Lance Leader/Connor SinclairThe leader of Damocles Commando Team 1, who's served alongside Dominic "Gunner" Paine. Also the player character, who has to deal with it when the mission goes bad and rally what's left of the Damocles Commando to complete it and escape.
- Everyone Calls Him Lance Leader: Until Pirate's Moon when he was given a character and voice.
- The Faceless: None of the members of the Damocles Commando are ever shown, only heard.
- Featureless Protagonist: Up until the expansion Pirate's Moon.
- With This Herring: Justified considering that most of the Damocles Commando got shot down, but Lance Leader still starts with Bushwhacker and 3 MFBs to topple an entire planet of hostiles, and frequently has to step up an accomplish things that were intended to be done by whole lances or companies with only a couple of 'Mechs or a lance.
- During the game you will have to complete at least one operation that has wiped out another team; when you move into Operations Area 2 you are informed that Damocles Commando Team 2 managed to blow the dam that was their first objective, but were destroyed by responding Clan units. Now you and Dominic have to do the rest of their work, along with tracking down and destroying the factory that was the target of Operation 1 but moved before you got there.
Dominic "Gunner" PaineDamocles Commando 1-2, Sinclair's lancemate even from before the game, and met up with at the end of Operation 1. He starts with a Shadow Cat Prime there. He's the last lancemate you get in Pirate's Moon, having stolen a pirate Atlas.
- The Faceless: None of the members of the Damocles Commando are ever shown, only heard.
- Accidental Pun: "I bring the Paine."
- Accidental nothing. Dominic is repeatedly shown to have the greatest sense of humor on the lance, which he applies most often to annoying your other lancemates.
Epona RhiThe third lance mate who was once Damocles Commando 3-4 and met up with at the end of Operation 2, where she initially pilots a Bushwhacker just like you did. She's the first lancemate you meet in Pirate's Moon. Tends to be somewhat dour and usually the least-appreciative of Dominic's joking. During Pirate's Moon, she established a relationship with one of the locals before he was killed in action.
- Oh Crap!: A highly memorable one, give that the fight you're about to have going to her rescue can easily go catastrophically wrong at high difficulties.Blake's blood, I'm dancing with an Annihilator in here!
- The Faceless: None of the members of the Damocles Commando are ever shown, only heard.
- Hartman Hips: According to Alan in Pirate's Moon. She's furious at the suggestion.Love you too Epona, wide hips and all!
Alan MatillaThe last lancemate you get in MW3, he was the last man out of the DropShip Black Hammer before it crashed, and initially pilots a Sunder. He's the second lancemate you get in Pirate's Moon. Alan is more optimistic and personable than Epona, with a generally sunny disposition.
Mechwarrior 4: Vengeance
Omega Lance / The Resistance
- Lord Roland: "Then what do you want!?"Ian Dresari: "I want my family back."
- And the Adventure Continues: The good end, where Ian gives the throne to Joanna and departs; other planets need liberating too, in his opinion. Black Knight suggests this isn't canon, but then again Black Knight itself may not be...
- The Faceless: Makes no on-screen appearances in Black Knight outside his 'Mech, so we don't know what's changed in the time since Vengeance, where this was averted.
- The Hero: When you're playing as him.
- Royals Who Actually Do Something: He's the son of a duke of Kentares IV, and actually becomes duke in one end; in the other, it goes to his sister.
- Sudden Sequel Heel Syndrome: In Black Knight, becoming a Disc One Final Boss due to actions taken by the game's Big Bad. According to materials outside the game, he was smeared by Katherine Steiner's Loyalists and may not have actually done anything to piss off the Black Knight Legion, the latter of which are unknown to be canon in BattleTech at large.
- Peter Dresari: "Ian, your lancemate on this mission will be Casey Nolan. You'll learn to ignore him; the rest of us do."
- Let's Get Dangerous: Casey tends to be first in line when it comes to advocating immediate, violent action in response to whatever Steiner atrocity has just been threatened or carried out.
