Nope, they are pretty popular still and new figures are out for them, though maybe not as popular as say, Ben 10 or Hannah Montana! They are kind of like the Yu-Gi-Oh! cards (same principle, based on a Japanese animated cartoon – ie. anime – only it doesn’t use cards). I guess sort of a hybrid of Yu-Gi-Oh! and Pokemon in a way 😆
Check Walmart, Target, Toys R Us, or Kay-Bee Toys for the toys. They should have them. If you don’t see them, I’d ask a clerk.
