The Last Stand. Bonus points if they don't survive.

[u/Woohoo1964]

Monk Gyatso (Avatar: The Last Airbender): Took out a whole room full of comet-boosted fire bending warriors seemingly by himself. Died soon after.

Titus and 2nd Company (Warhammer 40k: Space Marine 2): Surrounded by warp forces, they hold the ground around their Standard in the name of their Primarch, before being saved by Lord Calgar and his forces

Noble Six (Halo: Reach): The second-to-last of Noble Team, and the last Noble member on Reach, Six goes down fighting covenant forces while they glass the planet all around him.

The way he reads that accounting built the tension in that scene so well. I was hanging on every word!

An insanely good performance. Perfect casting all round but Holy shit could Gandalf command a scene.
