What is a fateful encounter in Pokemon SoulSilver?

In Pokemon SoulSilver, a fateful encounter refers to the event where the player character encounters and has the opportunity to catch the legendary Pokemon Ho-Oh (if playing the Silver version) or Lugia (if playing the Gold version) near the end of the game. These legendary Pokemon are the signature legendaries of the Johto region and hold significant importance within the game. Fateful encounters with Ho-Oh or Lugia provide trainers with a chance to capture and add these powerful Pokemon to their teams.
