* From ''Origins: Part 1'', the Forerunners going to war.
* The battle in "The Duel". One Arbiter vs. Hundreds of Covenant, including a wraith and 3 supersized Hunters? CurbStompBattle on the troops, 3-0 against the Hunters, and I'm pretty sure he took out one by throwing the Wraith at it...
* ''Prototype''. A marine uses a prototype, upscaled Mjolnir suit with built in weapons, and uses the time left before it's self-destruct mechanism activates to allow his men to escape. The suit resembles a Gundam, in both appearance and the improbable amount of Covenent it takes out. Badass on so many levels.
** To be precise, it's actually based on one of the Marauder Suits from ''Literature/StarshipTroopers'', both in design and combat style.
** Does he even get points for that voice filter he uses when he casually pulls up alongside the lowly Marines?
* "Darkness born in eons past became a threat to all life once again. And humankind and the Covenant who had drowned for so long in each others blood, were united if only for the briefest moment against a terrible enemy they both shared. Righteous souls continued to fight, believing that they could defeat the darkness. And as they fought together, they stumbled together, into peace." All the while, we're shown scenes of the Covenant and the UNSC fighting alongside each other against the Flood, while Sacred Icon Suite 2 blares in the background. Badass.
* The sequence in Origins of the Covenant and Humans fighting against the Flood. '''''Epic'''''.
* Every single moment of "The Package." After numerous shorts with [[BittersweetEnding Bittersweet Endings]], a Spartan strike team led by ''Master Chief 117'' is shown launching an attack on a Covenant flagship to rescue [[spoiler: Dr. Hallsey, Cortana's template]]...and as they charge into battle, [[ThemeMusicPowerUp the sound of the franchise's main anthem swells up,]] letting us know that this time, things will end better.
