Why is he so perfect?
>The spots on his head are asymmetrical
He was born that way
Because Cell consumed 17 & 18, the summation of which is 35, which on the periodic table is Bromine, an element with flame retardant potential. Since Kamehaha waves & ki blasts have high temperatures, the flame retardant produces hydrobromic acid which interferes in the radical chain reaction of the oxidation reaction of the fire making Cell highly resistant to Saiyan attacks.
