If Sora dies when fighting certain bossesnote Shan Yu, Thresholder/Possessor, Shadow Stalker, Dark Thorn, Cerberus (story fight), Hydra, Volcanic Lord and Blizzard Lord (story fight), Storm Rider, Xaldin (story fight), Grim Reaper (first fight), and Xemnas (first Armored Controller fight)., there is a chance that King Mickey will appear and take over as the Player Character to give another chance to beat the boss. Once he fills the Drive Gauge completely from either dealing damage or using a special command, he can revive Sora to full health to continue the fight.
While Kairi and Naminé are escaping from The Castle That Never Was, Saïx and two Berserkers find them and attempt to recapture Kairi. Riku then appears out of nowhere to backstab one of the Berserkers and scare Saïx off.
In Kingdom Hearts: Chain of Memories, Sora is alone facing Larxene (having angrily told Donald Duck and Goofy to stay behind after they started questioning his trust in his memories), badly wounded after his fight with the Riku Replica. Just as she is about to attack him, Goofy's shield comes flying at her face, a spell heals Sora, and Goofy and Donald place themselves between Sora and Larxene, reminding Sora that they had promised to protect him and that they would always stick together. Cue asskicking.
The climax of Kingdom Hearts Dream Drop Distance has this happen three times in a row. Young Xehanort and Riku are squaring off over Sora's comatose body, with more time-traveling Xehanorts appearing around them. True to form, Mickey shows up and freezes the bad guys with a Stop spell — except Master Xehanort pulls a Villain Override on his younger self and has an all-out brawl with Riku. When Mickey's spell runs out, Lea shows up to stop Xehanort from possessing Sora. Before the heroes can escape, the Guardian grabs Riku and Mickey and tries to crush them...only to get squashed when Donald and Goofy teleport in using a star shard. Whew.
The beginning of Star Fox 64 features a Big Damn Heroes moment. The Star Fox team flies in and save Corneria from the invading forces of Andross' army.
Wolf O' Donnell gets one in Star Fox Assault when he saves Fox McCloud from a group of Aparoids.
Peppy sort of gets one during the cutscene before the final mission of Star Fox Assault when he crashes the heavily damaged Great Fox through the barrier blocking the team from entering the lair of the Aparoid Queen.
Actually, Slippy is about the only really important character who never got one of these moments individually in the series, which is kind of fitting when you consider that Slippy is probably the least popular Star Fox team member with the fanbase by a sizeable margin.
Red Dead Redemption has this happen as a gameplay mechanic. A man is being held up by roadside banditos? BANGBANGBANG! A scarred, grizzled man on horseback just took out three of them shooting from the hip. A man's wife is being lynched for being black? Thwip! The rope just got shot out. BLAM! All the racists got their brains shot out by a man in a poncho, walking calmly over to help the poor woman, holstering his shotgun. Being attacked by wolves in the middle of the desert? 4 rifle shots later, they lie dead on the ground, the poor man free to go home. Be it rapists, cattle thieves or stage coach robbers, John Marston will show up in the nick of time to stop them and save your life, before bidding you good day and going off on his next adventure. Best Rockstar hero ever? Survey says, yes.
The player can also choose to ignore these and, in some cases, even decide to help out the bad guys instead.
Story-wise, there's John saving rebel leader Abraham Reyes from execution and later Reyes returning the favor when the Mexican Army decides to betray him.
Subverted and lampshaded in Disgaea 2, when Beauty Queen Etna arrives just in time to save the heroes from being overrun by a neverending flood of zombies. She's actually downright annoyed that she's wound up arriving just in the nick of time, "like one of those 'heroes of justice' losers", and considers just letting the zombies finish you off before taking on the Big Bad — fortunately for you, the Big Bad is carrying the Villain Ball, and sics the Mooks on her instead of letting them finish you. Cue the explosions.
