A lot of games are compatible with any amiibo, but you'll just a generic goodie. Like you could scan the Bayonetta amiibo into Breath of the Wild and get some random items, or you could scan it into Hey PIkmin and get about 10 Sparklium. But yeah, it's really designed just for Smash Bros.
Although I read that if you scan the Bayonetta in the new Kirby game, you'll be able to play as her. Just joking! I just made up that last part to see if you were paying attention! :)
