Hello again fellow trailblazers!
Today we're here to talk about Silver Wolf! This "alternate version" of Bronya who's now getting her release has quickly become a fan favorite, and so it's now the best time to cover what we know about her and what we can gather from Honkai Impact as well!

First of all, disclaimer:
The Honkai: Star Rail characters and Honkai Impact 3rd characters who have the same name and similar appearances, except for Welt Yang, are NOT the same person, but instead you may think of them as something akin of parallel versions of each other! I go into detail about this and how the Honkai universe works here!
Now let's get into it!
First, let's go over what we know about Silver Wolf in Star Rail. She's a member of the Stellaron Hunters, working alongside Kafka and Blade, but she seems moreso along for the ride and to have some fun herself. She's a very skilled hacker who can do just about anything, to the point where she's even gained the ability to alter reality through her "aether editing" abilities. She sees the world as her own personal game that she can edit and play as she likes due to this and her very easygoing attitude. She comes from the world of Punklorde, and now travels along with the rest of the Stellaron Hunters. Her hacking skills are so impressive that she's even gone up against, and matched, Screwllum of the Genius Society.
But what about her backstory?

Silver Wolf's Story

As a child, she was already addicted to videogames. She worked in a fast food restaurant, being the only employee there, and she had turned the basement into an arcade hall where patrons of the restaurant would come to play. There she played multiple games, including Pong, Battle Wheel 32, Geometric Wars, Odysseus and Star Cheetah, eventually beating all the high scores on all of them, her name becoming the only one on the lists. Having run out of things to do in the basement, and growing bored of the restaurant as a whole, she bid goodbye to the owner and left.
Using her special weapon, Prometheus, she created some virtual partners as modules to keep her company, as those who worked alone on Punklorde wouldn't last long. She tried to find a job, something that could excite her, but soon she realized that, even alone, nothing on the world of Punklorde could satisfy her insatiable need to continue to improve and "get a new score", as she would think of it. Becoming a legend among the people of the world, she was eventually approached by a group of people. A man, a woman, a metal humanoid and one other. She joined, leaving Punklorde to go across the stars with the Stellaron Hunters.
Though it's not a long story, we'll see that it actually brings some similarities to a certain character from a certain other game. This has caused much discussion among people discussing whether they are the same or not, and we'll talk about that now!

Bronie, the Haxxor Bunny

Say hello to Bronie!
Bronie, in the Haxxor Bunny battlesuit
Bronie is a character from Honkai Impact 3rd. She is a version of Bronya seen only in a certain Bubble World, who stars in a few different events, including the ongoing one at the time of writing.
Before we talk about her, let's define Bubble Worlds really quick:
The universe in the Honkai franchise is made up of different Worlds, represented by leaves on the Imaginary Tree. These are complete star systems, though it's unclear if Worlds can include multiple galaxies, just one, etc.
Bubble Worlds, also called Bubble Universes in HI3, are instead fragmented versions of these worlds. They can be made naturally if a World falls off the Imaginary Tree, in other words losing its flow of Imaginary Energy, which eventually causes it to lose its integrity over time, and disappear in the Sea of Quanta (the space between the different "leaves", that makes up the rest of the universe that isn't occupied by Worlds). They can also be created artificially, and can be as small as to encompass only a single planet, or even a single moment in time, fragmented off of a World to form a very small bubble that preserves only that moment.
Now that that's explained. Bronie comes from a Bubble World within the Sea of Quanta, which seems to encompass an alternate version of HI3's Earth. Specifically, Bronie lives within Arc City, a technologically advanced city which hides a lot of shady transactions, gangs and corrupt companies. Here, Bronie is regarded as a legendary hacker, involved with many of these shady dealings but always working alone.
Bronie prepares for combat
As you can see, she carries a pair of guns, known as Crusher Bunny 19C. She also controls drones, which help her during battle, for reconaissance missions and just for performing some general tasks when needed.
But let's talk some about her story. As I've mentioned, she lives in this Bubble World's version of Arc City. Here, she works at a bar known as Raven's. This bar is named after its owner, Natasha Cioara, also known as Raven. (And yes, this is another version of HSR's Natasha, we'll get to her another day). She's also friends with a well known idol within Arc City, TeRiRi, this World's version of HI3's character Theresa.
Bronie mocks TeRiRi
Together, they infiltrate the Heliopolis Park, the main structure of Arc City, in order to grab a key that she had heard about in some intel. This is the key to the Light Curtain, a sort of barrier keeping Arc City separated from the rest of the world.
As she finds the place where this key is being kept, she is stopped from getting it by a mysterious ninja.

