The pilot of the Wing Gundam, the
boy known as Heero is the most grim
and serious of the Gundam pilots. His
true name is unknown, but for this
mission of revenge he has been
code-named after the martyred leader
of the space colonies. Raised by the
scientist Doctor J, Heero has been
trained since childhood to be a ruthless
killing machine, equally proficient in
mobile suit piloting, personal combat,
demolitions, and computer hacking.
Though Heero's upbringing hasn't quite
managed to squeeze all the compassion
out of him, he is nonetheless callous
towards his allies, and cold-blooded
towards his enemies, and almost
suicidally careless of his own life. His
unexpected reluctance to kill Relena,
after she discovers his identity, is the
first step in Heero's gradual
reclamation of his own humanity.
Endless Waltz
The erstwhile human killing machine
has mellowed a tiny bit by the time
Endless Waltz begins. Still, he keeps a
close eye on current events, scanning
the computer nets for signs of trouble
and watching over his friend Relena
from afar. When Relena falls into the
hands of the Mariemaia Army, he
immediately rushes to her aid.
Secret History
Unlike some of his comrades, Heero
was intentionally selected and trained
for the role of a Gundam pilot. In an
Endless Waltz flashback, we get a
glimpse of how Heero was molded into
the ruthless killer we saw at the start
of the TV series. When a training
mission went awry and resulted in
innocent casualties, Heero's grief was
seen as a sign of weakness. Dekim
Barton, mastermind of Operation
Meteor, ordered Doctor J to re-train
the lad to eliminate these human
failings.
