One flaw to the Team Rocket uniforms produced after the organization broke up was that they were no longer expensive, protective gear. They were now cheaply purchased polyester blend tracksuits that, unfortunately, went up like kindling when hit by flames. (...Team Rocket rarely trained fire types to begin with.)

"OH ARCEUS NO!" the guy yelled as his clothes went up like gas soaked newspaper.

Sonny sprinted out the doors, changing into a Snorlax on the way and smashing the door frame with his heft. He unleashed a Blizzard attack directly at the guy, icy winds and hail the size of golf balls slamming into the poor unfortunate and pinning him to the grass under a sheet of frost.

....so he was pretty much naked, singed and locked to the ground by a slab of ice infused with wood chips from Oak's broken building. This was not Team Rocket's finest hour.
