Visser

I would spearhead the invasion of Earth.  I would take charge of our greatest conquest.  I would stand alone atop the Yeerk military hierarchy.
I was to become Visser One.

<Soon he'll kill you.  Soon evil will destroy evil.>
<The pain may well be yours as much as mine.>
<No, no it won't.  Because for you it will be defeat.  For me it
will be liberation.>
--Eva, Visser One

My name is Edriss-Five-Six-Two, of the Sulp Niar pool.

"There are memories of youth spent in a place known as Cow Town or Podunk or Arkansas, with the three terms roughly synonymous, and yet also referencing multiple fictional locations.  I sense a fundamental lack of organization here in this brain."
--Visser One

"My host...her mind, her senses, she....she..."
"She what, Visser One of the Yeerk Empire?  She
what?"
"She was
alive!  She was alive!  She was more alive than me.  More alive
than any of us."
"You had become Jenny Lines, Visser."
"What?"
"You were addicted, Visser One.  You became addicted to humans."
--Visser One, Garoff

"You know who this is."
"Yes."
"Your mother."
"No. 
Not my mother.  A Yeerk."
--Visser One, Marco

"Marco, your mother loves you."
"I know my mother loves me, Visser.  And let me make one thing clear:  There's no deal between us, you and me, Yeerk.  I'll kill you for what you've done to her and to my dad.  Count on that."
--Visser One, Marco

<He was in love with love.  He had gone over.  He had become human.>
<And he chose to die rather than surrender his humanity.  And still, you think you will conquer us?>
--Visser One, Eva

"What do we do, fearless leader?"
<It's your call, Marco.  Your mom, your call.>
By the Kandrona itself, the tiger was human, too!  Where they all human?
--Marco, Jake, Visser One

<At least now you'll die and I'll be free.>
<You'll die, too, human.  What freedom is there in death?>
<I'll be free of you.>
--Eva, Visser One

"Yes.  Well, about those Andalite bandits, since we're past all this unpleasantness between us, I guess I could tell you..."
<What could you tell me?>
"Oh, nothing.  Nothing at all, Visser.  Not a thing."
--Visser One, Visser Three
