This paper toy is Blue Ranger, a title given to a character in every Power Rangers TV series, the papercraft created by Bruno Vilardi. While the original Blue Ranger was a serious team member and represented "the smart one", subsequent Blue Rangers have been pushed to the position of "comic relief." Blue Rangers are generally male, however recent seasons have had female Blue Rangers. So far, female Blue Rangers wear a lighter shade of blue than their male counterparts, although Cestro as the Blue Aquitian Ranger also wore a lighter shade of blue similar to that of the female Blue Rangers. There are also Pink Ranger and Yellow Ranger Paper Toys on the site.
In Power Rangers in Space, Power Rangers Lost Galaxy, Power Rangers Lightspeed Rescue, Power Rangers S.P.D., and Power Rangers Samurai the Blue Ranger serves as second in command.
Also, it is one of the 3 colors to be present in every season alongside red and yellow, but the only color to never change characters mid-season. [Source: wikia]