Played straight and lampshaded later in the game with Axel arriving with his flute to subdue the Rifle Demons (see the second page quote)
Skies of Arcadia's opening cinematic has the Blue Rogues board Alfonso's ship for what was intended to to be a raiding mission. Instead, it ends with Vyse and Aika rescuing Fina, before she was taken to Valua.
Later, Vyse, Aika, and Drachma sneak into Valua's lower quarter to rescue Vyse's father. They use the sewer system to reach the colosseum just as Dyne and his crew were about to be publicly executed. And they even make a show of defeating the executioner himself, for an encore.
After getting everyone safely to the sewers, Vyse and Aika split off from the group to rescue Fina, after hearing she was being taken to the Imperial Capital. So they snuck into the upper quarter to board the monorail and defeat the soldiers guarding her. But they get cornered by Galcian, who attempts to stop them... until Drachma shows up with the Little Jack, in time to save their skins.
In Tales of Symphonia, before facing Yggdrasill in Welgaia, all of the members of the party besides Lloyd apparently sacrifice their lives (via being caught in various traps) so that Lloyd may continue onward to face Yggdrasill. Finally, Lloyd enters the chamber in which Yggdrasill is waiting for the completion of the transfer of Martel's soul to Colette's body. Yggdrasill is shocked and extremely angry that Lloyd managed to reach him, and moves to kill him — but then a fireball from above stops Yggdrasill in his tracks. What do you know, the rest of the party didn't die after all, and appeared just in time to save Lloyd!
Tears to Tiara 2: The slaves and gladiators are trapped in the heartland of The Empire. They arrived at the base of the Alps to find no reinforcements and the Praetorians blocking any hope of exit, and resolved to go down fighting. As they are about to be wiped out, Hamil and Tarte burst through the glaciers behind the Praetorians, leading The Alliance, wiping out the Praetorians and saving the day.
Final Fantasy IV. After smiting the Calcobrina dolls, the group is confronted by Golbez, who promptly douses them with a paralyzing agent before summoning a Shadow Dragon to start killing them. Kain gets off lucky if he's in the air before the gas goes off and when the killing begins; Rosa and Yang are still screwed. Golbez happened to be hiding the Villain Ball in his robe at the time, as he takes a moment to bid Cecil farewell...a moment too long, as that's when Rydia and her Mist Dragon erases Golbez' Shadow Dragon and Cecil's paralysis is lifted via Unicorn Horn before the real boss battle begins.
As it turns out she's really good at these because she does it again in Final Fantasy IV: Interlude in almost the exact same way she did during the battle with Golbez. Just as the fake Rydia is about to utterly obliterate the party with Bahamut, the real Rydia shows up and blasts the imposter and Bahamut with her Mist Dragon. After a brief intermission the battle begins a new, but this time it's more of a curb stomp battle since this time you'll likely be using the very same power you almost got obliterated with.
Tifa made Cloud promise to save her if she was ever in a pinch, 'cuz she thought it'd be cool and said she always wanted to see it happen. She gets her wish twice: when Cloud arrives in time to save her and Denzel in Advent Children (at 2:58-3:31), and in Dissidia 012, where he shows up and fights Sephiroth to protect her. Tifa lampshades the latter incident in the following quote (at 1:55-2:08).:
Tifa: (to Cloud) "Thanks again for saving my skin. The way you showed up and fought that guy off... it was a pretty cool thing to watch. You were like a hero charging in to save the girl."
Final Fantasy IX has one during a cutscene in Disc 3. Eiko and Dagger (Garnet) are praying to summon Alexander and save Alexandria. The Big Bad decides this a bad idea, however, and proceeds to destroy Alexander, with Dagger and Eiko still on him. Cut to Zidane swooping in to save Dagger at the last second, and Dagger with tears in her eyes hugs him for being there. Aww..
