10 Video Game Bosses You Can Trick Into Killing Themselves

4. GLaDOS (Portal)

Mastering the portal device in the Portal series is one of the most satisfying things you can do in life, allowing you to solve even the most confounding of puzzles by teleporting about the place and using the environment to your advantage.

These portals don't just come in handy during regular gameplay, either: they're key in helping you to defeat the first game's final boss, the cold, calculated, and menacing computer system known as GLaDOS.

When the battle starts, you'll have to grab the purple core that GLaDOS drops, and pop it into the nearby incinerator. This will annoy the already quite angry robot even further, causing her to start flooding the chamber with a deadly neurotoxin. On top of that, she'll start firing missiles at you, which will obviously hurt if you take a hit. But by using your portals, not only can you avoid this damage altogether, you can actually send the projectiles directly back to their source, tricking GLaDOS into damaging herself.

Line up your first portal so the missile goes into it, then line up your second portal so it's aimed at GLaDOS, and the explosive will rocket straight into her annoying metal frame. Do this enough times and you'll beat her, without ever firing a shot yourself.

Danny has been with WhatCulture for over ten years, and is currently Doctor Who Editor and WhoCulture Channel Manager, overseeing all of WhatCulture's Whoniverse coverage. In 2022, he took charge of WhoCulture and has grown it into the biggest Doctor Who channel on YouTube, and one of the biggest Doctor Who communities on the web full-stop. He has been writing and video editing since his early teens, and first got a taste for content creation after making his own Doctor Who trailers, off the back of a burning obsession with the Matt Smith era of the show. Like many his age, he first got into Doctor Who with the 2005 revival, but has since gone back and fallen in love with the classic years too. If you need someone to recite every Doctor Who episode in order, or to give you a random factoid about the making of Gridlock, Danny is the person to ask!
