Johnny "Akiba" Sasaki is a recurring joke character, cameoing in Metal Gear Solid, Sons Of Liberty and appearing more prominently in Guns Of The Patriots. Johnny's grandfather has a brief appearance in Snake Eater.
Eventually, in 2014, Johnny joined Meryl's Rat Patrol, with his teammates calling him by the nickname Akiba. He had a brief run-in with Old Snake, whom he didn't recognize.
While Snake and Meryl convene on their mission data, Johnny accidentally attracted a large battalion of FROGS by the gleam of his binoculars. The Rat Patrol and Snake did battle with the FROGS, and Johnny, in typical Sasaki fashion, lost control of his bowels during the battle and ended up defecating in his pants. He was then knocked unconscious by a stun grenade thrown by one of the FROGS, leaving him with his less-than-pleasant smelling behind in the air, much to the chagrin of his teammates. Snake patted him to wake him up, and they eventually defeated the FROGS. After Liquid Ocelot shuts off the SOP system present in all active soldiers (PMCs and Rat Patrol alike), Johnny is the only soldier on the battlefield not affected. After Snake collapsed in the middle of the warzone, Johnny was able to locate him and drag him to safety.
During their massive fire fight with the FROGS, Johnny reveals to Meryl that he joined the unit to get close to her, because he had been in love with her since the day that he laid eyes on her on Shadow Moses. Eventually he proposes to Meryl, however she declines and then in turn proposes to him, which he gladly accepts. After the mission has succeeded, Johnny and Meryl get married with fellow Rat Patrol members Ed and Jonathan serving as the priest and best man, respectively.