Yuna is gettin' hitched to the Big Bad, Seymour, so the party comes charging in on an airship to crash the wedding, guns blazing, kicking physics to the curb—and all they do is get overwhelmed by the amount of guards there and ruin Yuna's plan to Send Seymour by giving him material to threaten her with—kill him and they die too. They all wind up arrested and imprisoned anyhow, though were it not for Yuna thinking on her feet, they'd be dead. Yuna herself manages to escape and then has to go into the dungeon and rescue them alone. So this is a vicious inversion of the Distressed Damsel too.
Played superstraight later, on Bikanel Island. When Tidus wakes up, he is attacked by a monstrously huge Zuu bird, which he must fight for a few turns on his own before Auron and Lulu turn up to help him out. Level grinding or abuse of Delay Attack can result in confusion, before Tidus defeats the beast before he is rescued.
Final Fantasy XIII has one in the city of Palumpolum. Lightning and Hope are surrounded by hundreds of PSICOM soldiers, with their commander reminding the soldiers how "l'Cie are not human." Just as Lightning's telling Hope to run for his life so she can pull a Heroic Sacrifice/You Shall Not Pass...a section of the nearby building explodes and Snow comes out swinging, punching out several soldiers near him, tossing a gun to new comrade Fang, and summoning Shiva to glaze the whole damn plaza over with ice which he proceeds to ride the Shiva-bike on as Fang rides shotgun. Badass. You can tell Snow doing this because he refers to himself specifically as a "Hero".
Later in Palumpolum, after Hope has forgiven Snow, Snow collapses from exhaustion and is almost immediately attacked by an enormous Sanctum war machine. Hope tries to take the thing on by himself, but it is almost impossible to destroy it. Once Hope is defeated, Lightning and Fang arrive and join the fight, with Hope revived.
During the cutscene between the Final Boss' two forms, Lightning, Snow, Sazh and Hope are all dead (or at least Cie'th), Fang is being tortured and resurrected by Orphan mercilessly, and all Vanille can do is stand around and watch. Suddenly, a massive blast of magic hits Orphan, and Fang's body (thrown from the blast) is caught by Snow, with Lightning, Sazh and Hope just behind him — readily forgiving her and asking her to stand with them and fight. Much badassery followed.
During the second trip through the Forsaken Fortress in The Legend of Zelda: The Wind Waker, Tetra pulls this twice — once to distract the Helmarock King and buy time to rescue the captives and again when Link is in Ganondorf's grasp...only for this attempt to fail and require another dramatic rescue.
A pretty ironic example, considering that she's the damsel and he's the hero. Well, she's an Action Girl after all.
It also happens in Twilight Princess, as Link gets confronted by a hoard of enemies in Hyrule castle, and suddenly BAM. Cavalry. Well, infantry, but same effect.
About halfway through The Legend of Zelda: Skyward Sword, Link gets help from Groose of all people. He helps him keep the Imprisoned sealed away, blocks Ghirahim's path to the past (albeit a doomed attempt), and even dive-bombs to catch Zelda. This is such an improvement in his character that you wouldn't recognize him if you started the game over.
In Hyrule: Total War Zelda I is about to get killed by Ganon's minions when Impa shows up.
Happens in every case of the Ace Attorney series at some point. Phoenix is ready to give up and your client is about to be declared guilty but suddenly...HOLD IT! Someone comes in with new evidence to save the day. The last case in the second game ends up boiling down to stalling until the big damn hero arrives.
The third case of the first and third games where Detective Gumshoe pulls this outside of court. Gumshoe's failed attempt at this in the fourth case of second game, and Franziska's pick up save off of this at the very last second.
It's subverted in Ace Attorney Investigations 2, where Franziska von Karma bursts into the room in case 4, delivering the news that the victim died from her head wound, not her stab wounds. Franziska's not happy when Edgeworth tells her they proved that five minutes ago.
Larry Butz's big save in game 1, case 4.
Gumshoe ends up saving Phoenix and Maya's lives just as much as the cases.
This trope occurs in Halo games several times, with Master Chief rescuing Marines, Johnson rescuing the Chief, Chief rescuing Johnson, Arbiter rescuing Chief, etc.
