The one last level or mission just before the triumph or the much anticipated ‘end card’, is to defeat the boss. Boss fights usually test our patient, but the old bosses did much more. Play retro games to fathom the insanity of these bosses; defeating them would give a sense of achieving something incredible.

C’Thun – World Of Warcraft

Introduced with a patch 1.9 in 2006, C’thun was tough. It would swallow the players randomly and digest them slowly. Further, it had powers that could kill instantly kill anyone with a single ray of beam. Weakening him for short periods did little to affect his overall health. C’thun was a real pain for the gamers.

Yellow Devil – Mega Man

Mike Tyson – Punch Out

Bison – Street Fighter 2

It was necessary for the players to master various techniques, learning his moves and openings, thus becoming a better player to defeat him. Bison might have been tough, but he was not unbeatable.

Emerald Weapon – Final Fantasy 7
