Wait until he debuts, lets all complain about that name because surely it's going to be dreadful too...
Also, in this age where we have generic ass names like "Cody Rhodes", "Justin Gabriel", and even "Daniel Bryan" running around, don't tell me WWE wouldn't be fine with "Chris Hero". And I wouldn't blame him because nobody in their right mind would think "Kassius Ohno" > "Chris Hero"
Think part of why Ryback got over so quickly as somebody different was his awkward name, it helped him stand out. "El Generico" could do the same thing, plus it'll make the kiddies laugh.