Halo 3 directly references the Trope Namer, as a character called Sergeant Reynolds, played by Nathan Fillion, states "Looks like we got here just in the nick of time. What's that make us?" Gamers everywhere immediately replied "Big Damn Heroes, sir!"
In fact, part of the ad campaign for Halo 3 was based around the beneficiaries of such moments reminiscing about the hero who saved them. You can see a couple of these ads here and here.
Cortana: "Admiral, tell your men to hold their positions. Reinforcements are on the spoke."
Admiral: "The entire fleet is engaged Cortana. With respect, what the hell sort of reinforcements have you got?"
Mission Log: "STOP DESTRUCTION OF HUMAN RACE...IN PROGRESS"
The Master Chief then proceeds to throw himself out of a rapidly decompressing launch bay on a space station into a pitched space battle in Earth orbit to directly assault a Covenant cruiser...alone
Master Chief's mere presence seems to inspire this, given the quote from Sgt. Banks in Halo 2:
Sgt. Banks:"When I asked for reinforcements, I didn't think they'd send a SPARTAN."
The Subspace Emissary of Super Smash Bros. Brawl has Sonic showing up just in time to prevent the final boss Tabuu from releasing a super attack on everyone. Also Ness and Falco get their Big Damn Heroes moment.
Meta Knight manages to save Lucas and Red/Pokemon Trainer from falling to their deaths (or rather falling to their trophycation).
Link, Mario, Pit, Kirby, and Yoshi get one as well, leaping off a cliff to come to the aid of some of the other heroes who're fighting off the Primids.
Every character gets one of these at one point or another. Fox bursting out of the wreckage of his Arwing to save Diddy Kong, Captain Falcon using his signature move to take out a ROB who's just annihilated Cpt. Olimar's pikmin team, Ike destroying a Subspace Bomb being carried by the Ancient Minister, this list could earn its own separate page.
Fire Emblem does this in every game out in the US (probably every game, period), generally as reinforcement to the story's lord showing when they are in a really serious bind. However on easier difficulties this often leads to the reinforcements needing AMAZING projection as they aren't as leveled.
The first example of the lord getting to be the "Big Damn Hero" is in Fire Emblem 7 (released in the states as Fire Emblem). Florina (a supporter to the tutorial chapter's lord, Lyn) arrives to the main team of heroes to tell how her Lyn and the castle are under attack, naturally the main team of the game go to save them.
Second example is in Fire Emblem 10, right when Lucia is going to be executed by the rebellion, The Greil Mercenaries in PERFECT Big Damn Heroes form all show up. What's great is that in the cutscene for their arrival, each one arrives saving another member of the party from being attacked. So any time the villains attempt a counter strike, they are instantly taken down. Making it a string of Big Damn Hero moments.
In Mega Man Battle Network 6 (6 being the last game) in the 3rd to last (the last 2 being past the point of no return) cutscreen in the game, the villans realize it is a better idea to take on the Kid Hero in the real world then in cyberspace, only one of these moments save Lan.
To be broader, Battle Network loves this trope such much that it has a Leitmotif for it.
Special mention goes to Protoman, who gets these moments all the time.
Laker from Super Robot Wars Original Generation actually plans this, he lets Elzam keep the Kurogane, and occasionally gives him mechs so he can have moments like these, and aid the Hagane, and Hiryuu Custom from the shadows. In Original Generation 02 the Hagane did this a lot in the early levels pissing off the Shirogane's captain Lee Injun, who was jealous of the Hagane.
Sanger Zonvolt seems incapable of entering a scene in any other method. These include, saving his former subordinate from Sanger's Evil Knockoff, using his signature move to kill an enemy outright in his first appearance in battle, and when fighting his Evil Knockoff, falling through the ceiling of a shelter designed to survive the end of the world, just in time to save the party.
