History Characters / HaloUNSCMarinesAndODST

* {{Nephewism}}: Was raised by his aunt. He loved her like the mother he never had, and him learning about her death when he comes home for leave after a disastrous HostageSituation sends him into a HeroicBSOD that he struggles to crawl out of for most of ''Contact Harvest''.

--> '''Marine''': (''After Chief destroys a'' ''[[HoverBike Ghost]]'' ''with a Scorpion'') Tank beats Ghost...\\
'''Marine''': (''Chief does the same to a'' ''[[TheJuggernaut Hunter]]'') Tank beats Hunter...\\
'''Marine''': {''Chief finishes up by taking down a'' ''[[DropShip Phantom]]'' ''and its compliment'') Tank beats '''''everything!''''' Oh man, I could do this all day!

* BadassArmy: On the ground, they're more than capable of holding their own against the superior numbers and technology of the Covenant. Though this is [[GameplayAndStorySegregation less apparent in the actual FPS games]], even there they can sometimes take down the Covenant's finest by themselves, especially starting with ''Halo 2''; you can take it even further if you switch out their starting weapons for something more powerful.

->'''Voiced by: Creator/AdamBaldwin (''VideoGame/{{Halo 3 ODST}}''), Rob Mungle (''[[Anime/HaloLegends The Babysitter]]'')'''

* InMemoriam: The UNSC military academy has been named the Avery J. Johnson Academy of Military Science.

* CrazyIsCool: In-universe they are all considered to be this (in large part because every ODST is someone who ''willingly volunteered'' to be dropped from orbit on a regular basis), but the 105th once again takes the cake, as "It takes a special kind of crazy to be a Helljumper."

* ElitesAreMoreGlamorous: To the point of being the only non-Spartans we ever get to play as.
** Additionally, most of the major ODST characters seen so far, including the cast of ''VideoGame/Halo3ODST'', are specifically Helljumpers from the 105th, making them badass even by ODST standards.
* InSeriesNickname: As noted above, the [=ODSTs=] of the 105th are known as "Helljumpers".

* CharacterDevelopment: Starts out a typical ODST with contempt for Spartans, but after Cal sacrifices herself to save his life, and he sees her humanity under the helmet, he changes his ways in the end, even throwing an apple at the head of a loud mouthed fellow ODST [[NeverSpeakIllOfTheDead who mocks Cal]] after the mission.

* JerkassRealization: [[spoiler:After Cal takes a fatal blow for him, O'Brien realizes what a total ass he's been to her. After the mission, his cocky demeanor is all but gone.]]

* OOCIsSeriousBusiness: In ''Halo 2'', Johnson is just as boisterous and comically hammy as he was in ''Combat Evolved'', and maintains this attitude through most of the game. Come ''Halo 3'', and he's noticeably more subdued and no-nonsense after the games introduction. The fact that Earth has been [[AlienInvasion completely overwhelmed and is vurrently being ravaged by the Covenant]], the Halo array is [[TheEndOfTheWorldAsWeKnowIt closer than ever to being activated on the Ark]], and the [[ZombieApocalypse Flood are on their way to finish everyone off]] probably has something to do with his lack of humor over the situation.

An all-volunteer special operations capable unit of the UNSC Marine Corps, the Orbital Drop Shock Troopers were the former candidates for the most badass CrazyAwesome humans to ever live. More commonly referred to as "[=ODSTs=]", they often deploy to the battlefield via drop-pod. From orbit. In order to become an [=ODST=], a soldier must first prove themself in another special operations unit before being transferred over and stripped of rank, going through an intense training regimen.

* CrazyAwesome: In-universe they are all considered to be this (in large part because every ODST is someone who ''willingly volunteered'' to be dropped from orbit on a regular basis), but the 105th once again takes the cake, as "It takes a special kind of crazy to be a Helljumper."

* FamousLastWords: [[spoiler:"Send me out... with a bang..."]]

* FamousLastWords: "Be...Human..."
** "And for one last instance...I'm human again".

* ImpaledWithExtremePrejudice: [[spoiler:A Brute Chieftain stabs him with the blade on his gravity hammer during the events of ''VideoGame/Halo3ODST''. Luckily, Romeo survives, though he can't fight for the rest of the game due to a pierced lung.]]

* UngratefulBastard: Only gets more angry at Cal every time the Spartan saves his life, to the point where Dutch even tells him (after the second save) that he really should be thanking the Spartan.

* WeWillWearArmourInTheFuture: It's noted to be fairly resistant to ballistic weaponry, though less so against Covenant directed-energy weapons. Its good enough to be comparable (and even compatible) with Spartan MJOLNIR armor.

* WeWillWearArmorInTheFuture: Far superior to those worn by Marine regulars, ODST armor is generally depicted to cover much more of the body than the standard kit (''Halo 2'' aside).

* WeWillWearArmourInTheFuture: It's noted to be fairly resistant to ballistic weaponry, though less so against Covenant directed-energy weapons.

** During the Halo Reach mission "New Alexandria", its possible for the player to hear a request for assistance from Buck. If the mission is to rescue his team from a Covenant Phantom, then he will be piloting a Flacon himself.

* FriendlySniper: A grimly cheerful guy who favors precision weaponry; even his heavy weapon of choice is a Spartan Laser.

* OOCIsSeriousBusiness: In ''Halo 2'', Johnson is just as boisterous and comically hammy as he was in ''Combat Evolved'', and maintains this attitude through most of the game. Come ''Halo 3'', and he's noticeably more subdued and no-nonsense after the games introduction. The fact that Earth has been [[AlienInvasion completely overwhelmed and occupied by the Covenant]], the Halo arrays are [[TheEndOfTheWorldAsWeKnowIt closer than ever to being activated on the Ark]], and the [[ZombieApocalypse Flood are on their way to finish both factions off]] probably has something to do with his lack of humor over the situation.

* GoOutWithASmile: [[spoiler:Seconds before his death, Ghost flashes a satisfied grin as he gives the command to self-destruct the prototype suit he's piloting, knowing his men have safely made it off-planet, and that he's recovered some remnants of his humanity.]]

* {{Adorkable}}: Comes with being the youngest and most naive member of the squad.

** "And for one last instance...I'm human again"
