Me and a few friends are all going in cosplay. Anyone else going, and if so, who as?

Me- Izaya Orihara and Walker Yumasaki
Friend1- Erika Karisawa/Kingdom Hearts Organization member
Friend2- Shizuo Heiwajima/Aku (Samurai Jack)

then like another group of 5 as Avatar: The Last Airbender characters. owo
