<P> When "morphed," the rangers become powerful superheroes wearing color - coded skin - tight spandex suits and helmets with opaque visors; identical except in individual rangers' color and helmet design . Morphed Rangers generally possess enhanced strength, durability, agility and combat prowess . Some possess superhuman or psychic abilities such as super-speed, element manipulation, extra-sensory perception or invisibility . In addition, each individual ranger has a unique weapon, as well as common weaponry used for ground fighting . When enemies grow to incredible size (as nearly all do), Rangers utilize individual Zords that combine into a larger Megazord . </P> <P> Rangers teams operate in teams of five or three, with more Rangers joining the team later . Each team of Rangers, with a few exceptions, obeys a general set of conventions, outlined at the beginning of Mighty Morphin and implied by mentors throughout many of the other series: Power Rangers may not use their Ranger powers for personal gain or for escalating a fight (unless the enemy does so), nor may the Power Rangers disclose their identities to the general public . The penalty for disobeying these rules, in Mighty Morphin Power Rangers, is the loss of their power . </P> <P> As in Super Sentai, the color palette of each Power Rangers team changes every series . Only Red and Blue appear in every Ranger team, while a Yellow Ranger has been present in every season except Power Rangers Dino Charge . Other colors and designations also appear throughout the series . A Rangers' color designation also influences their wardrobe throughout the series: civilian clothing often matches Ranger color . </P> <Table> <Tr> <Td> </Td> <Td> This section needs expansion .