Axel Almer and Alfimi both did this in OG Gaiden to play part in the Super Robot Wars MX prologue. When the Jetzt wrecked the Cry Wolves, and it got Foglia killed, Hugo fatally wounded and Albero is sure in to be their next victim, suddenly both of them arrive and attracted the Jetzt, giving Albero time to escape with Hugo.
An official Super Robot Wars Alpha 3 manga features this. After the Big Bad is defeated, Son Ganlong appears to take advantage of the Alpha Numbers' weakened state and finish them once and for all. At that point all the Alphas who didn't return in 3 show up to support their friends and dispense an almighty smackdown.
In Super Robot Wars Compact, Londo Bell comes to the rescue of Judau and Seabook in "A New Strength" and "Inside the Winds of Light". Judau in the former mission and Seabook in the latter mission
In the first Z game Kira Yamato as usual often appears out of nowhere in the Freedom to help your guys out, provided they aren't allied with Zaft. If you take the route where you are, he appears out of nowhere....to attack you instead.
There's another one as early as Stage 6. The Joule Team is attempting to stop the dropping of Junius Seven when the Mineva shows up with the heroes. Near the end, Memetic Beasts show up and surround the Mineva and attack the ship. When things look bleak, who does show up but Great Mazinger, who delivers a heaping serving of Thunder Break onto them!
2nd Original Generations gives us a Doozy: After spending several missions with the vast majority of the Steel Dragon Battle Group ends up Trapped in Another World, the game shifts to a few missions with the New Aggressors squad, along with Hugo and Aqua and D's Joshua Radcliffe. They find themselves surrounded in the initial moves of the Guest invasion, caught alone in the middle of the South Pacific. Suddenly, half the enemy force just explodes. Cue the Hagane and Hiryu Kai, back home from La Gias.
In Call of Duty 4 you both play as the Big Damn Heroes in several missions and are blown up by a nuke because of it in one outstanding, badass instance and are saved by the Big Damn Russians in the very last mission, though Gaz and Griggs would probably have preferred it if they could have arrived a few moments earlier....
In Modern Warfare 2, General Sheperd does this to the horribly outnumbered and wounded 141 squad led by Ghost and Roach, personally wielding a .44 magnum to fend off the Russian hordes.
In Earth 2160 we have one example. 3rd mission of Lunar Corporation campaign — two main characters (one of which was wounded in bomb explosion) are about to be torn to shreds by enemy mech with FOUR gatling cannons when suddenly three LC hover tanks shows up and without problem destroy above-mentioned mech.
The same line occurs in Mass Effect on Virmire, when you ride in to rescue the Salarian recon squad. They are less than impressed with your Bad Ass selves, wondering why the Council didn't send the army they asked for.
And speaking of Mass Effect, what about "It's the Alliance! Thank the Goddess!" One of the possible endings has the Alliance fleet arrive just in time to save the Council and its flagship, the Destiny Ascension.
There's also the moment when you have to save the quarian (Tali) from being assassinated.
Highlighted in Mass Effect 2, when Zaeed says of his loyalty mission "Get it out of the way so we can concentrate on being big goddamn heroes."
It's really all over the place in both games: Feros with the geth attack, Noveria with the breakout of the rachni, the Citadel itself with Saren's attack, the first time you encounter Tali in both games and her recruitment mission in the second, the Archangel recruitment mission, the assault on the Collector base (if you do it soon enough), saving the hostages from terrorists...there's a reason by the second game paragon Shepard is considered by everyone, including the bad guys, the Biggest Damn Hero in the galaxy.
Shepard's casual way of explaining why they're on Haestrom, saving Tali from a small army of Geth;
Shepard: I was in the neighbourhood... thought you might need a hand?
Mass Effect 3 also has plenty. Most of the time, your allies get their asses handed to them... until you arrive. Then your three-man squad quickly blows all the enemies away. Also happens in a cutscene during the attempt by Cerberus to take the Citadel, but only if Thane survived the previous game. Just as Kai Leng is about to kill the Salarian Councilor, we see a gunbarrel at the back of his head. It's Thane! He manages to hold off the highly-skilled assassin for a bit, despite living on borrowed time. Then again, who else to stop an assassin but another assassin?