Bronie is eventually able to escape along with the key, and her and TeRiRi retreat to Raven's. Here they meet with Cioara, who shows her worry and opposition to Bronie's work as an independent hacker. With all the gang activity and powerful people out there, working independently is not only an inefficient way to make money, but can also get you killed very easily. To show her disappointment, she goes so far as to call Bronie by her real name, Bronya.
Cioara scolds Bronie
After revealing that she was able to take the key, Bronie runs away as she wants to avoid confronting the owner of the bar, and TeRiRi follows behind her. Here it's revealed that Bronie herself was part of the Taixuan gang, but she left in order to expand her horizons and eventually leave the city.
Their talk is interrupted by Gray Serpent, the one who sold Bronie the Heliopolis Park intel and a member of the Snake Eye gang. It seems the leader of this gang wishes to speak to Bronie, and so they follow him. She is led by an "introducer" named Rita, but she quickly figures out that she is, in fact, the leader she is supposed to meet.
Bronie and Rita
Snake Eye has in their possession another key to the Light Curtain. Three keys in total are needed, but the gang does not wish for the Light Curtain to fall, instead wishing to keep all the inhabitants of Arc City inside where it's surely safe. Therefore, Rita refuses to give the other key to Bronie, and attempts to take hers as well.
After a battle, Bronie comes out as the victor, and Rita gracefully hands over the key. However, Bronie also figures out that she had been holding back. Rita reveals that she lost on purpose to create a story and give Bronie credibility, and warns that Snake Eye is nowhere near as powerful as the holders of the other two keys, Heliopolis and the Taixuan gang.
Back in their hideout, Bronie and TeRiRi read some of Bronie's manga while they analyze the key. In one of them, TeRiRi reads about a samurai type of character who comes from a parallel universe. This seems to spark something in Bronie's mind, but she quickly brushes it off. Bronie finds a surveillance video of the ninja that attacked her underneath Heliopolis Park, witnessing her super advanced weapons and armor and her swiftness in defeating enemies.
The girls bring the fight to Taixuan gang in order to retrieve the final key.

Meanwhile, Bronie believes she's figured out the mysterious ninja, believing she is from beyond the Light Curtain, or more specifically, that just as the villain from that manga, she is from a parallel universe, explaining her advanced technology and powers.
As they continue to mow down the opposition from the Taixuan gang, they eventually meet with its boss, Big Sister Fu Hua.
Fu Hua, leader of the Taixuan gang
Bronie challenges her to a match, just the two of them one against the other, something that hadn't been seen ever since Cioara had come to the Taixuan gang and challenged Fu Hua herself, with the prize on the line being taking Bronie away.
When they arrive at the arena, Fu Hua instead reveals that Bronie will be fighting Cioara herself, to the death. Since they both want to stop her from leaving, Cioara agreed to be the one to fight her instead. Though Bronie puts up a good battle, Cioara is able to overpower her and push her to the edge of the arena.

