The Beginning Of Cell

As you migth know,or if you have seen the Android Saga,you migth know then that Cell
is an Android.It's not like #16,#17,#18,#19 and #20 but it's more powerfull.
Even though the Androids do look like human,Cell does not.It more looks like a
monster.Even though Dr. Gero destroyed all the Androids up to 15,and the rest of 5
up to 20 still excist,Cell still lived.I know when Trunks said [that episode was 2
days ago],:If that Android is set free,it'll be the End of us All!!He shoots one of 
his biggest energy blast on The Androids,but the Androids are still intact.

Dr. Gero made Cell,but he didn't talked about him before his death.Even though it was 
better[i think] that he releases Cell instead of #17 and #18,he didn't let Cell go.
Cell was made in a room beneath all the Androids.The room was locked tidy,so that's
1 reason that Cell is not destroyd even though.After this,Cell came free and made 
the 'Arena' for the Cell Game....
