The Legend of Zelda: Link's Awakening
June 6, 1993
Dr. Wright from the SNES version of SimCity makes an appearance in the game. He's depicted as a lonely letter-writer that never gets any replies, as a pun on his name sounding like "write". His only active role in the game is being part of the Trading Sequence, since he would give Link the Cuccodex as a reward for giving him the Letter from Christine.
In the international versions of the game his name was transliterated as "Mr. Write", leading many gamers to believe him to only be a character based on Dr. Write, but since his original Japanese name is the same (Dr. Raito), that's actually him.
While Dr. Wright didn't make any other appearance in the Zelda series, a character reusing his sprites was featured in Oracle of Seasons, called Dr. Left, creating a pun on "Wright" (or "Write") sounding like "right". Dr. Left also returns in Minish Cap.
Being created specifically for the Super Nintendo version of SimCity, Dr. Wright is an original creation by Nintendo, so they could freely include him in their games.
