The Brachio Morpher is the personal morpher device used Tommy Oliver to transform into the Black Dino Thunder Ranger. It is powered by the Black Dino Gem. It is activated when Dr. Oliver calls out "Dino Thunder, Power Up!" then inserts and turns a special key. This is the morpher of the Black Ranger. Tommy’s morphing device was created by Hayley when Tommy discovered the fourth Dino Gem, "just in case".
