A Red vs. BlueFan Fic by multiple authors, collectively called the Freelancer Collaboration, found here at Fanfiction Dot Net. This collaboration charts the beginning of Project Freelancer from the points of view of the Director, Ace Pilot Four Seven Niner, Medic Killian Jay, and of course, the Freelancers themselves. The story rotates between narrators that include canon characters and Original Characters as the agents train and begin going on missions against the Insurrectionists and Covenant from the Halo canon as well as the simulation troopers. Alliances and rivalries build between the agents as they scramble for the top of the leader-board and attempt to chart the reason why they were here.
This work contains examples of:
The Ace - Carolina tends to stay at the top of the leader-board for a reason.
Ace Pilot - Four Seven Niner and her associate, Three Four Threer.
Action Girl - All the female Freelancers, as a matter of course. It comes with the job.
Big Brother Instinct - North is the poster boy for this trope, applying his protective tendencies not only towards his sister, but his whole team. Minnesota also becomes protective of Michigan when she's under stress, saying he grew up with a little sister. Virginia displays a big sister instinct towards Massa and West. Despite their status as only children, York and Carolina show something similar when the team's in trouble.
Big Brother Mentor - York is the most likely to take the gang out for drinks and encourage them to party, but he's that very rare nice, sane guy who will listen to the others' problems and try to help them from the first batch of Freelancers.
Big Eater - Virginia knows that regular meals aren't guaranteed in her line of work, so when she gets one, she makes it a good one.
The Big Guy - Penn, Maine, and Alaska play this up in nearly every sense.
Gentle Giant - Utah isn't the mostgraceful, but is kind towards his fellow agents. Surprisingly, Maine can come off as a gruff version of this as well, to those on his good side.
Black and Gray Morality - There are good people on both sides of the Insurrection vs. UNSC war, if both have members who are willing to take their good intentions to awful extremes or didn't have that great a set of moral codes to begin with... and then there are the Scary Dogmatic Aliens of the Covenant.
Black and Nerdy - Seems to be a running theme between the Counselor, Ark, Georgia, and Nevada. Chances are that if a Freelancer's melanin count is higher than average, they can mess up your day with nothing but a datapad and wifi access.
Can't Catch Up - How Virginia and Penn often feel in regards to Carolina.
Code Name - All the Freelancers and pilots have them, and the only real names revealed so far in-story have been Butch Flowers, Leonard Church, and Reginald. Later chapters reveal Darren, Jason Shaw, Hannah Steele, and Kimberly Britton, the lattermost last name added in the sequel. Phase Two also adds R. Cass, Jennie Rogers, Ramona Cassidy and Curt Bonomo to the list.
Cold Sniper - Wyoming and Virginia can both come off this way. Sota acts as this rather literally.
Disability Superpower - New Jersey lost an arm in battle before joining the project. She now has a full-on battle-arm that can punch dents in armor, crush sidearms in its grasp, and even power her Armor Ability.
Dr. Jerk - Killian can come across as this, but generally has his reasons, if you look at the patients...
To Absent Friends - when they at last straighten up enough to meet at a bar and discuss Michigan's memory.
Dying as Yourself - Massa and Mich's real names are revealed during their death scenes.
Dysfunction Junction: In the words of the Counselor: "Amongst the symptoms observed, I detected characteristics of post-traumatic stress, extreme narcissism, obsession and possible bipolarism. That was just Agent California, and he is one of the least worrying of the group."
Non P.O.V. Protagonist - Except the Counselor, and Four Seven Niner has only had one, so far. The only other Mauve Shirt to not really get his own chapters but keep showing up has been Three Four Threer.
Epic Battle Boredom - When South and Virginia are presented with more mooks than they can easily clear to get to Harper, they tend to consider it more a chore than a serious problem.
Fallen Princess - Hints about their past suggest that the Dakota twins grew up in an affluent family, but South rebelled and joined the military when it became clear that she was The Unfavorite. Her brother, of course, followed in her wake.
Loads and Loads of Characters - There are around fifty Freelancers (not all of which have been introduced), plus the Director, Counsellor and other personnel.
Loophole Abuse - The Freelancers' weapons are equipped with non-lethal lockdown ammo for most of their training sessions. This hasn't stopped Penn and Sota from finding some potentially (or actually) deadly workarounds.
New Meat - While many of the Freelancers come from military backgrounds, the high stakes and lack of history means that they all go through this stage, especially the second batch of agents to join the team.
The Only One Allowed to Defeat You - Harper and Cal definitely give off this vibe. While there are several competing for the honor of breaking Penn, he has claimed dibs on taking down or killing Carolina, Maine, and Alaska.
The Other Darrin - Certain characters have had a second writer do a chapter from their particular POV, due to time constraints.
Pity the Kidnapper - Wyoming is "held captive" by the Red Team during a simulation mission. They probably go through less stress after the other Freelancers arrive to "knock-knock" them out.
Poisonous Friend - Played with: South is definitely willing to do what she can to protect her brother's idealism, but Georgia thinks he's protecting Ark's ethics, when it's really Arkansas's stronger sense of right and wrong that drives him to becoming a Knight Templar, in part to protect Georgia's boundless optimism.
The Pollyanna - Florida maintains a front of cheery kindness, but has simply pushed the loss of his family to the back of his psyche.
Pungeon Master - It's not so much that Cal and Wyoming have horrible senses of humor as that the Hurricane of Puns and knock-knock jokes just keeps spinning between them.
Precision F-Strike - While many of the Freelancers swear as a matter of course, when ButchFlowers curses out loud, the rest of the agents take notice.
Vitriolic Best Buds / Friendly Enemy - Al and Penn tend towards this with anyone they even remotely consider a friend, especially each other. As Penn once put it: "It's weird. I hated this guy… I mean really hated this guy. But he always seemed to understand me… and vice versa. Anyone walking in would've seen me and Alaska, holding beers, conversing with each other… like we were best friends."
Warrior Therapist - Florida can happily dispense life wisdom or asskickings. Sometimes he gives out both. Carolina and Alaska can also figure out a good deal about their opponents by watching them fight, but tend to use it more to break brains as well as heads.
Weapon of Choice - While most of the Freelancers are trained in various weapons, many of the agents stray towards specific loadouts.
Wyoming favors a sniper rifle so heavily that when forced to wield an SMG, he actually dreads the prospect of firing it.
In one Scene, we see Virginia expertly shooting clays in the training room with a recurve bow. Sadly, we have yet to see this talent used in battle.
While Pennsylvania carries plentiful high-grade weaponry, by far his greatest weapons are his own two hands, Which are only rivaled in effectiveness by his unforgiving rage.
We Used to Be Friends - Cal and Harper, long before Cal joined up, were even more. When Arkansas and Penn leave the project, Georgia is devastated as much by the fact that Ark would do something like that as by Michigan's murder itself.
The Woman Wearing the Queenly Mask - Carolina has had to be the best and toughest for most of her life. She's not good at showing anything but her Iron Lady shell, even when she's nervous and with people who would bond with her.
