Pegasus Saber is formed from the 4-Unit Combination of the Skies of the Sabers (a subsidiary group of the Brave Warriors), including Sky Saber (Jumbo Saber, Shuttle Saber, Jet Saber) and Hawk Saber.
The Sabers' final trump card, Pegasus Saber exceeds Sky Saber in terms of speed, power and equipment.
During Episode 19, after Seiji Takasugi thought of a plan to defeat Butcho's monster by getting it into outer space, the Sabers combined into Pegasus Saber and used his Saber Arrow as a grappling hook to tow the monster out of Earth. He later joined in combat against Butcho's spaceship.
