9 Secret Video Game Bosses You Need To Beat Before You Die

2. Sans - Undertale

For the most part, the majority of players won't ever have to think about fighting Sans, as it's only an option if you're specifically going for an all-killing "genocide run". For those that do though, they'll no doubt regret ever seeking him out.

The most interesting thing about this battle is that it isn't really a "battle" in the conventional sense. To get the upper hand on Sans you simply need to drag your cursor to a button, and he's dead in one hit. That said, the game makes it ridiculously tough to actually accomplish that seemingly simple feat.

Not only is it restricted so you move at a fraction of a pixel at a time, but all the while you need to avoid projectiles that take up the entirety of the screen. The torment just keeps coming in every conceivable shape and size, forcing you to memorise every section to a T as you're constantly sent back to the beginning over and over again.

In fact, it's sort of insulting that after all that he goes down with a single click of a button, an underwhelming end to a fight that most players won't even have to engage with.
