In order to apply the "shell", players go to the "Fusion" tab in the Equipment section. Clicking on the "Change Fusion Item" will bring up a tab that allows players to move their fusion items in possession to the "fusion closet", where the items are equiped as the "shell". Fused items can be unequiped at any time. Transforming armor/acessories into fusion items requires one Fusion Coupon which can be bought with cash from the Shop/Academy Tab or 15 Hero's Bullions for one in the Hero Shop.