The third game's Citadel DLC has a moment. Shepard (unarmored and injured) and his/her Love Interest are pinned by a shuttle full of armed mercenaries (including a Geth Spitfire). Just when things look bad, Urdnot Wrex (or James Vega, if Wrex is dead or hates you) comes crashing through the window a floor above with a war cry, and crushes/elbow-drops the shuttle hard enough to force it down onto the landing pad. He then leaps into the shuttle and starts beating the crap out of the very surprised mooks with his bare fists (and his armor-plated head), knocking them senseless and tossing some of them out the doors and over the edge.
Earlier, you come up against a couple of CAT-6 mercs while your health is down to 20%, you're not wearing any armour, and there's no real cover. Your LI — or Liara, if you're romancing someone who was Demoted to Extra (Jack, Miranda, Thane) or was a Mauve Shirt from the get-go (Traynor, Cortez, Kelly), or if you just haven't locked in your main-game romance yet — will show up and take them out in about three seconds with biotics, tech attacks, or good old-fashioned bullets. They will then be distracted by your butt.
In Metal Gear Solid 4, Johnny Sasaki, the resident Butt Monkey of the series, saves both Solid "Old" Snake and Meryl in the Middle East and Eastern Europe, and then saves Meryl near the end of the game. Johnny and Meryl then proceed to kick a lot of ass, becoming a Battle Couple in the process. Also Raiden, who would save Snake's life at least twice...the first time cutting off an arm to do so, then the second time appearing without his arms, his sword (Rule of Cool) first clutched in his teeth and then in his left foot.
And followed up by Henry during the final boss of the sequel.
Subverted multiple times in Metroid Prime 3: Corruption, wherein the bounty hunters show up just in time to reactivate a dead orbital cannon and nuke the Space Pirates' asteroid weapon — and then just before they can hit the Big Red Button, Dark Samus shows up and blows them all away, achieving a Big Damn Villain moment of her own.
And then subverted yet again, as Samus turns out to be Only Mostly Dead, hauling herself to the control panel and activating the cannon before lapsing into a month-long Convenient Coma.
This is perhaps the only recorded case where this trope is well and truly inverted.
Samus pulls this off herself in Echoes, if you look at things from the point of view of the Luminoth. The Ing were two rooms away from accomplishing their dominations. Two rooms. Then Samus turns up.
Probably the most classic example of the series takes place in Super Metroid. Mother Brain has gone One-Winged Angel and is beating the crap out of Samus who, by the end, can't even stand up. Right as Mother Brain is about to deliver the final blow, the baby Metroid that Samus sort of adopted comes in and drains a massive amount of energy from Mother Brain and transfers it, and the Hyper Beam, to Samus. After that, it sacrifices itself in order to give Samus time to recover and finish Mother Brain off once and for all.
Metroid: Fusion has a weird example at the end that parallels the finale of Super Metroid. Samus is one again on her knees and this close to being finished off by the Omega Metroid, and it's the SA-X of all things that shows up and saves her. In this case it's not because the SA-X wants to help Samus, but rather because it's compulsively attacking the X Parasite's natural enemy.
The World Ends with You has Neku and Shiki, in the third day, almost out of time. Then at the last second, Beat and Rhyme show up and finish off the "master of A-East." Since only one player needs to complete the mission to spare everyone from the threat of erasure that comes with running out of time, their action not only spared them, but also Neku, Shiki, and all the other players currently in the game.
Near the end of their week, Neku and Josh get a few chances to do this during a Taboo Noise rampage, two out of three of which you can skip over and the third one, oddly enough, forces you to save someone who is as good as dead even if you save him from the things.
At the beginning of the third week, Neku is the only player in the game after all the other players have been taken as his entry fee, meaning that he can't partner up with anybody and is completely defenseless. Just as he's about to get erased, Reaper Beat comes out of nowhere to form a pact with Neku.
