He is perhaps one of Son Goku's longest and best friends in the entire series. They have been through the thick and thin from Kamesennin's rigorous training to the Budokai. His significance has also faded as the story moved deeper into the Z series in a Super Saiyan dominated world.
Krillin has been Goku's best friend since
they studied martial arts together under
Master Roshi as kids. Krillin provides comic
relief in tense situations as he tries to keep
up with Goku and some of the other more
powerful warriors. But don't get the idea
that he's a helpless buffoon. A good fighter
on his own accord, he's always there to help
Goku. He can and has saved his friend's life
more than once. In fact, Krillin unleashes an
incredibly powerful energy blast shaped like
a flying disc that literally slices through
mountaintops.
Krillin is incredibly dedicated to his friends,
especially Goku, and holds friendship in high
value. He is willing to fight against the
Saibamen and Saiyans even though he
doesn't want to die. Goku encourages Krillin
to have confidence in his own abilities as
Krillin learns to be a remarkable fighter ,that is, for an Earthling.
Krillin volunteers to be one of the crew going
to Namek to gather the Namekian Dragon
Balls. On this journey he once again gets to
prove his loyalty, courage, and fighting skills.
His power is enhanced even further by the
eldest Namekian, Guru, when he awakens
the sleeping power within Krillin. He will need
every ounce of this power he has to fight
against the evil forces assembled on Namek.
