Why cant he just go heel? all the greats did
5'3" heels that can't talk don't make much sense.
Misterio is one of the reasons why I'm such a huge fan of wrestling, so I'll always consider him one of the greatest and most influential personally, along with the fact that he was probably the main factor in why the Cruiserweight style gained such traction in the US (The Psicosis series, Halloween Havoc '97 vs. Eddy, his stuff vs. Ultimo Dragon, etc.). Hell, he was even great in his first 4 years in WWE (Watch some of that 2002 work sometime, including a candidate for greatest opening match of all time vs. Kurt Angle at SummerSlam '02). It's just that, after bulking up and the multiple knee surgeries that sapped his ability, I really want him to retire for his own health.
As for Ultimo Dragon, he inspired a whole style of wrestling with Toryumon/Dragon Gate, as well as being the reason why Chris Jericho, Lance Storm, Misterio and Psicosis (partially) really started to get on in the mid-90s with his booking of WAR. Not to mention what he did for the WCW Cruiserweight division. If you don't think Ultimo is a legend, you don't know wrestling history.
