specific functions: navigation (April), weapons (Colt), pilot (Fireball) and the commander/tactician (Saber Rider). A highlight of nearly every episode is Ramrod's transformation from an airborne battleship into a giant fighting robot. When the Ramrod Equalizer Unit undergoes the "Challenge Phase" (usually activated by Fireball pressing a button in the center of his unit console), April calls out that Ramrod is taking over the navigational controls during the transformation. Ramrod acknowledges this while the 4 control units are shifted to new positions inside of Ramrod's head. As it completes the transformation it calls out its rallying cry in a heavy Western drawl, "Head 'em up, move 'em out...power stride, and ready to ride." The Ramrod vehicle will transform into a giant robot packing an over-sized six-shooter at the hip and appears to be wearing a cowboy hat and a cape. The battle conversion to robot form is used mainly when the Star Sheriffs encounter the Outriders' giant robots, which are known as either a Renegade or Desperado Unit. In "Maverick Quick-draw" mode, an array of assorted cannons will be deployed at Ramrod's chest, delivering the final blow to send an Outrider "Renegade Unit" back to the Vapor Zone. The Star Sheriffs sometimes refer to Ramrod's robot form as the "Big Sheriff." In the final episodes of the series, the original Ramrod was dismantled as part of a peace treaty brokered between the Outriders and Cavalry Command. However, when the Outriders broke the treaty by attempting to invade the New Frontier dimension, Cavalry Command issued the Star Sheriffs a more powerful version of Ramrod known as "Ramrod 2" with double the power of the original. Ramrod 2's Challenge Phase transformation was the same as the original Ramrod, only April now said "Ramrod 2 will now take navigational control." Ramrod was named Bismarck in the Japanese version, hence the series' name Sei Jūshi Bismarck. The Americanized name for the battleship possibly originates from a cowboy slang referring to the person-in-charge of an outfit, the leader of the pack, or the person who gets the job done. The Ramrod Equalizer Unit Challenge Phase is essentially the sequence in which Saber Rider And The Star Sheriffs becomes similar to a "monster-fighter (kaiju) series;" otherwise the series, in American form, is mainly Western-oriented.
