Biography
The Cell Jrs were created by Cell as a distraction method to occupy the Z-Fighter as he deemed them not worthy of being destroyed by him. Cell spat out eggs which sprouted into the Cell Jrs. The Cell Jrs are all telepathically linked and controlled by Cell. They are no where near the power of Cell but are slightly higher in power level than and Ultra Super Saiyan but no where near the power level of a Super Saiyan Level 2.
The Alternative Theory
Not much to say really. Cell when he gets lazy and is sexually frustrated releases these Cell Jrs who pleasure him sexually by giving him oil rub downs and bow jobs as well as other sexual favours. The question is, does this count as sexual intercourse? or masturbation as he is sorta playing with himself. Either way, when he refers to his "little cell" having LOADS of power, he doesnt just mean his dick and its no idle boast either!!
