Let’s take a look at some final bosses who don’t die but not because of their immortality – it’s more due to the player who doesn’t outright murder them.
Liquid Ocelot – Metal Gear Solid 4
Liquid Ocelot is one of the strangest and yet most iconic villains in the entire franchise, especially given the character arc of Ocelot (and the supposed control that an attached limb of Liquid Snake held on him). From opposing Big Boss to becoming his comrade and then seeking to destroy the Patriots, Liquid Ocelot would face Solid Snake at the end of Metal Gear Solid 4 in hand to hand combat. Despite a rough battle, Ocelot didn’t die by Snake’s hands – instead, it was due to a new version of FOXDIE, which calls back to Liquid Snake’s death in Metal Gear Solid 1.
