Captain Silver is a retired veteran of the United States military; he is always accompanied by a parrot named Flint (Polly in some English translations). Flint's original owner was Silver's war comrade and subordinate Randy, who was killed by Fata Morgana, apparently during the invasion depicted in Sonic Wings. Silver fights Fata Morgana to avenge Randy's death, just as he cares for Flint in Randy's memory. Character notes in Pseudo Sky Rascals reveal that Silver's title in Sonic Wings 2 was meant to be Colonel and not Captain; however, so many magazines got the title wrong, the designers changed the title to Captain for Sonic Wings Special.
