10 Biggest Boss Battles In Video Game History - Ranked By Size

As anyone that has ever read any H.P. Lovecraft will tell you, there exists within mankind a size to sanity ratio.

Facing off against MGS V's 15-metre tall, unpronounceable Metal Gear Sahelanthropus might test our robot-killing skills the maximum, but – save for the occasional rage quit – we can keep a cool head, persevere, and hope it's sophisticated AI has an off-moment.

Equally, Resistance 2's Leviathan might remind us of our favourite city-destroying mega-monsters, be it King King, the Cloverfield monster, or Ghostbuster's Stay Puft Marshmellow Man, but he's not enough to distract us from firing our rockets down it's throat when it roars in our faces.

However, there is a limit to what the human mind can take. Much like in the tales of the Necronomicon when any unfortunate character dares to glimpse the “Elder Things”, there is a point when something can be so big as to become difficult to comprehend.

Rather than protect us from such absurdities, video game developers are increasingly enjoying showing off their exploitation of ever-improving computer hardware by having our video game protagonists face increasingly humongous bosses. Not only are these bad guys often some of the strongest and toughest in a video game, but there mere presence is enough for our protagonist to wonder why they're even bothering trying to kill the damn thing. Here are the bosses so big that it's made us question our own insignificance.

Approximate Size: 160 metres

To say a human being, approximately 1.8m tall, is capable of taking down an alien species so big that we initially confused it with being a space craft, is perhaps overestimating our abilities.

And yet, Shepherd being the badass Spectre that he is (my Shepherd was male), he is able to do just that – albeit after possibly dying and reloading the previous save a few times, as all the best heroes do (just look at Tom Cruise in The Edge of Tomorrow).

After landing on Rannoch and attacking a Reaper base, Shepherd and his team attempt to take out the Reaper tech and so free the Geth of their control.

Unfortunately, while in the middle of this, an enormous Destroyer class Reaper crawls out of the ground and begins firing its huge lasers at you. While the larger Reapers stand at over 2km in length, Shepherd rarely battles them directly, allowing the Citadel fleet the opportunity to take down Sovereign, while the final battle against Harbinger is a more just a run, duck and hope event.

Fortunately, with his back against the wall, Shepherd proves in the battle of Rannoch that the bigger they are, the harder they fall.
