Gappies, or Gappy Stus, are children Yukari gaps into Gensokyo, often because they have a power to unlock, because they have a terrible life in the outside world, or because they're The Chosen One to resolve an incident. However, we learn that nearly every single Gappy has gone corrupt and are then killed by the residents. It is unknown why Yukari gaps these children in or if there's a pattern in the kids she picks... There is an obvious pattern for Wish Fulfillment regarding why she picks the kids she picks. She has three primary reasons for gapping in children: to restore the peaceful ecology of Gensokyo by contrasting it with the heinous acts of the outsiders, to remove troublemakers from the outside world, and... well... since Yukari isa youkai...
We Have Reserves: As long as there are brats who want a quick-and-easy way out, there will be Gappy Stus.
During the climatic battle, when it's obvious that Brolli is about to die, Yukari tells Brolli she specifically picks kids that have no impact on the outside world if they were to go missing, and there's roughly an endless supply of them.
You Can't Fight Fate: Komachi eventually reveals to Brolli that Yukari gaps in children she absolutely know will end up causing a disaster. Worse, Tenshi's plan partly involves exploiting this to ensure Brolli causes the disaster while simultaneously trying to prevent it. Those who have said Screw Destiny like Vic and Brolli have only done so at overwhelming loss.
"He can't take my stuff from me! A man *is* his stuff! He's taking part of my manliness!"
Warning: This bio contains dozens of spoilers for both the story and Brolli's character arc.The Doomed Protagonist of Diamond In The Rough, who will die in three months of entering Gensokyo by Tenshi's hand. Before this, he was an Ordinary High-School Student who dreamed of an easy, carefree life. His dreams get answered when he is invited to Gensokyo by Yukari Yakumo, but it does not solve his laziness and self-centeredness. After growing tired of Reimu's Jerkass behavior towards Gappies, he learns stealing and destructive firepower from Marisa while allying himself with the Moriya Shrine. He also starts a heavy sexual relationship with Reisen, originally to get free medicine. As Gensokyo begins to fall apart, he begins questioning whether or not he's truly a good person or if he's just using others as a means to an end.In the end, nearly all of the factions in Gensokyo systematically betray Brolli when Tenshi causes an incident to make people realize just how much they really hate him. Naturally, Tenshi ends up killing him.
Badass Normal: During the incident, he briefly becomes this when he helps liberate the Kappa Valley from the fairies and holds off Tenshi for as long as he does.
Be Careful What You Wish For: Brolli eventually reveals he came to Gensokyo because he thought it'd be easier than living in the real world: in Gensokyo, he can gain infinite power and have his fears hypnotized away. However, by the time he's worn out his welcome, he realizes that even though he has everything, there's nothing much underneath all of his weapons and wealth. Then he wishes he could just go back home and live the life he took for granted, but by then it's far too late.
He also wishes to be the center of attention. Then, an incident happens where he is marked for death, and his allies will go as far as gunning down civilians to save him.
Celibate Hero: Brolli isn't phased by the fact he's surrounded by mostly girls, and he avoids any advances by Marisa. He's also rather freaked out about landing on a Reimu love pillow. Subverted when he meets Reisen.
Act 1note From when he enters Gensokyo to finding out his powers might destroy him.: His trip around Gensokyo jades him until he goes Drunk with Power. When he sees what happened with Arturo, he vows to be different from every other Gappy.
Act 2note From first meeting Reimu to winning over Reisen.: Although he has good intentions, he eventually starts losing integrity when he decides to gain more power by manipulating everyone he knows into getting him what he wants. His expectations are also becoming much more realistic than he was at the beginning.
Act 3note From denouncing his alliances to leaving Gensokyo: By this point, he is actually less of an intentional Jerkass and more of one by accident: he genuinely cares about the people of Gensokyo, and especially the ones who treat him kindly since he is now beginning to regret his decision of leaving his old life behind. Whenever something bad happens, he now takes responsibility for it. He is also less sure of himself and worried about who/what he can trust. When it becomes too much for him, he decides the best action is to run out on his friends and loved ones to save himself.
Act 5note From the battle of the Kappa Valley to his trip on the Sanzu River: In the grand finale, Brolli refuses to hurt Gensokyo any more than everyone else is and stands to fight to stop the incident. However, as the ensuing battle results in the utter breakdown of alliances, the pain of everyone he loves, and everyone betraying him, his will to survive ceases, and all that's left is to save the world he helped destroy. He sacrifices himself fighting Tenshi without relying on any powers or weapons. When Komachi gives Brolli his beret, he willingly tosses it into the Sanzu river and denounces the title "Colonel" Diamondback.
Ending: Brolli is now The Atoner, now selfless, humble, and sympathetic to others.
