9 Scrapped Bosses Used In Other Video Games
8. Metal Gear Solid 2's Old Boy - Metal Gear Solid 3: Snake Eater
Hideo Kojima is one of those peerlessly productive creatives who comes up with far more ideas than he's ever capable of implementing, though one of his discarded bosses for Metal Gear Solid 2: Sons of Liberty actually ended up being re-used for the third game.
Metal Gear Solid 2 was originally set to feature a boss called Old Boy, a former mentor of Big Boss who was over 100 years old and rendered biologically immortal due to mutant enzymes in his body.
For reasons unknown Old Boy was scrapped, yet Kojima ended up recycling core tenets of the character for two of Metal Gear Solid 3: Snake Eater's most memorable bosses - The Boss and The End.
Old Boy's backstory as a mentor to Big Boss became a defining aspect of The Boss' character arc, while The End was also roughly 100 years old and a supremely skilled combatant not unlike Old Boy.
Considering that The Boss and The End are ultimately two of the most compelling boss characters in the history of the Metal Gear Solid franchise, it's fair to say that everything probably worked out for the best here.
