Just posting name isn't enough to nominate, read the rules (picture, description, who's in).

For what it's worth, I had intended to flush-out the nominations later, but tiredness claimed me too soon after I got home from work, and someone else beat me to it.

36. Mighty Morphin Power Rangers

Each of the Power Rangers seasons, or incarnations, centers around a group of people, often teenagers (age of actors actually varies from 18 to 23 years old), that gain super powers to fight various villains, ranging from demons to witches to aliens. Throughout the series, the Power Rangers learn the importance of teamwork and perseverance as they battle progressively harder to defeat villains.
Often, before a monster is defeated, a monster will grow into gigantic proportions, forcing the Power Rangers to use gigantic (bio)mechanical machines known as Zords. In many cases, these Zords can be combined to form a more advanced (and humanlike) machine, a Megazord.