In Mega Man X2, if X succeeds in retrieving all of Zero's parts from the X-Hunters, Zero will break into the Central Computer's core just before Sigma unleashes his Copy-Zero on X, then proceed to destroy the Copy himself and punch a hole in the floor for X to pursue Sigma, all accompanied by kick-ass heroic music.
At the end of Mega Man X3 either Zero or Dr. Doppler will arrive just in time to save X from the invincible Viral Sigma.
Mega Man X8 allows players to make a team of two characters to take on every level. In the last level in Hard Mode, however, one of them will be incapacitated by Vile going kamikaze. Later in the level, during the confrontation against Sigma, he gets the upper hand, and has the player in a choke hold (in a cutscene). Cue the other character swooping in to save his partner, and the battle resumes.
X returns the favor at the end of Mega Man Zero 3 when he and the three Guardians help Zero in defeating Omega once and for all.
But subverted in both Zero 2 and 4. In 2 you arrive to confront Elpizo, and he hasn't destroyed X yet. But as Zero dashes in, he's caught in a capture field and can only watch as X is destroyed. And in 4 Craft fires Ragnarok just as you reach the boss door.
At the beginning of Zero 4, the Caravan of humans that are fleeing from Neo Arcadia are being chased by Weil's forces, and just as the mooks descend on the Caravan, Zero arrives to save the day.
Gears of War: "Looks like we are the support, huh, Colonel?"
Earlier than that, when Marcus, Dom, and Rook- I mean Carmine are exploring the ruins of Ilima City and get pinned down by a squad of Locust, Cole pulls off a superb Big Damn Heroes by showing up and taking out the entire enemy squad by himself. "Nobody plays this game like me!", indeed.
Early on in Suikoden II, Flik and Victor show up just in time to stop the executions of the main character and Jowy. On your way out, you discover the main character's sister has broken out of jail on her own, and was on her way to attempt the same.
A variation in War Craft III. Arthas and the village have held the line as best they can, but finally the undead are proving unstoppable...and then Uther, with The Cavalry at his back, charges into battle. But despite his initial joy:
Arthas: Uther! Your timing couldn't have been better!
...he becomes defensive later, when he misinterprets Uther's admiration as disbelief that he was good enough to hold out so long.
In Half-Life 2: Episode 2, you try to protect a completely occupied vortigaunt and its barely-alive patient with two mauve-shirts and two busted turrets. By the last wave, it's the three of you and one working turret against dozens of Antlions. Then the last turret breaks down. You figure this is going to get unpleasant. Then, three Vortigaunts, who have been nothing but background filler until now, wander into the scene. Moments later, it's you, two mooks, and three Vortigaunts, against HUNDREDS of Antlions, all coming at once. And you know what? The Antlions never stood a chance.
Griggs said it best:
Griggs: Jesus! I've never seen the Vorts this PISSED!
Alyx gets a fine moment of her own in Half-Life 2 when she saves Gordon from the Metrocops early in the game. Then there's Gordon himself, who only hesitates to fling himself into alien dimensions and unstable fusion reactors if you, the player, make him.
It's made even more awesome when you hear snapping and the high-pitched whine from dead Metrocops.
And it decisively shifted the Vortigaunt's personality from fugly alien Magic Negros to definite badasses.
Half-Life 2 had its fair share of Big Damn Heroes moments like right before the climax of the game when Dog kills a squad of Combine soldiers using an APC as a weapon then goes flying through the air wrestling a Combine Dropship.
Tales of Phantasia offers a rather interesting example, wherein one character performs a Big Damn Heroes moment for the player characters...who immediately perform one back. Near the beginning of the game, the Big Bad Dhaos is unsealed, and Morrison casts a spell to send Cless and Mint 100 years into the past in order to save them from Dhaos. The two of them go on a journey (collecting two other allies in the process), and eventually activate another time warp to appear between Morrison and Dhaos, mere seconds after Morrison had sent them away. To the player, it took 30 or so hours of gameplay, but to the mentor and the bad guy, they appeared to have warped right back...until they proceed to kick Dhaos's ass, something they certainly couldn't have done when Dhaos first appeared.
