Perfect cell

Cell (セル Seru) is the ultimate creation of Dr. Gero, designed via cell recombination using the genetics of the greatest fighters that the remote tracking device could find on Earth. The result was a "perfect warrior", possessing numerous favorable genetic traits and special abilities from Goku, Vegeta, Piccolo, Frieza and King Cold. He was one of the few Red Ribbon Androids not directly completed by Dr. Gero, instead being completed by Dr. Gero's Supercomputer in an alternate timeline. After achieving perfection, he sought to dominate the world through fear of his incredible power. He is the main antagonist of the overarching Cell Saga. Cell becomes fully humanoid in his Perfect form gained from absorbing Android 18, complete with a normal nose and mouth. His irises become pink (they stay red in the manga). His tail has been completely retracted, only the stinger remaining. This form is somewhat shorter and lighter than the previous one, being 7 feet in height. His wings have grown back, but he retains the shoe-like feet and upward-pointing horns from Semi-Perfect form. Purple stripes now run down each side of his face, similar to those of Frieza in his first three forms. Cell has an original personality engineered by Gero's computer to combine the character traits of his genetic constituents which would be most useful for a perfect weapon. Because his genetic composition includes DNA from Goku, Vegeta, and Piccolo, he is aware of their weaknesses and is therefore able to exploit them in battle. However, Cell's overall personality changes drastically with each transformation. After absorbing No. 18 and becoming perfect, Cell becomes significantly more arrogant and narcissistic in this form, due to the massive increase in power. After attaining the perfect form he had long desired, Cell admitted to Trunks that he had found himself with no other purpose, even killing Goku, which was Dr. Gero's intended purpose for Cell, did not seem to satisfy him. Like Goku, he just wanted to fight to enjoy it. Thus, he saw his Cell Games as the opportunity to discover a new purpose; to test his new-found power. This could also be attributed by his own vanity. In this form, Cell gains Frieza's polite mannerisms (though without the snide sarcasm) and ruthlessly sadistic personality, relishing in seeing people terrified, as he admitted to Future Trunks when he revealed his intention for the Cell Games. This was further shown in the anime, while waiting for the Cell Games, he chose to terrorize the people of Earth simply for his own amusement. Akira Toriyama himself surmised that the concept behind the Cell Games may have been influenced by King Piccolo's cells which makes sense as King Piccolo also enjoyed terrorizing the people of Earth in a similar manner and both broadcasted their evil intentions on television just to instill fear into Earth's population. Thus he possesses the villainous traits from King Piccolo, Vegeta, and Frieza. Much like Goku, Cell seems to take on a carefree and laid-back attitude, not losing any form of his composure until he was faced with the prospect of a being stronger than him. Cell has adopted Goku's, as well as Vegeta's, desire to battle strong opponents, which was another purpose of the Cell Games. The fact that prior to facing Super Saiyan 2 Gohan, Cell still chose to hold back his full power, Cell was willing to handicap himself in order to challenge his own limits. Despite this, however, if Cell finds that his opponents were not adequate challenges, he would not hesitate to finish the battle quickly or discontinue it, reflecting his arrogance.