- Power Trio: In the early game. Casey tends to act as a voice for the collective desires of Omega Lance, advocating immediate strikes against Steiner to make them pay for their actions. He retains this trait long after the Power Trio portion of the game, but is generally more collected about it as his faith in Ian grows.
- "It's Gonzales, sir."
- Power Trio: Gonzales usually provides a more stable, long-term view of the situation than Casey, but is more determined to attack and destroy the enemy than Rathburn, functioning as a balance between the two in the early game.
- "I was beginning to think they'd just keep coming!"
- The Heart: Of Omega Lance. While the other lancemates are usually focused outward on the state of the rebellion or Steiner's actions, Jen is more concerned with things inside Omega; how her performance in combat is seen and how Ian is handling whatever crisis is currently being inflicted on him.
Terra RisnerA MechWarrior who was originally part of the Royal Guard when the planet fell to Steiner occupation, you rescued her among other PoWs on the way to be executed late in the desert sequence. Firey, and trained as an assault specialist, Terra prefers to go toe to toe. She speaks to you relatively little after she joins your lance compared to Casey or Jen, but is vocal enough on the comms.
- Insistent Terminology: She usually refers to Ian as "Commander" or "Sir", in contrast to Jen's "Lead" or "Ian".
Damon SquireA MechWarrior who was originally one of Joanna Dresari's bodyguards, he's fairly skilled but picked up late enough in the game it's likely your core pilots are more capable than he is. He wants to serve the Dresaris, and will abandon you to try to rescue Joanna if you don't attempt it yourself in the endgame. Conversely, if you try to rescue Joanna, he'll drop with you as a fifth member of your lance. In Black Knight, he's part of the anti-Ian resistance movement, likely in response to Ian abandoning his sister.
- "Omega Support, sweep the operational area. Window, two hours, twenty minutes."
- Mission Control: Of Vengeance. It is unknown if she is still working for Ian during Black Knight.
- Power Trio: Rathburn is more cautious in the early game, in contrast to Casey's desire to close with the enemy and destroy them and Gonzales' more measured aggression. Some of this is a function of her doubts about Ian; after she trusts his skills more Rathburn becomes notably more aggressive in her approach towards the missions and what jobs Omega takes on, culminating in the Capital sequence where the Resistance is sending her requests for Omega Lance to take on the missions that the Resistance itself can't do.
- "I kept your father's 'Mechs in shape for him. I'll do the same for you, young Dresari."
- Defector from Decadence: He ended up in a Dresari prison during the events of Black Knight.
- The Engineer: Gives you advice on what weapons and 'Mechs to deploy in the missions you go on throughout the Vengeance campaign and is stated to be the one working your MechLab there.
- Insistent Terminology: He refers to Ian as "young Dresari" through most of the campaign. During the Alpine sequence, he adds "young Duke" as well, and it also turns up for the rest of the campaign.
- Dare to Be Badass: In the opening scene of the campaign, he cautions Ian against revenge, but gives a speech about being the man Ian's father thought Ian was; this constrasts with the last message of the Duke, who encourages Ian not to confront Steiner.
- Mentor Occupational Hazard: After the Lunar missions he's still alive a little longer, but you don't see his 'Mech in person: he's ultimately killed leading Steiner forces away from you.
- "It's true. You came back. You came back."
- The Heart: Joanna feels the suffering of Kentares' people keenly and always pushes for what's best for them. Though Ian does most of the important fighting, Joanna is the one who handles the Resistance as a whole. In the ending she survives in, Ian recognizes this and has her crowned Duchess rather than becoming Duke himself.
Omega Forward/Foxtrot/Private Eye
- "Just follow the big skid marks in."
- A Father to His Men: Forward One loses a scout party in one mission and asks Ian to look for them during it. Unfortunately, you can't find them.
- Deadpan Snarker: The comment that's used for Forward's quote? It's about a crashed DropShip. Similarly, other elements of Forward make a few snarky comments about Steiner forces they're observing, including one where they outright complain about almost being stepped on and still not noticed by a pair of Steiner Vultures.
