Here is my Luchidor group, I borrowed some ideas from aztec culture.
The group leader is a man that goes by the name of Quauhtli, he is a very large man of Hispanic decent. He dresses in the standard luchidor mask mixed with traditional period clothing that is common to Hispanic culture. Quauhtli is an archanist, but his powers are based around physical buffs and attack powers based around movement or motion. Some of these powers can be triggered for certian conditions. Quauhtli personality is somewhat 2D, he rarely speaks and his motivation is fairly apparent when he is encountered. An interesting possibility is that the mask is Quauhtli. When someone put the mask on, it take over the personality of the wearer and over time changes the physical aspect of the wearer. Quauhtlis magic is fueled by the blood and ritual sacrafice.
Quauhtli henchman name is a slight man named Rolon. Rolon acts as the spokesman for Quauhtli, he is the one that does all the speaking, negotiation, or makes the bargins. Rolon is a very bombastic person, when he speaks he uses exagerated hand motions/gestures. He is an oily man that wears nice cloths but not to nice, middle class formal would be the best description. He wears a derby style hat and is always chomping on a cigar. When in combat situations Rolan will head for solid cover and shoot from that place, he is also not afraid to take advantage of someone that has their back turned to him. His main role in combat is to help subdue and assist Quauhtli when it is needed. Rolon loyalty is completly to Quauhtli.
The minions of Quauhtlis group is strange creatures that he calls Salvaje. They tend to be smaller then the average person, but well built. The one thing that stands out about them is they have feral aspects related to some animals. Common animal types are large preditor cats, birds of prey, snakes, and wolves. Communication with the Salvaje is about the same as the animals they take on. They are strictly close combat fighter, and are great at subduing enemy fighters. They usually do not fight to kill, but to capture.
