In Metal Gear Solid 2, Otacon and Solid Snake form Philanthropy, an anti-proliferation organization. During the Tanker chapter, Otacon once again supports Snake via the codec and is in charge of saving the player's progress. He later appears in the Plant chapter, having infiltrated the Big Shell facility with Snake to save his stepsister Emma, who is among the hostages. Tragically, Emma is grievously wounded by Vamp and later dies in Otacon's arms. He later transports the surviving hostages to safety and then provides support to Raiden via codec for the remainder of the game. Lead character designer Yoji Shinkawa stated in an interview that Otacon was designed to look somewhat "tougher" than he did in Metal Gear Solid