Despair Event Horizon: The story opens just as he's crossed it, assumingly because he lost to Tenshi. We later find out it's much, much, much, muchworse: his cruel and selfish actions to gain more power led to a nightmarish incident that destroys most of Gensokyo and kills thousands, he can't even use the powers he fought for because Tenshi spread a mist that disabled them, virtually everyone has systematically betrayed him in order to save Gensokyo, and even if he survives, the rest of Gensokyo will be waiting to kill him. His only remaining options are to defeat Tenshi and then destroy and enslave Gensokyo, or sacrifice himself and burn in Hell like the rest of the Gappies. Then, the rest of the ending just drives him further and further until there's nothing left of him.
Destructive Saviour: In that preparing to save people by looting Gensokyo for its resources has destroyed it.
Doomed Protagonist: In the first half, you're aware he's going to die in the end. In the second half, so is he.
Earn YourBittersweet Ending: In the end, Brolli's incident leaves Gensokyo in ruins, ruins several alliances, and (of course) gets him killed. However, his willing sacrifice to let himself die to save Gensokyo keeps it from getting any worse, Gensokyo has a chance to recover, and it's now willing to stand up to outsiders to prevent more tragedies like this. Plus, he gets to be reincarnated since, unlike the other Gappies, he finally learned. Granted, it's still very, very, very dark, but at least it's not as depressing at the rest of the series.
Flat Character: In-Universe. When Reisen asks him what he's like without his powers, Brolli cannot come up with an answer. Later, Aya tells him he mistakes his weapons and powers for personality, and if he were to ask himself, "Who am I?," he'd find nothing underneath.
Greed: Brolli's motto is that a man is his possessions.
He finally abandons his needs for power and things at the very ending after not only losing everything, but being forced to save Gensokyo with nothing.
invokedGod Mode Stu: Averted in-story, but Brolli's main goal is to become invincible and unstoppable. Brolli's quest to become invincible sparks the incident, he loses his powers, and ultimately dies.
Heavy Sleeper: Brolli tends to sleep whenever he gets the chance. The only time he can't sleep is his first night in Gensokyo, and with good reason.
Mean Character, Nice Actor: Both Spaztique and the real ColonelDiamondback make note that Brolli is just a fictional character. Unlike the selfish, lazy, existentially-troubled character, the real ColonelDiamondback is a nice guy with a great sense of humor, a hard worker, and a gamer (the term Diamondback itself comes from Team Fortress 2).
Messianic Archetype: Tenshi's plan is to turn Brolli into this to end the blind trust of gappies in Gensokyo. Shinki reveals that he will have to become this if the Gappy Era is to end in Gensokyo. In the end, Tenshi's plan succeeds: Brolli dies to save Gensokyo, and his death destroys all of those who blindly aided Brolli while rewarding those who recognized he was detrimental to Gensokyo, leaving Gensokyo to force gappies to help themselves.
Nice Hat: Brolli's beret. He finally throws it into the Sanzu river after his Despair Event Horizon. In the end credits, the hat rests at the bottom of the Sanzu river with others trapped at the bottom.
Nice Job Breaking It, Hero: Ends up being responsible for the disastrous climax, made even worse by the fact he makes several other character responsible for it as well.
Nominal Hero: Not even really a hero: he just wants to live a carefree life in Gensokyo... at first...
Not So Different: It's fairly obvious Brolli will just end up like the rest of the Gappy Stus before him...
Took a Level in Badass: In the ending, when he manages to fight alongside the characters, culminating in his grand finale battle with Tenshi.
Took a Level in Kindness: When he begins to realize coming to Gensokyo was a bad idea, he begins becoming more thankful to the people who help him out.
During the incident, after seeing the destruction he is responsible for, he does everything he can to save everyone else, even if it means putting himself in harm's way.
Tragic Hero: In the latter half of the story, Brolli wants to save Gensokyo, but he refuses to leave or give up on saving his friends. By not leaving when he had the chance, he is stuck in the middle of an apocalyptic battle he cannot win, and he still cannot save everyone. It is only after he knows everyone betrayed him that he willingly sacrifices himself to save the rest of Gensokyo, but by then, the damage to his close friends is done.
Trauma Conga Line: The entire incident: the entirety of Gensokyo is under attack, Brolli loses his powers and become virtually defenseless until having to throw his beloved swords, half of Gensokyo is out to kill him while the other half are gunning down otherwise-innocent people to save him, he gets caught in an unwinnable battle with one of his best friends, and finally he has to witness everyone in Gensokyo go through their own Trauma Conga Line or get thrown into the Sanzu River, and his only reward for watching is that he'll go to Hell. At first, he decides to man up and become the hero he wanted to be, but when the trauma simply doesn't end, he eventually crosses the Despair Event Horizon. And this is before he is forced to watch everyone else face their own Downer Ending.
You Can't Go Home Again: A Foregone Conclusion since he ends up dying in Gensokyo. Brolli wants to stay in Gensokyo, hoping he can make things work out, but by the time he wants to leave, he's been gone for so long that he's been kicked out of school, his parents have disowned him for running away, and his cat has died. He decides to stay in Gensokyo, right about the time Gensokyo is ready to make him leave by force...
