If you don't want to participate, it's alright. You have all rights to say no. If you want to participate, but not show your real voice, maybe try speaking in an accent! Spottedleaf would talk in a British accent, and maybe Whitestorm in an Australian accent! The possibilities are ENDLESS!!!
I gave Bluestar a light country accent. I was going to give her a Russian accent, but I cant do Russian. Also, you have to go inside the project to her my auditions
