The Rey is awesome I used to have the yellow and purple elite but I had it about 6 years ago when I was 8 and I played with it and it broke but now I just collect figures and display them.
Rey Mysterio's actually took the name from his uncle not his father. In fact I don't think his actual father wrestled. Mysterio took the original Rey Misterio's name and gimmick but he heavily modified the mask. Some time later after Rey jr became more popular than Rey Sr.......Rey Sr started using a mask style like Rey Jr's to capitalize on Jr's popularity......I have a friend who met Rey Jr at a meet and greet and he says that Rey Jr is like 5'2'' since my friend is himself like 5'7''..
