Were there any trainer sprites that have gotten their sprites changed due to some reason?

Question

So what I am saying in the past, there obviously have been some sprites changed of course because some Pokemon have gotten some changes before like Jynx. Please state what the sprites were before, how Pokemon changed them, and what they look like now.

Are you only interested in changes post-release, or would revisions during development count as well? I am aware that there have been changes to trainer sprites due to things like unintentionally awkward gestures but they were generally sent back for editing before release.

Aren't there a couple that were changed for European and North American releases for being 'too sexual' or specific gestures?
