As much as I love the randomness, I noticed a lot of people were actually coming to this plz account daily just to use the KH plz stuff...so I decided to "organize" it for those users. Lucky you. Here's the list, alphabetized. Some are on here multiple times, 'cause they fall under more than one category.
This is far from a complete list of KH plz accounts, so feel free to comment with any I left out. 8] I haven't stumbled upon any plz accounts for Diz/Ansem the Wise, Dilan, Aeleus, Pence, or Even... :C Also, I didn't include most Final Fantasy characters or Disney characters.
And beware of spoilers!! You've been warned.
