knights and the have powers,also how the story developes like the
power rangers.The face a different bad guy every show.They also have
different weapons and skills.all i remember is this guy wearing blue
he had a mace.I think there were five or four of them.I just want to
remember the show i watched it when i was a kid and loved it!
