The S-Force capes are particularly reminiscent of Gatchaman.
The S-Force's theme music is very similar to the theme to Battle of the Planets, the Sandy Frank-created series that was the first English adaptation of Gatchaman.
The S-Force's name is a reference to G-Force, the name the Gatchaman team had in Battle of the Planets.
One of the S-Force's attacks consists of forming into a cheerleading-style pyramid and quickly whirling around, which was the Gatchaman team's signature move.