However, Bronie uses her drones to get herself out of this situation. Even if she cannot move, they can, and she blasts Cioara away. She reveals that the first shot had an anesthetic, and that she had knocked Cioara unconscious. Fu Hua reveals that she never had the intent of keeping the key from Bronie, and had already given it to Cioara as payment beforehand. Bronie and TeRiRi return to Raven's, carrying the unconscious Cioara.
After Bronie and Theresa have a conversation about how much Bronie's grown, she decides to leave Raven's and go to look for the Curtain's core and finish this mission. With the blessing of both Cioara and TeRiRi, she prepares to go.
Bronie's final thumbs up to Raven's
She finds the Curtain's core, but is stopped by the ninja from before. She reveals that she had been after the core all along, and that Bronie had no use for it anyway as her goal simply required that it be removed. Bronie concludes, then, that the core must have another purpose, and thus decides not to hand it over to the ninja for free. As they battle, Bronie is able to set herself up and eventually is able to switch positions with the ninja, holding the core and placing herself closer to the exit. As she escapes, she triggers the security system to keep the ninja held up.
Bronie prepares to leave Arc City, but the ninja finds her waiting at the northern exit.

She decides to give the core to the ninja, but not without a price: she wants the ninja to take her to the world where she comes from. She refuses, as she says she cannot do it, but she agrees to teach Bronie how to leave the world she's currently in.
Finally, it's revealed that the Light Curtain core is something known as an Ether Anchor. The assassin, whose name is Kasumi, was tasked by a mysterious individual to retrieve it. Meanwhile, Bronie is able to leave the bubble universe in which she lived and land in a place called the Hyperion. Though this isn't important for the story we're telling here, Bronie's world is part of a greater network of bubble worlds, addressed in Honkai's events to create a story called the Captainverse. I won't go into further details here about this, as it's not too important, but from here on, Bronie continues to travel to different bubble universes, including the one from the currently ongoing event in Honkai.

Silver Wolf vs. Bronie

So now we come to answer the question: Are Silver Wolf and Bronie the same person?
If you've read the story of both, it should be pretty clear that the answer is no. However, it's also clear to see their similarities. Both grow up in a world with technological advancements, working in a barestaurant as its only employee, while also being very fond of technology and related culture. Both are incredible hackers of great renown who go around fighting against big gangs and people from the city while working alone, and both wish to leave their worlds after becoming bored, both achieving success in the end.
However, it's clear that Bronie's world is not Punklorde, and it's clear that Bronie's travels to different bubble universes is not the same as Silver Wolf's travels to different worlds with the Stellaron Hunters. They are still similar, but not the same, and the inspiration is more than clear to see.

The other Bronyas

To finish off this post, I'd just like to address the multiple variations of Bronya along different HoYoverse games. Alongside HI3's Bronya, Bronie, Star Rail's Bronya, Silver Wolf, and Gun Girls Z's Bronya, all of which are very different (though GGZ's Bronya and HI3's Bronya are the closest in character), there is also one more "Bronya", which may confuse some people if they see her.
The \"other Bronya\"
This... is not Bronya. If you don't know her (or well, it), you may be inclined to believe so. Yet even within Honkai's characters this is not counted as a Bronya. This is Prometheus. It is not a human, but instead an AI created by the Previous Era of humans that lived 50,000 years before the current civilization of Honkai Impact's world. The Previous Era and Current Era of Honkai share many character equivalents, and thus it's assumed that Prometheys is supposed to be the Previous Era version of Bronya.
Another detail you may notice here is that Prometheus shares a name with Silver Wolf's intelligent weapon! This makes the Bronyaverse go into an even tighter circle!

Conclusion

So this is it! I'm releasing this on Silver Wolf's release day, so there may be some details that can be taken from her companion quest or some other source I haven't been able to check out yet, and I'll edit the post to add such information if necessary! As always, please correct me if you find something wrong, and make suggestions for which character I should do this for next! Luocha's will come on his release day, so anyone else is fair game, as long as they have a Honkai Impact counterpart!
That said, I want to thank everyone here for reading this, and hopefully this has given you a deeper understanding of Silver Wolf, or at least of her inspiration, Bronie! If you've already pulled yourself a Silver Wolf, hopefully you'll enjoy her, and if you haven't, then may all your pulls be blessed, and may all Silver Wolf wanters be Silver Wolf havers!