- The Faceless: The most that's ever seen of Forward are their scout cars in-mission, and often not even that. Forward are apparently very good at their jobs.
Lord RolandThe Steiner politician and noble who actually handles the day-to-day running of Kentares, he tends to the authoritarian and does not appear familiar with Kentares' history; if he was, he wouldn't order quite so many massacres as one of the planet's formative events was the Kentares Massacre when Kurita forces killed over 80% of the planet's population during the Second Succession War. Vanda Castro points out his tactics are exceptionally poor choices for this particular planet. He doesn't listen.
- Fat Bastard: Though never seen save in the small comm window, he appears to be carrying some weight.
Vanda CastroAn older woman and Steiner Major, she has formal authority over Steiner military operations on Kentares but in practice has relatively little actual power, as her nominal "subordinates" are both issued orders directly by Roland and share her rank despite her supposedly commanding them. She's a savvy commander who only a couple of hours after introduction is raining 'Mechs on your head, but her authority is frequently undermined by Lord Roland and the other two Steiner majors are semi-controlled mad dogs on their good days.
- Big Bad: Subverted. She's introduced as a dangerous and competent commander, and she counterstrikes against Omega Lance within hours of becoming aware of their activities...but ultimately doesn't play much of a role in the game.
- The Cassandra: In the collection of psychopaths and megalomaniacs running the Steiner war effort, she's the only one with sound tactical sense and repeatedly predicts the Resistance's moves. Nobody listens.
- It's so bad that towards the middle of the campaign Jen McQuarrie actually lampshades that no one listens to Castro and they Resistance is lucky they don't.
- The Unfought: Castro is only fought if you do the armory raid mission, which also condemns your sister to death. If you save your sister and do the palace attack, she doesn't appear, leading to...
- What Happened to the Mouse?: Presumably she was killed by Resistance forces somewhere if you don't make the armory raid, but this is never explained. As the only remaining Drop Ship in Steiner hands was at the palace, it's unlikely she escaped.
Duncan BurkeThe technical slayer of Peter Dresari, and the organizer of an attempted massacre that you must thwart along the coastal swamps before you proceed to the capital in the mid-late game. Burke brags about Peter's death and generally comes across as thoroughly unpleasant and possibly psychopathic. He's noted to have been responsible for several atrocities while fighting against the Clans; considering the nature of the Inner Sphere's wars against the Clans as defensive or reclaiming lost territory, this almost certainly means whatever he did was against his own side!
- Ace Custom: He pilots a custom Thor loaded with twin Clan PPCs backed by an LB-10X autocannon and a small SRM launcher.
- Better to Die Than Be Killed: After Ian wins their duel, Rathburn asks if Burke ejected; Ian says no, and speculates Burke was afraid to. Left unstated is that that Burke probably expected he'd be killed in his ejection pod if he punched out, just as he'd killed Peter.
- Suspiciously Similar Substitute: For James Kulin. They look very alike down to the moustache, are bloodthirsty to the point of psychosis, attempt to stage a massacre, pilot a custom Clan heavy built around a dual-ER-PPC armament, are killed by Ian, and are explicitly stated to have not ejected from their dying 'Mech. They have very different personalities, however.
James KulinA captain in the Steiner military, and one of the bosses Ian has to fight during the final mission of the desert campaign. Due to the resistance's growing success on the Hadra Peninsula, he tries to deny them resources: specifically, the planet's former defense forces who were taken prisoner. He does this by ordering mass executions at first, and later attempts to directly destroy a POW camp the Resistance and Ian are liberating. He pilots a Mad Cat, and commands a lance of three Vultures.
- Ace Custom: He pilots a custom Mad Cat, basically a downgraded Mad Cat D from the tabletop; twin Clan PPCs backed by a pair of Streak SRM-6s and two machinegun arrays.
- Insistent Terminology: Always refers to Ian as "Mister Dresari", explicitly denying any title of nobility to delegitimatize him.
