Rey Mysterio needs to interrupt a random Hunico & Sin Cara match on Raw and grab the mic and be like...
"yo this is what they want from us, they want us fighting each other. We la familia, we all look alike breh and the man is holding us back, They made you Sin Cara a laughing stock here in America where is you were just as big as John Cena in Mexico. They even tried to push me out of this company for all ive done for them for over a decade, well ive had it up to here with what you people want and all this charity kid crap and if you guys want to join me, join me"
Heel Rey is born
he can come out wearing some black leather mask with a chopper suit and make Sin Cara unmask and say he will lead them to a big future in WWE, Rey's whole thing is he wants Mexican heritage to live on now that he is old and he doesnt want HHH and the powers that be to hold him back
hell, they can even turn
"The Real Americans" face to battle them on some
"Nation vs DX" old school shyt
this would be a good way to resurrect Rey's

recent career, sample to see how the kids react when one of their heroes turns heel (to see if it will help Cena later on) and he can be a mentor to my nikka Hunico, Sin Cara, and bring in the big man, Hernandez