In the fangame Mother: Cognitive Dissonance, you get two moments of this: When Alinivar's party is about to face off against the Greyface in the Pigmask recruitment center, both Niiue and Larice, the latter thought to be dead by the Greyface, burst into the room to help with the battle. Then when you start heading towards the end to defeat Giegue in the center of his mind as he becomes Giygas, two Niiues appear to keep your party topped on health and force Giegue to retreat further into himself in the Maelstrom.
In MOTHER 3, the end of chapter 3 has the party cornered by Fassad and his mob of Pigmask soldiers and tanks. They get a little worried after they manage to destroy one of the tanks, but it's not enough to make them back off. Cue Lucas showing up with his baby Drago friend, who promptly gets mocked, only to callits mother who proceeds to send the lot of them packing.
As a nod to the first Earthbound example, DCMC shows up to take out the remainder of the mob of Porky bots you fight near the end of the game once you've destroyed enough of them.
City of Heroes: Most of the missions involve you arriving just in time to save someone, keep something from being from being destroyed, or stop a villain's plan. The Trope Namer is actually referenced in one Task Force. The badge you get for defending the city's dam from three different groups of enemies is Big Dam Hero.
There's two in fairly close succession at the beginning of Valkyria Chronicles, the first where Welkin saves his adopted sisters life by clubbing an imperial soldier about to shoot her with a fence-post, the second moments later when the siblings get their dad's old tank up and running and perform a proper rescue of the town watch in Bruhl. Alicia even mentions 'Now you're my hero' to Welkin afterwards.
Lancer of Fate/stay night is king of this trope in the UBW path. Has his heart impaled, and then he kills the Big Bad of the last route in one attack. That's cool right? Heroic determination and stuff, nice from a guy who was just a minion. Only then Shinji shows up, and gets big damn heroed out as well, though not fatally. Still walking around and chatting sans heart, he lets Tohsaka go and burns the entire castle down.
Gilgamesh subverts it by turning into the next baddie. Archer zigzags on the 'hero' bit.
Rider does an unexpected one in Heaven's Feel, showing she's not as weak as she was in other routes.
Tragically subverted in Cave Story, wherein the BDH arrives moments too late to save the victim from being force fed a red flower, and is killed moments later when he tries to attack the villains in a rage. And then you have to Shoot the Dog.
Later played straight in the final, good ending, where you and Curly Brace are nearly crushed to death by a set of moving walls before Balrog the flying toaster, of all people, swoops in to save you.
In the last mission of Battalion Wars 2, Pierce has no fewer than 3 Big Damn Heroes moments: providing 3 Fighters to combat the air force; shooting down Kaiser Vlad's escape transport, rendering his obtaining the staff useless, at least until the next game; and giving Betty a ride on his personal Fighter to rescue her from being nuked by Vlad's usage of the staff used to call the satellite weapon.
MechWarrior 3, you have picked up two of your 3 available npc allies and are traveling across country to try and rendezvous with mechwarrior Keith Andrew, who you have been in contact with for much of the game.

The enemy responds by sending a massive force, and another from the other way, and there's an assault mech closing from the west, wait isn't that...
Alan Matilla: Can you read me, Damocles Command? Looks like you need a hand.

Its defenders are badly outnumbered, outgunned, and outmassed, and are verbally confirmed to be moments from suffering numerous losses.

As the player is confronting the lich who is commanding the Scourge ground forces in the area, the lich simply casts a spell that paralyzes the player and all of the NPC Alliance soldiers who are present. As the lich is gloating about his seemingly easy victory, Bolvar Fordragon shows up and instantly frees everybody from the paralysis spell. Although the player can help in the ensuing battle, their contributions don't really amount to much as Bolvar more or less solos the aforementioned lich by himself.
