With his never say die attitude, Bowser is certainly one of the greatest final bosses of all time. He keeps coming back in almost every installment of the Mario Brothers series with the same resentment for the protagonist as the game before. It was certainly an ironic moment for the Mario series when Bowser joined Mario in their fight against Smithy. Beyond this oddity though, Bowser is Mario’s arch nemesis. He’s a dinosaur with an infinite amount of hammers, and fireballs to spew at Mario and his friends. He takes on some interesting forms in Super Mario World and Mario 64 where he is larger than life and riding on clown copters. This list couldn’t be made without Bowser. He is the most noticeable final boss in video history.
