Well I'm certain the Donald Duck and Goofy would against a Zanaffar about as long as it takes for the Zanaffar to close his mouth... while they apparently do pretty well against the heartless.

Heartless are also apparently mindless, so a Zanaffar could outwit them easily. It also says magic can hurt/kill them, so I'd assume that they aren't immune to a Zanaffars laser breath.
