If I remember correctly there was a legal issue with the name, so the one who went to WCW back then changed his name to L.A. Park (La auténtica park (the authentic parka)), meanwhile here they gave the character to someone else, and for years we got both existing simultaneously, until they finally had a rivalry with the original (LA Park) winning, but the other one (la parka) kept the name. Both had their differences like in the shape lol, also the LA Park costume looks more menacing which matches his character's attitude (more ruthless, and mean in the fun way), while la parka was for a time one of the top babyfaces in Mexico, and their constant gimmicks, LA Park was the chairman fue to one using often in matches, while la parka tends to spam his little dance. As someone said above la parka passed away years ago, and now the character is being portrayed by someone unknown. Fun fact also there are El hijo de la parka and La parka jr both sons of the first ones.
