Billy Cranston, the Blue Ranger, piloted the Triceratops Dinozord. Forming the left leg, it could shoot laser shots from a twin cannon (its tail) as well as fire chain-link power cables out of its horns to subdue opponents. The Triceratops remained in the Desert while not in use.
When it was decomissioned, it was reformatted into the Triceratops Unicorn Thunderzord, so it aided Billy in a new form.
