Become Ash Ketchum's most loyal Pokemon and wear this Pokemon Pikachu Kids Costume this Halloween. Pikachu is a yellow electric Pokemon that can be both adorable and powerful. For a cuddly, rodent-like creature, Pikachu packs quite the thunder punch. The outfit features a yellow dress with a pleated skirt and lightning bolt details, as well as a lightning bolt tail, a pair of fingerless yellow glovelets, a pair of matching yellow leg pieces, and a Pikachu character hat. You can also accessorize this costume by checking out some of the items that are sold separately on our site. Some great ideas would be a face paint makeup kit or a bag to hold all of your Halloween candy. Have a friend dress up as Ash to make this a group outfit.
