A planet where the Enterprise-D crew took shore leave in 2367 and where a prank between two brothers left young Willie Potts infected by a deadly parasite.
Ogus II is a planet visited by the USS Enterprise-D at the start of the Next Generation episode Brothers. The crew and their families are enjoying shore leave there when the story opens.
During a game, Jake Potts frightens his younger brother Willie, who runs off into the forest and eats the fruit of the cove palm. The fruit carries parasites that are lethal to humans, and Willie has to be sealed in a quarantine field in sickbay.
Because the infection cannot be cured aboard ship, the Enterprise leaves Ogus II for Starbase 416. The planet itself is not seen on screen; its role is to set up the medical emergency that makes Data's hijacking of the ship so dangerous.
