Spearow

SPEAROW was a Spearow captured by Red very early in the Gen 1 playthrough. He was eventually traded away for Dux in Vermilion City.

History
SPEAROW was not utilized much after being captured. After obtaining the Helix Fossil, Red traded the Spearow away for a Farfetch'd named DUX, who became an integral character in part due to the game due to his learning the move Cut.

Personality (Lore)
Not much is known about SPEAROW's personality. Since SPEAROW was traded in order to obtain DUX, he played an important part in adding DUX to the main team before being a major fatality of Bloody Sunday.
