I HAVE A THEORY! And this is a theory regarding the newest character of Honkai: Star Rail, the rootin’ tootin’, flamboyant, brash, and trigger happy space cowboy of the Galaxy Rangers—Boothill! This will be posted on both Tumblr and AO3 for those who do not have either or for easier access! By the way, this theory contains mentions of leaks and in-game content, so if you don't want to get any spoilers, I advise not to read this theory at all.
For starters, I will admit that I haven’t played Honkai: Star Rail in a while due to…whatever reason I had, and one of those reasons was because of Twisted Wonderland! I was playing that for a while—still am—I was having a blast insulting Ace and having aneurysms over the students’ antics and methods of breaking people out (I’m lookin’ at you, Rook). It was great! Then, Star Rail showcases two new characters on their Twitter page for their newest planet known as Penacony, one of them being Boothill who a lot of people were upset with due to them wanting the characters, Sam and/or Firefly who unfortunately met her demise in the newest update, and…well, I fell head over heels for him and started saving for him (122 PULLS WITH 20 PITY BABY BUT HE’S MY FIRST FEATURED CHARACTER SO PRAY FOR ME). I kept up with leaks because I could care less about gameplay, stat kit, and character lore leaks since that’s the interesting part and helps me figure out if I want the newest character…like my Al-Haitham theory which did not age well, this theory about Boothill does stem from exhaustion from not sleeping, but I feel like this is a more coherent and sound theory than the last, and I have to say that I have to take this with a grain of salt—and I advise the same for you—because it’s merely a theory. I can be wrong on certain things, but without ado, I’ll start with what really feels like the backbone of this theory, and that is Boothill’s name: Boothill.
So, just to give a little context, prominently in Asian media—most notably Japanese and Chinese entertainment from what I’ve seen as I played HoYo games and watched a lot of anime—characters tend to have name pun which correspond with their personality, physical design, talents, etc., to give people a little laugh and be like, “Ooooh! I get what they mean!” For example, Zhongli, in HoYoverse’s most popular game, Genshin Impact, written as 钟离 in simplified Chinese, is a pun of his departure—his retirement—as Rex Lapis: 钟 Zhōng being a homophone for the word for “clock” as it’s spelled exactly the same, while 离 Lí is a common word for “leaving” or “away”. Putting it together, it can be taken as “time of departure/leaving” or “off the clock” which foreshadowed Zhongli stepping down as Archon of Liyue.
With that knowledge in mind, I looked at Boothill's name and decided to Google it because I knew it was a pun of some sort! My only thought was that his name could have been a reference to a western (cowboy) film I never heard of which, to me, made sense as Boothill is modeled after stereotypical cowboys, and HoYo loves pop culture references with the Genius Invokation TCG which is a reference to the ever-so-popular card game, Yu-Gi-Oh, and how March 7th and Caelus made a reference to the movie, Fight Club, when the Moles were talking about the first rule of Fight Club…never talk about Fight Club! So, I thought Boothill was a nod to an old movie!
…No! A lot of people have already Googled it, but for those who probably don’t know, Boothill’s name comes from a burial grounds for gunfighters—with headstones engraved with the gunfighter’s name or “unknown” if the identity of the person has not been found—in the Old American West called a Boot Hill, and that name derives from the phrase “those who died with their boots on”, meaning that the gunfighter died rather violently. I did see someone say that the phrase could also mean that they were hanged, and that part is correct as the context of the expression changed in the early 19th century. However, I don’t believe that Boothill was hanged—although it is a possibility that I will keep in mind! Again, I have to take this theory with a grain of salt so I don’t die on that hill again, but seeing Boothill’s situation that he’s metal and wires from the chin down, he most likely died in a very extreme battle in the past since the only thing human about him…is his head!
