Normally when a major villain's mooks are getting slaughtered all around them by the heroes, the villain slinks off through a secret escape tunnel, or hightails it to an escape vehicle of some sort (possibly carrying their fluffy white cat with the diamond-studded collar with them).

For a change, how about having the villain enjoying the carnage? Revelling in the havoc and mayhem. Sitting back and just wallowing in the bloodshed.

Try to insinuate that they're not panicked for a very good reason.