- Pay Evil unto Evil: Kulin is killed in his cockpit, as he intended to kill the POWs you're liberating when you encounter him. If she's present, Terra Risner will be vocally pleased with his appearance in the mission area and his death; Jules Gonzales will opine that it's one less cockroach infesting the planet.
- Smug Snake: Kulin is full of barbed politeness and relatively softspoken, in comparison to Burke's brash psychopathy.
William DresariIan's cousin and titular Duke of Kentares under Steiner, youngish (probably about Ian's age), seen little and somewhat sinster of aspect. Ian refers to him as having been a bully all his life, and good at it. He defeats Peter Dresari in 'Mech combat, then lets Burke kill Peter after he ejects. He's faced in the last mission of the game, where he pilots a customized Daishi packing a huge number of Ultra AC-5s in the original. In the patched game after installing Black Knight or the compatible standalone patch, he's instead loaded out with a large number of pulse lasers and a single Clan PPC. The patch also changes it so his start position is more logical and you are not immediately under fire from him.
- Ace Custom: Attempting to recreate his original Daishi in the MechLab will reveal it's been significantly tinkered with in base stats, including engine, to mount the number of guns it does. It is by far the hardest single opponent to fight in the game, using what's easily the most broken weapon in stock Vengeance. The fit used by William in the patch is significantly easier to fight, but doesn't seem to overheat at all, though it quickly should.
- The Computer Is a Cheating Bastard: Unpatched MechWarrior 4 leaves him equipped with a plethora of the most broken weapon in the game, magically appearing in combat range at the end of a brief cutscene. The patched version of the game still gives William an edge, but it's nowhere near as insane.
- The player can defy the "magically appearing in combat range" part of William's edge over them if they're quick enough to crouch their 'Mech before the cutscene's autopilot starts; the game's autopilot AI won't take you anywhere, as it apparently doesn't know how to un-crouch.
- We Can Rule Together: As the Resistance closes in on the capital, William offers Ian a chance to leave Kentares in exchange for another world to rule, or to share power on Kentares. Ian of course refuses.
Mechwarrior 4: Black Knight
Black Knight Legion
- Canon Foreigner: These guys do not appear to officially exist outside the 4: Black Knight expansion, although 'Mechs bearing their insignias can be fought at points during 4: Mercenaries' campaign, most noticeably during a mission on Wernke, where Specter Lance (see the 4: Mercenaries folder) has to destroy a dropship guarded by such 'Mechs before having to fight Burr's Black Cobras.
- Private Military Contractors: They're all mercenaries.
- Roaring Rampage of Revenge: As a Vengeance expansion following up on the events of said game, this was probably going to be the motivation for these guys' actions at some point during the campaign; after an assault on one of their bases by combined Steiner and Dresari forces that cost them their leader, they seem to take some time off from mercenary work to get revenge on their aggressors.
Eric McClairPlayer Character of 4: Black Knight
- The Hero: Of Black Knight.
- Anti-Hero: He's a mercenary.
- The Leader: Essentially takes Col. Lawhorn's place after his death, even taking up the latter's callsign "Black Knight".
- Colonel Badass/The Leader: The leader of the Black Knight Legion and first to use the callsign "Black Knight" in the campaign's run. The 'Mech he uses in his very first appearance on the field happens to be the only one of its kind to appear in the campaign, the 75-ton Black Knight, which Eric eventually gets to use himself after his demise.
- Killed Off for Real: Pretty early on in the campaign. The events that led to his death are the motivation for the protagonists' actions throughout the rest of the campaign.
Mechwarrior 4: Mercenaries
SpecterAn opportunistic mercenary loyal only to whoever's footing his bill.
- The Ace: Specter graduated at the top of his class in the pilot program on Outreach for larger mercenary outfits to "sponsor" smaller ones.
- Player Character: The framing device is an aged Specter (post-Jihad) telling the tale of his exploits.