His body must have been blasted to oblivion to where it was beyond saving, beheading him from the impact of whatever and whoever killed him. Now, some people may think that they probably just beheaded him or he was shot multiple times in the chest: other possibilities I will keep in mind, but that would mean he could have resulted as some kind of Frankenstein instead because if the body was still there, the Interastral Peace Corporation or IPC (the people who rebuilt Boothill) would use that since he has things to salvage like a heart or liver, etc., yet if we look at another Star Rail character named Luka who hails from the Underworld, he is missing an arm which is replaced with a mechanical one. That is because Luka saved a child in a fire involving a monster possibly from the Fragmentum, and his arm was chopped off by the ax the monster wielded, giving him the prosthetic he has today. So, if we compare Luka to Boothill in terms of how bad the conflict in Boothill’s past was, Boothill lost too much of his body from the chin down for the IPC to even save, leaving him with a full body prosthetic.
Now, the question that we have…why was Boothill killed? Who could’ve had such a grudge against him that they killed him off so violently? Well, that is where his Light Cone description comes in. Let’s focus on the middle of the description where it states:
“Some cruel memories resurfaced as the unforgettable hatred turned into a weak light in the darkness.”
The Light Cone entirely describes when Boothill was regaining consciousness and how he felt while briefly in a limbo before being greeted by a doctor in the IPC. What sticks out are these “cruel memories” and this “unforgettable hatred” that he has which calls back to what happened before he died. I’ll lead into this with another point I have to make this make sense a little bit: Boothill is a bounty hunter. Why do I think this? Well, we get a glimpse of this in-game in the newest update of Star Rail where Black Swan answers the phone to a mysterious Pathstrider of the Hunt who is part of the Galaxy Rangers (a gang who “swore to punish the wretched by any and all means”) who is tracking down Acheron, ready to kill her for reasons unknown as of right now: that was Boothill who has been confirmed to be a Pathstrider of the Hunt along with him being a Galaxy Ranger as he calls Acheron an “imposter” who is also a Galaxy Ranger, most likely hinting that Acheron is going undercover and infiltrating the group. We also know it is him from his line, “My bullets will find you”, since he is a gunslinger with a bullet motif on his hat and actual bullets around his waist and one hanging from his left ear.
Going back to the point I made, he’s obviously smart with pinpointing someone’s location such as Acheron’s and having at least some information on her like her being an Emanator. His Path, the Hunt, is said to “admire determination, ruthlessness, and tenacious behavior”, which fits Boothill’s Light Cone description as well as his possible reason for his alliance with the Galaxy Rangers and why his finger is ready to shoot Black Swan if she was an ally of Acheron stating to “get [her] forehead clean…and wait for [him]”. A bounty hunter would have to be ruthless with their target, showing little to no emotion as they are the person they are after, the person who wronged their client or the bounty hunter themselves, and it is obvious that Boothill is determined to gather any info from Black Swan to continue his hunt with Acheron.
Now, with that in mind…Boothill had to have been a bounty hunter in the past who was wronged as he had “cruel memories” returning to his mind, and he had anger in his heart that was weakening but helped him return to the living world. If I were to guess, he may have had a loved one who died at the hands of someone else and gained the skills to become a bounty hunter in his previous life to hunt that person down because he had “unforgettable hatred”, and that had to be at a level where he couldn’t let go especially if he had “cruel memories”, and those could probably be that he watched that same loved one get brutally tortured and/or murdered in front of him. As to who the loved one of Boothill could have been, it could have been anyone: his father, his mother, a sister, brother, a best friend—Unfortunately, we do not have the information to determine that for sure, but I truly believe that it could be someone he was very close to that was tortured and/or killed for, again, reasons unknown.
