Zanaffar are essentially creatures of endless grrowh and potential. Their hide is tougher than dragon scale, making them immune to physical attack, and as you said earlier they are immune to magic. They are capable of didcharging high powered energy beams from their mouths and growing mouths on tentacles in order to discharge more lasers as well as being quite capable of subterranean movement.

When they kill someone, they consume their minds, bodies, and souls, adding that persons skills, memories and strength to their own. What's more is that the Zanaffars seen in the show are only days old. Weeks at the most. They hadn't even scratched the surface what a Zanaffar is truly capable of and they still rendered the full might of the most powerful militaries in the world helpless.

It is even implied that if they consume a sufficient amount of knowledge in magic, particularly knowledge pertaining to high end black magic, then a Zanaffar may even find a work around to their inability to use magic.

If nipped in the bud, a Zanaffar is nothing compared to the heartless, but only a single weapon can even hurt one and that weapon doesn't really cooperate unless used by a particular bloodline (So the heartless have zero chance of harming one.) If given time, a single Zanaffar would not only be able to destroy a universe, but outright eat one.
