I would like to say first this is unlike Character of the week.This is added every once in a while after we get a winner and characters make it to different rounds and so on just so this isn't deleted.It gives people something to do every couple of days and to see if there character wins.This has failed before but since theres more members and more coming this may get popular.There will be 24 characters 4 in each battle.There will be six battles in the first round and only two people out of the four in the battles makes it out.So then theres 12 characters for round 2.Then there will three characters in each battle for 4 battles.Then there will be 8 winners.Then for round 3 there will be two people in each battle for 4 battles.Then four winners.Then for round 4 there will be two battles with 2 winners with the last round.Previous winners Shadow Mario and Ashley.
