This
episode begins with Krillan telling 18 to get out of the
area before Cell spots them. Cell already knew of their
presence and when Trunks told Krillan that he got very
scared. Now Cell was flying to stop Cell and he did
a pretty good job of fighting him and keeping him
away....that is until Vegeta shot Trunks out of the sky.
Piccolo who is back on Kami's lookout realizes the only
hope for Earth is Goku and Gohan because of Vegeta's erge
for a challenge. Now Cell was making his way towards
18. Krillan and 16 both tried to stop him but they
didn't stand a chance. This is where Trunks comes
out (it seems that he is USSJ or Ascened Saiyan as they
call him in English but that is not explained) and says he
will do whatever it takes to stop Cell and he blasts
Vegeta out of the sky. He now fights Cell some more
that is until Cell does solar flare and everyone's eyes
fail including Vegeta who just came into the scene.
Now Cell had nothing that could stop him and he absorbed
android 18 who couldn't see anything. Now Cell
starts to transform. Back on the planet where the
Namek's are staying Dende senses the power of Cell and so
do all the other Nameks.
