Born to
avenge, Piccolo has always been very "no nonsense".
Some would say he was avenging his father but that's not really accurate.
Namek's are more or less asexual in nature. To "procreate"
they simply spit up an egg. SO technically it wasn't his fathers
death, but for all intents and purposes the theory holds.
He had an
objective of going after Goku. Piccolo entered the scene using
"Ma Junior" as his name in the tournament. Goku wouldn't
be defeated.
When
Raditz arrived Piccolo was excited to be the one to deliver the blow that
would kill Goku thru the process of killing Raditz. He did however
hear Raditz mention that two other Saiyans (Vegeta and Napa) were coming
to Earth. Piccolo saw the potential in little Gohan and decided to
train him. Of course, the way Piccolo trained him was a little
un-orthodox. He literally dropped Gohan in the desert and told him
to survive. After many months of this survival training Piccolo had
actually almost begun to like the boy. See, Piccolo never had any
nice thoughts or feelings but Gohan was slowly getting to him. He
would occasionally bring him food and drop it down if Gohan were hungry.
After they began to do the actual training Piccolo grew even more fond of
the boy. Gohan always calls him "Mr. Piccolo" (until he is
much older). The green guy had no idea he was setting himself up to
be Gohan's mentor (Gohan would dress like Piccolo for a very long time).
Piccolo is
a very strong and brave fighter! He has some really neat qualities
because he is from Namek. If Piccolo loses an arm - it grows back..
he also has very sensitive ears (in one of the movies he actually ripped
his ears off due to noise issues.)
Piccolo
wasn't very much fun on King Kais planet - he was actually a down right
party pooper. He trained alone and wouldn't indulge in any of the
humor available from King Kai. Also, Piccolo didn't eat. See,
Namek's don't need to. They survive on water alone.
On the
planet Namek Piccolo comes across a dying Namekian. Piccolo and Nail
decide to fuse. Piccolo was his funniest when this happened.
He started jumping around yelling about how great he felt. It was
truly out of character and refreshing.
Basically
Piccolo is a straight shooter who always is ready for the challenge.
He was able to overcome his hatred for Goku and I believe a part of that
was due to his caring for Gohan. As much as it annoyed him to be
attached to the kid, he was hooked for life.
Piccolo is
a crucial player thru much of DBZ. Once Buu is on the scene we see
him become the trainer again. He must teach Trunks and Goten how to
do the fusion dance - something he saw Kakarott do once and then later did
with Kakarott as an example.
Its
important to note that Piccolo and Kami are connected - in a way, they are
one. If one should die, then so does the other. This creates
major issues! At one point Piccolo has grown to love Gohan so much
that he literally gives his life for him.
Even
though the Saiyans begun to achieve Super Saiyan status, Piccolo remained
one of the strongest Z fighters.... he couldn't quite keep up, but
he was probably the strongest being after the Saiyans. Piccolo is
one awesome dude.
