>>43534857>>43534857It's basically May's personality, at times she had anger outbursts very similar to Misty's and she had a huge temper when things didn't go her way. Not to mention most of her arc is bickering with her rivals Drew/Harley, with her brother Max, or with Ash at times.
Notice how all the more recent female characters never explode in anger anymore, even when they're upset. Dawn was really the last one to do it at times and even then it was rare.
