Twenty-One originally appeared as literally "Twenty + One". Most fans argued that it wasn't her actual design, which proved to be correct. Twenty-One wears camping luggage and a green Tyrolean hat with three rainbow coloured "feathers", because she is 3x7. She wears a stepmask because she is the 6th step squad, and two boots, apricot and red and white socks. She can also be seen holding a walking stick.
