[Animorphs] How much of a threat or nuisance were the Animorphs to the Yeerk invasion of Earth?
gpt
Minimal threat, *massive* nuisance. 

There was no chance the Animorphs alone could prevent the invasion. 

But they prove time and again they could raise it's cost. Destroying the Kandrona, for example, was a massive blow. And raising the cost, causing delays... that mattered. It cost them... 

It cost them a lot. 

But it *mattered*. They saved the planet, prevented it from dying without a fight even occurring, and you could even argue that they saved the Andalites, too, because if the Yeerks had gained full control of Earth and all it's hosts, there may have been nothing the Andalites could do to stop them.
