Cell Returns!

"I must give Dr. Gero credit for his brilliant design. My complete power had been restored even though I had lost Android 18. My cells had tasted the power and stored it away, reawakening it after the explosion while my new body grew."
— Cell

"You thought you'd never see me again, didn't you? Well, too bad, I'm alive! But I'm afraid I cannot say the same thing for Goku. Want to know how I survived the blast? Well, it's actually quite simple. It is all in here, it's part of my design. Every cell I have has a life of its own. I can't die, it's impossible. Even if I self-destruct, I will always come back."
— Cell

"Sorry, this is the only place I can bring him King Kai."
— Goku, during the previous episode's flashback

"I don't remember much after explosion, but somewhere amongst the planetary debris, the core of my being still existed. One living cell survived, and that is all I needed for my regeneration. Soon, that single living cell began to multiply into many. It wasn't long before I became conscious of my transformation. I could feel every part of my body growing. Crackling with new life and energy. My shapeless mass began to sprout new limbs. First my legs, then my arms... and in no time, my whole body was restored! At first, I could hardly believe that I had brought myself back from the brink of extinction. That is when I realized that each of my cells must hold memories of my former self, each one programmed to make me whole again! And, to my great delight,...I had returned with my complete power intact! Causing my own self-destruction was the best thing to happen to me! I was reborn! I must give Dr. Gero credit for his brilliant design. My complete power had been restored, even though I had lost Android 18.My cells had tasted the power and stored it away, reawakening it after the explosion while my new body grew."
— Cell, on his regeneration

"I also discovered that I had the ability to perform the Instant Transmission technique. Somehow during the blast, my cells had absorbed this knowledge from Goku. So, there you have it. You could say I am new and improved. Goku failed and so will all of you, but I am willing to give all another chance if you want."
— Cell explaining how he returned to Earth

"Trunks... my son... Kakarot, this is all your fault! How could I let this happen to my son?! He had sacrificed everything for me... but I did nothing but ignore him! No... I won't give up on him! There is still time to change things! Cell has crossed me for the last time! He had tricked me in battle, mocked my Saiyan ancestry, but this, this time he's gone too far! He will pay the ultimate price, for what he has done to my son!"
— Vegeta

"Gohan... this is it! It ends here! First I'll destroy you, then your friends and then this worthless planet! But before I do, I want you to remember something: I will live FOREVER!"
— Cell
