From HBC, an Esplin 9466 chapter:
I searched the data banks hungrily. And one day I realized I'd found my true calling.
I came across an old Andalite saying in the computer files. <Know your friends well. Know your enemies better.>
The Andalites were our enemies now.
Yes. Know your enemy.
That was my calling. That was the way to gaining my own host. I would learn all the computer held about the magnificent, powerful creatures called Andalites.
Someday we would face the Andalites in battle. Then I would be needed.
Man, I wish that the 'present day' Visser Three was still this cunning and awesome. I mean, sure it's reasonable for him to have grown far more arrogant as he moved off up in the Yeerk Empire, but he grew way too stupid and oafish as well.
(And did anyone realize that if Ax was in his Andalite form, he shouldn't have a throat to be tightened?)
He has no mouth, but he still breaths, so as other people mentioned there's nothing wrong with him having a throat though it wouldn't necessarily have an esophagus to swallow with... but when a better example about a KASU where the lack of "mouthparts" is forgotten is when V3's thought-speak of "Enraged shouts echoed throughout the canyon" in #39, The Hidden.
I'll always like Tom's line in uh...I think #53? Yeah.
"Little brother, you've got to know by now: Wars aren't won with clean hands."
It just kind of summarizes their tension and the morality of the whole series. And it's spoken by a "bad guy". Doubleplusgood?
I totally agree with the Doubleplusgood, in making a 'bad guy' bad, fiction tends to make them less intelligent and deep-thoughted, so it's nice when they do get a chance to have a good line.

Marco: "What's the deal with you, Cassie? Half the time you're giving us crap over being too ruthless or whatever. It's always, 'Oh, is this right?' and 'Oh, should we do this?' I mean, you're Miss Morality, and then when you have a bad night you just bail on us?'
...
"Fine. You have your morals and your fine feelings and all that. We'll go off and risk our lives to save the world. You just sit here and feel righteous."
I think it got even more serious as that conversation continued. This was probably where many fans get their source of Cassie hating. Marco leaves, then:
I heard the flutter of wings and realized Tobias was gone, too.
Rachel looked hurt..
Cassie: "Rachel we can still be-"
Rachel: "No we can’t, see you’ve just said the whole world can drop dead, so long as you, Cassie, don’t end up turning into me."
A couple of my own favorite quotes:
"I’m not even average height for my age, although I make up for it by being cute, very cute. And charming. And witty. And modest."
~Marco in #5, The Predator
The Starbucks guy handed Ax a paper cup. Ax took it. He looked around to see what other people were doing. Like them, he put a lid on his cup. Then, still mimicking the others, he attempted to drink.
”Um, Ax?”, [Marco] I said. “ You have to drink where the little hole is in the lid.”
”A hole! In the lid! No spills!!! Lllls!!”
This was the coolest thing Ax had ever seen. I guess coffee cup technology hasn’t advanced very far on the Andalite home world.
~#5, The Predator
Rachel: "...We have a mission here. So lets go and get it over with."
Jake: "Rachel's right, we can debate animal testing some other day," Prince Jake said. "Let's just do this. In, Out and Right back."
Ax: <After These Messages.>
~#28, The Experiment
And perhaps the deepest thought to ever come from a tree:
Ellimist: Then why have another child? If not the disease, then the monsters, or a famine. Why have another child?
Tree: Disease take one. Monster take one. Famine take one. More children, some live.
~Chronicles #4, The Ellimist Chronicles
One line that should have been in Animorphs: The way that Marco's pop culture references and humor worked, he definately should have thrown in a "It's Morphin' Time!" somewhere along the way.