From what we gathered in the leaks and what HoYo has already established, it was the IPC that brought Boothill back with unknown intentions, but to me for this theory, it’s because of his skills as a bounty hunter since he must have been the best hunter wherever he came from. However, Boothill has a new grudge against the IPC as the his reveal information stated that, “His flamboyant and brash actions were all to draw the attention of the Interastral Peace Corporation — the target of his revenge.” The man is very flamboyant as we can holler back to his Ultimate, his skill…the freaking JoJo poses—
—(somebody in HoYo is a JoJo fan—IT'S BECOME INCREDIBLY CLEAR NOW) so I can see him causing havoc and being flashy to purposely attract their attention so he can properly get his revenge on them due to them making him into a cyborg which he isn’t happy about.
However…if I go back to the Light Cone description…at the very end, it said that Boothill “would no longer live for himself.” Sounds a little strange, doesn’t it? Here he is greeted by the doctor that saved him, and he’s clenching his new iron fists (literally speaking) because he knows what the IPC’s intentions are. If he’s no longer living for himself, that doctor would most likely have a sadistic tone when he welcomed him back because they experimented on him, testing him and his new body and using him for unspeakable things against his will, and why do I believe this?
Think back to Boothill’s gameplay and the leak of his gun’s range. That could be a reason, and a way I can describe it is by using Bucky Barnes, a.k.a. the Winter Soldier, in the MARVEL franchise. In the movie, Captain America: The First Avenger, Bucky was believed to be killed during a fall off a hijacked train in WWII in an attack against HYDRA, a sub-Nazi group led by the Red Skull, Steve becoming devastated by his best friend’s death. However, in Captain America: Civil War, it was revealed that Bucky was actually brainwashed, gaining a prosthetic arm (like Luka), and became a Super Soldier under HYDRA as they experimented to revive Dr. Erskine’s research for the original Super Soldier serum. Plus, HYDRA knew of his friendship with Steven Rogers and that Steve was alive but was going to expose S.H.I.E.L.D. for their lies, making him a threat. So, they trained and used Bucky as their line of defense since he was the only successful experiment that remotely compares to Captain America in strength and combat.
Because of Boothill’s skills in gunslinging, the IPC possibly saw this as an opportunity to have an effective line of defense in case something were to happen in their facility or if there was someone they needed to eliminate; they would have Boothill who had those qualifications to be their guard dog, but hearing how Boothill talks in-game for the first time, you could hear a hint of insanity in him as he keeps insisting that he will kill Acheron and Black Swan with lines such as “My bullets will find you”, “you best find a casket store on Penacony, and ask the owner to reserve a good quality casket for you”, “I’ll leave a round for you, so get that forehead clean and wait for me”, and “Are you askin’ me to write your will?” He wants to kill anybody who hurts him, still having that anger. That must have been how he felt when he was trapped in the IPC facility, going through experiment after experiment that broke him to the point that he couldn’t take it anymore as he is still human; he still has emotions and a mind of his own despite being 90% iron and wires.
Boothill knew, from the sound of that doctor’s tone, that he would be seen as their Super Soldier, a little toy they could dispose of if he was deemed useless; he was nothing but a heartless, soulless object to them which most likely broke him. Boothill has calmed down since his possible escape from an IPC facility and killing people in order to have a successful breakout, but he still has that pain inside his heart because of the possible abuse he faced that he’s trying to protect himself from being betrayed or used again which is why he’s so expressive and flamboyant.
He wants to live for himself and show the IPC just how human he was. However, he’s still showing off how strong he is as a warning to others of what he can do to them if they ever crossed him.
Now, I cannot stress enough that this is just a theory (A GAAAAAME THEORY), and I have to take this with a grain of salt because there is still a lot we don't know about Boothill regarding his past or his relationship with the IPC. Heck, a friend of mine and I believe that Boothill may not actually be his real name, but there's no evidence of his real name to even prove that point. This is all speculation, and what I gathered and thought about using any resources I have at my disposal to produce this, so please—for the love of the QUEEN OF HEARTS HERSELF—do not take this as actual, confirmed, or leaked information on Boothill's backstory since there are many unanswered questions. For now, I'll stick to what I got until Boothill is finally released!
And hopefully not die on that hill like I did with Al-Haitham...
