10 Reasons WWE Will NEVER Be Able To Replace Rey Mysterio

10. Rey Made It Incredibly Easy For A Grown Man To Sell Merchandise Aimed At Children (And Not Make It Terrible TV)

At 5'2", sporting colorful gear and fanciful masks, Rey Mysterio appealed to the children's demographic WWE so desperately wants to court without having to change anything at all about his typical in-ring presentation. No matter what Rey was doing in the ring, he was still naturally child-sized and presented himself in a manner that directly appealed to small children (of course including him stopping to greet every child wearing his mask as he walked down the aisle to the ring). For say, John Cena to do something similar, he's had to change key parts of his presentation and look more like a grown adult-sized 13-year old playing pickup basketball than a man who battles in the ring.
