“He's the developer of this Metal Gear REX weapon, and I like Japanese animation so I wanted to include a character who goes to anime conventions like Otakon in America.

In 1998 Kojima said the Otacon character had a silly origin: he is the developer of the Metal Gear REX weapon, and because Kojima likes Japanese animation he wanted to include a character who goes to anime conventions like Otakon in America. The image in his head was of a heavier guy who is always eating a chocolate bar, but along the way the character became the one seen in the game.
“This Otacon character had silly beginnings too.”
