User blog comment:Florence100 the Sylveon/Two Future W.I.Ps...might not be done?/@comment-3495717-20130821231451

This is a way to get a character to stay the way it is. I'm sure looking into characters like Soul Ninja MK2 that house several different characters is a starting point. Hiperhazz's Kyurem also changes its appearance without reverting back, so that'd be another good one to look into.