The Gappy before Brolli, who went to Gensokyo solely to lose his virginity at any price. Ends up in a relationship with Yuuka, which later turns out to be rather forced on his end after accepting her bluff to kill the nearby human children. When the youkai hunters prove ineffective in killing him, Victor Chaos lulls him into a false sense of security and murders him. His soul is then sent to burn in hell.
Broad Strokes: Early on, in a cautionary tale to Brolli, Arturo is wooed by Yuuka and begins a romantic relationship with her, destroying children and getting away with it, only for the youkai hunters to stop him. Then, Tenshi reveals the beings of Gensokyo have never stopped a Gappy before: only Gappies seems to kill other Gappies. Worse, Arturo's relationship with Yuuka turned out not to be as consensual as it was...
One of Brolli's classmate's and Yukari's second choice for her apprentice. He is more typical of most Gappies: well dressed, craves adventure, and thinks the world revolves around him. However, he is refused by Yukari since Brolli is lasting longer than she expected, angering him greatly. Later conversations with Yukari reveal he wants to go to Gensokyo because he can't get what he wants in the real world.In the end, he replaces Brolli, obviously doomed to the fate of the Gappies before him, only now it won't be at the expense of Gensokyo.
Spoiled Brat: Has a room full of toys and other entertainment devices, but would much rather go to a fantasy world for fun.
Upper-Class Twit: Even more so than Brolli: his room has an arcade machine, a jukebox, and more.
Victor "Vic" Chaos
"You do *NOT* want to know where that noise is coming from, and I hope you never find out! But the fact you've been hearing it means you're just as screwed as I am...
One of Brolli's classmates who apparently knows about Yukari. He was invited to Gensokyo to kill Arturo after he had gone rogue. After killing him, getting revenge on an innocent Yuuka, and accidently burning the remainder of the human village's children with Mokou and getting away with it, he asks to escape Gensokyo, but Yukari tells him that he'll never recover. Ever since, he has been on a long mental downward spiral.Notable among the gappies in that he is a rare instance of a "good" gappy, although like every other gappy, his obsession leads to his destruction. His story inspires Tenshi to plan an incident to finally show the residents of Gensokyo what will happen if they continue fueling a Gappy's wishes.
Tropes associated with Victor Chaos:
The Atoner: In the end, his goal is to figure out why Yukari is gapping children over to prevent it from happening again.
Chekhov's Gunman: Appears multiple times early in the film, only to later reveal he was the one who inspired Tenshi's incident.
Despair Event Horizon: Crossed it upon killing the human village's children to get revenge on an innocent Yuuka and getting away with it. This causes Tenshi to plan an incident in revenge against the ones who aid a Gappy into self-destruction.
Subverted when Jack's stupidity makes him realize him killing himself is just what Yukari wants, making him no better than the other gappies.
Earn Your Happy Ending: What Yukari advises to Vic, despite already crossing the Despair Event Horizon. In the end, he's one of the few characters to end up with a completely happy ending: despite losing Brolli, Arturo, and his actions in Gensokyo, he leaves the nightmare behind him to recover in the real world.
Go Mad from the Revelation: Seems to have gone crazy after seeing Yukari. Actually, he went mad after killing his friend Arturo, accidentally killing a field full of children, and witnessing everything in Gensokyo.
Based on characters by the real ColonelDiamondback, but slightly retooled. They are incarnations of the sins of Brolli's past lives, sealed as far away from Brolli Diamondback as possible. By themselves, they are ridiculously powerful, but as a group, they are infinitely more powerful than any being in Gensokyo.
A wolf youkai who acts as the "heart" of the Diamondback beasts, idealistic and quick to protect Brolli at any chance. Ferin is the culmination of all of Brolli's previous incarnations' vanity, protecting Brolli's image.
"A key to power is the fear of loss, therefore threats are a legitimate strategy."
A dragon and the strongest of Brolli's beasts. Has the key ability to manipulate pressure, giving him the ability of both wind and fire. He is responsible for destroying one of the human villages since they were too close to one of his diamond mines. Hydrus is the culmination of all of Brolli's previous incarnations' wrath, tapping into Brolli's violence and need for domination.
Jerk with a Heart of Gold: Despite his mean behavior, he mostly does it to protect Brolli and the other beasts. It's especially apparent after seeing him hug Velupe while forever stuck in Brolli's dead corpse.
Two celestials who turn out to act as a Dual Boss during the incident. As the namesimply, Dokeshi is dressed in an outrageous multi-colored clown-like outfit and has the power to manipulate light, while Koshaku is a Gentleman Snarker with the power to manipulate decorative flowers.
Tropes associated with Dokeshi and Koshaku:
Dual Boss: Dokeshi's power to manipulate light works well with Koshaku's power to manipulate flowers.
