Cell Saga
A day before Dr. Gero appeared with 19, in the East Forest, a green insectlike creature came out of a small shell. This creature was imperfect Cell, who proceeded to Dr. Gero's 2nd lab. "Hello Dr., I am Cell, your creation from the future. I'm sorry, but I need more power before absorbing the androids." "What do you mean?!" said Gero, right before the funnel of Cell's tail was brought down on him, absorbing Dr. Gero whole. Cell smacked his lips,stating "I must let the backup 20 proceed, making everything go as I want it to be. I will then swallow up the 2 androids, and surpass the blueprints." as his wings grew shorter and his body grew bigger. For the next 3 days he absorbed everyone in the nearby towns, running into the Z-Fighters, who had recently fought 17 and 18, and explained his origin before retreating. Vegeta, angry at this development, shouted "I WILL SURPASS THE SUPER SAIYAN FORM, AND PROVE THAT I, VEGETA, AM STRONGER THAN AN INSECT!" Picollo went to see if Goku was awake, Krillin and Trunks destroyed Gero's secret bunker, and Tien went to train in the desert. Goku, who Picollo found awake, brought Gohan, Trunks and Vegeta to the Hyperbolic Time Chamber saying "We need to become strong enough to defeat Cell. He is out there, killing innocents, and it will not continue!" Vegeta and Trunks entered the chamber, beginning fierce training.Picollo encountered the androids on an island while training, and he took on 17, doing well, until suddenly, a yellow bolt of energy shot through his back, leaving him near death. Cell had arrived, and was startled to see 17 and 18 had awoken a model 16. He wasted no time defeating 16, who was no match for him due to absorbing Gero and the humans. He knocked away Android 18, and in no time at all had 17 by the neck. "You should've stayed locked up!" as the funnel of Cell's tail was brought down on 17, slowly pulling him through his tail, and Cell transformed into his 2nd form. "Dammit... Dammit, WHAT DID YOU DO TO MY BROTHER?!" screamed an enraged Android 18. Krillin arrived, sensing Cell's power increase, and fired a destructo disc. While Cell was distracted, he said" 18, close your eyes." unfinished
