Top three bizarre final bosses in gaming

Spoilers ahead!  

Going over the quirks and mechanics of each boss, what makes them interesting and how to beat them.  

3. The Master (Fallout 1) 

The Fallout series is set in a fictional post-nuclear wasteland where most of humanity has wiped each other out, the player must undertake various choices and decisions in the games that have a wide impact on the world around you. 

Mutant abomination Dr. Richard ‘The Master’ Grey, concluded the next step in human evolution was to create a mutant army to forcefully evolve humanity, referring to this as ‘The Unity.’ His belief was to have humans who have not mutated due to radiation forcibly mutated, thus eliminating everyone's differences and reducing infighting. 

There are two ways to defeat him:  

Attacking him, blowing him to smithereens; or, showing him the Brotherhood’s autopsy report on the Super Mutants, revealing them to be completely infertile.  

This leads Grey into realizing his ideals to be madness, blowing himself up along with his base, the cathedral, ending the game.  

2. Michel Reynolds (Illbleed) 

The Dreamcast game revolves around a girl called Eriko, who grew up around horror and is impervious to being scared. She enters a deadly horror theme park to save her friends.  

Each stage is a slasher film where you must make it to the end of the attraction alive, spotting traps and ambushes using the ‘horror monitor.’  

The twist is Michael Reynolds, Eriko’s father, built the park just to scare her.  

To meet him one-on-one, you must follow one simple step to achieve the secret ending; let your friends die in all the levels.  

1. Majora’s Mask (Legend of Zelda) 

After beating each temple of Termina; in the mountains, swamp, ocean and canyon, all of which have been cursed, we come toe-to-toe with the mask inside the moon. 

There are three stages of the boss, each more bizarre than the last. The Mask has tentacles at first, sprouting more limbs and forms as you fight it.  

Performing the can-can and shrieking like a banshee each time it's hit. Being a truly creepy, odd boss.
