9. Waist-Up Bad Guys
Okay, admittedly, there aren't that many other ways which spring to mind to represent scale on screen, but showing bosses from the waist-up is undoubtedly a tiresome cliche, at this point.
Every gamer can no doubt pull from memory at least three or four examples of encountering a boss - usually on the roof of a tall building, let's be honest here - who is so huge that they can only be seen from the waist up.
The Galactus fight in the Lego Marvel Superheroes game is a great example of this (as well as a great many other) boss fight trope. Appearing from the waist up, the destroyer of worlds torments and assaults the Avengers and friends on a rooftop, with audible "Nom Nom Noms" as he fills his other-wordly stomach.
The Darksiders series also leans into waist-up baddies, as do so many other titles it would be impossible to list them all, but one thing we as gamers can say for certain is that we are tired of this cliched set piece, and hope that developers can find new and interesting ways to represent massive bosses going forward.
