These are Peltier Supermen, your yellow and blue is a Peltier Cub scout, all 4 of the ones I have pictured above are Akro Supermen. Red is needed to qualify it as a Superman, whether Peltier or Akro.
This Peltier Cub scout, though a hint more yellow than yours, they made these by the hundreds of thousands so the colors may vary a bit, still a Peltier Cub Scout.
