Example Input: Question: How long has Nakayama been president of Sega when he was looking for a flagship series to compete with Mario? Passage:In 1990, Sega president Hayao Nakayama sought a flagship series to compete with Nintendo's Mario franchise along with a character to serve as a company mascot. Several character designs were submitted as part of a contest. Among the designs was an egg-shaped man wearing pajamas who resembled Theodore Roosevelt, drawn by Naoto Ohshima. According to Ohshima, the resemblance to Roosevelt was unintentional, saying he was influenced by a variety of characters. Retrospective sources have indicated Ohshima based the character on Humpty Dumpty and Mario. The Roosevelt lookalike did not win the contest; rather, another Ohshima character, a hedgehog named Mr. Needlemouselater renamed Sonicprevailed. As development of the Sega Genesis game Sonic the Hedgehog progressed, however, programmer Yuji Naka and the rest of Sonic Team thought the rejected design was excellent and deserved inclusion in the game. Since the character could not be the protagonist, the team retooled him into the game's main antagonist.