- Only in It for the Money: "We're here for the paycheck, not the politics."
Specter's Mercs (Various)There are many, many mercenaries Specter can recruit to his side.
- Blonde, Brunette, Redhead: The three female lancemates with lance commander credentials you can hire at the outset: Mustang, Goat, and Blaze, respectively.
- British Stuffiness: Beowulf.
- Brave Scot: Claymore, complete with imitation Sean Connery accent. Plunk him in a Highlander to complete the trope.
- Cowgirl: Mustang, the most expensive and highly skilled (at the outset) pilot you can hire, even has the cowgirl accent.
- Fiery Redhead: Blaze, a highly skilled potential secondary lance commander evokes it with her name, even.
- New Meat: Scooter's said to be "wet behind the ears".
- Street Smart: Rubius was "raised on the streets".
- Terse Talker: Spirit is rather quiet. Most evident during ready-op call. She just goes "Spirit. Ready-op."
CastleSpecter's mission control.
- Berserk Button: Towards the Clans. Read other tropes for her below for details.
- Conveniently an Orphan: Castle was orphaned by the Clan Invasion. The period the game takes place is about fifteen or so years after the Clan Invasion period, putting her in her thirties.
- Mission Control: The two constant voices in all (non-Solaris) missions are Specter and Castle.
- Norse by Norsewest: Castle hails from the Free Rasalhague Republic, which is basically Scandinavia IN SPACE, and it shows in her accent. Before the Clan Invasion, it was an entire former Draconis Combine march that eventually seceded with tacit approval from Luthien, but it was unfortunately right in the center of the Clan Invasion Corridor. The Clan Invasion reduced it to a scant handful of worlds, none of which are the original capital world of Rasalhague.
Aisa Thastus / FalconA fierce trueborn Jade Falcon Star Colonel whom Specter encounters on New Exford. Depending on how events play out, Specter can wind up taking her as a bondsman.
- Proud Warrior Race Guy: from possibly the most ardently Crusader-minded of the Clans.
- First Name Basis: In her pre-mission ready check, she doesn't use her callsign (Falcon), but her first name. No one else responds with anything but their callsign.
Duncan FisherSolaris announcer and commentator who loves almost everything about the games.
Colonel Burr and the Black CobrasA rival mercenary unit who often show up to get in Specter's way.
- Private Military Contractors: Just like Specter and his unit, they're mercenaries.
- The Rival: To Specter's unit. Depending on how events play, this can come to a head on Wernke, where Specter fights Burr himself, who brings a lot of Mechwarriors with him, outnumbering and potentially outgunning Specter's lances for that mission.
Peter Steiner-DavionYounger brother and ally to Victor Steiner-Davion, and eventually the Archon of the Lyran Commonwealth after the ouster of his power-mad sister Katherine.
- Ace Custom: Pilots a modified Fafnir into battle. His is not unique; a few Fafnir pilots that can be fought in Solaris matches can be seen using the same build, however, he's the only one seen using it outside Solaris.
- <Hero> Must Survive: An NPC variant; in every mission he appears as a combatant, "Peter Steiner-Davion must survive" is one of the mission objectives. Justified, because replacing Katherine with him as Archon was the reason you were hired in the first place, and it's not that big of a deal to begin with; he's enough of a badass, he's more likely to pull you out of hot water during a firefight, and his Fafnir, being an assault 'mech, can give and take a lot of punishment.
- Supporting Leader: For the Davion path in the latter parts of the game. You even fight alongside him in the finale.
Nondi SteinerSister to the illustrious Archon Katrina Steiner, who is Victor's and Peter's maternal grandmother, and a very high-ranked flag officer in the Lyran armed forces.
- Four-Star Badass: While her sister was known mainly for her political acumen, Nondi is a military officer through and through.
- My Country, Right or Wrong: Partly denial, partly nationalism, this is why she was loyal to her mentally unstable great niece Katherine (who fancied herself "Katrina"). She goes down fighting against you and Peter in the Davion path.
