Vegas Hero Convention

The Vegas Hero Convention (VHC) is an annual event attended by heroes, other supers, and fans. Many thousands of people attend - the record year was one hundred and fifty thousand. Class S heroes tend not to go and some groups - such as the Sentinels - only send a single representative.
Current head of the organizing committee is director Carolyn Ritter.

Show spoiler

The convention is in fact secretly organized by Destruction Corps and Carolyn Ritter is really Commodore Catastrophe. Now that this has been discovered, it's not known if the convention will continue.
