Please stop removing categories from character pages including the My Little Pony ones as well that fits the characters personalities (like Wrathful, Mentally Ill, etc.) and leave them as they are. You can't have everything your own way all the time.
Also, some MLP characters like Twilight and Pinkie Pie ACTUALLY do have some mentally ill traits and have moments of being wrafthul from what I've actually remembered. (I even remembered Twilight Sparkle becoming mentally insane in one episode and Pinkie Pie becoming mentally insane in two of the episodes.)
