Havok, but they lacked speech.
His life was linked to a detonator, like most of Divatox's Soldiers. His detonator was in a leaking paint can. Despite being a chromite, he had speech, and a personality.
