MASTERPOST: Blake's Captain Scarlet and the Thunderbirds AU
Hello and welcome to my main AU! The CSatT AU is the setting where I write almost all of my fanfic for Thunderbirds and Captain Scarlet. It's essentially just me blending together Thunderbirds TOS & TAG, and Captain Scarlet OG & New, into a single cohesive setting. Some Stingray is also here but pretty much only for the purpose of clowning on Troy Tempest.
In order to keep track of everything I'm gonna be real annoying and go point by point on all the little idiosyncrasies I've built up throwing this setting together. I will be going over;
- Timeline
- State of Canon Characters
- State of Original Characters
- State of Technology
- How Psychics Work
Sounds like a lot to get through! But I promise it isn't too much. It's just me trying to add structure to an inherently unstructured mess that I fully understand in my own brain but find very difficult to explain concisely 😅
Timeline
The AU starts In early-mid 2068, the year that the OG Captain Scarlet and the Mysterons takes place in. Specifically, it takes place not long after the episode Spectrum Strikes Back. In this setting, International Rescue have been in operation for about two years, and all of TOS is assumed to have happened already. For the most part, the introduction of OCs to the space won't impact subsequent OG CapScar episodes much, with at most my own Spectrum characters running around doing their jobs in the background. There will be a couple of exceptions, but I'm keeping those to myself for later 😈
State of Canon Characters: Spectrum
For the Spectrum cast, it is pretty much the personnel from the OG show, with a couple of caveats; the side characters from NCS are here under different but matching codenames (e.g. NCS Magenta is Captain Fuchsia. Pat's beefing with him), and Lieutenant Green is a trans woman.
State of Canon Characters: iR
For Internation Rescue, I'm being MUCH more annoying. Here we have TOS Blond John and Ginger Gordon, but also TAG Black Hair Virgil, because I love them. Scott is a pretty even blend of both versions, and Alan is like 80% TOS but I've stolen a few design quirks from TAG (also he might become a woman at some point). Jeff is still in the picture because of the TOS base. TAG Brains is here alongside Tin-Tin and her dad, with the the Kyrano family being Chinese Malaysian. They moved to the UK when Ren (Kyrano's given name!) and his twin brother (😉) were young. I've also mixed up everyone's image colours because it's my AU and I get to do what I like, so it goes;
Jeff - Steel/Dark Grey
Ren - Silver/Light Grey
Scott - Light Blue
Virgil - Forest Green
John - Lilac
Gordon - Yellow
Alan - Red
Tin-Tin - Turquoise
Brains - Orange
Larkin (OC) - Indigo
Morgan (OC) - Black
I like that in TAG Jeff had the grey belt before Scott so for me that's like, the leader of iR. Ren gets light grey because he's officially second in command!
State of Original Characters
I have, I must confess, a compulsion to create a demonic number of OCs - you need only look at my blog to see this. But as with canon characters, some OCs are more prominent than others. Most of my OCs are Spectrum personnel, because I started working on this fic as just a CSatM fic before I began besieging the setting with Tracy Men.
The de facto main character for the early, Spectrum centric portions is Nogami Riku AKA Captain Sable. They are part of a wave of new personnel specifically recruited for the war against the Mysterons. Through RIku and the other newbies I want to interrogate how I think Spectrum functions, how they deal with non-Mysteron threats, and the ethical struggle inherent to drafting new blood into a war that's almost impossible to win.
Some of them are more fleshed out than others, but throughout my work you will see references to;
- Captain Sable (Nogami Riku)
- Lieutenant Yellow (Antonina 'Tosia' Kędzierska)
- Captain Teal (Calais Manousakis)
- Captain Indigo ("Basmat")
- Sonata Angel (Hazeema Rizvi)
- Toccata Angel (Tien Anh Mai)
- Requiem Angel (Davi Ayres Zeferino)
As for iR, only two OCs of mine have found their way there so far, and even they have at least some interaction with Spectrum;
- Larkin Carver-Grey
- Morgan Riesner
Larkin is a victim of Mysteronisation who inexplicably woke up as themselves again like Captain Scarlet himself. They don't want to join Spectrum so they end up in iR (who are in-the-know) and their struggle to integrate is the subject of a whole fic. Morgan, meanwhile, is set up to be one of two protagonists for a planning-state Psychics plot I want to do in the later part of my timeline, around late 2069 into 2070 if my dates stay consistent. The other OC for that is Silver Avalos, another powerful psychic found by Spectrum during their investigations. They aren't so easily categorised and interact with iR and Spectrum pretty equally.
State of Technology
Here is where things start leaning more towards the reboots. In my AU I basically take the efforts the newer shows took to modernise all the tech and apply it to the TOS base I'm working on, either presented as-is or as constant iteration by Brains/Spectrum's R&D Department.
I'm still more comfortable with OG Scarlet's terminology, e.g SPVs are still called SPVs but they function more like NCS's Rhinos. All the new Spectrum vehicles introduced in the CG show are present as well. This is not just because I am desperate for Riku to ride around one of those sick as hell bikes from NCS, what are you talking about?
The Thunderbirds are presented as their TAG versions, with all the extra functionality they have being explained as Brains constantly updating his own designs over the last 2-3 years of iR's operations. Because if that man isn't busy working on something he starts scaling the walls of the villa.
How Psychics Work
Before we begin: This part of my AU is still very much a work in progress so it's subject to change and updates as I continue writing fic and coming up with new ideas. A lot of it is still up in the air at the moment.
In this AU, low-level ESP is a known condition that can be managed and easily lived with. It's rare, but not terribly rare, and in most cases usually just manifests as an overly powerful empathetic sense, or far above-average memory retention. Stronger forms do exist but by and large, dramatic powers of telepathy or "mind bending" capabilities do not naturally occur without focused training, and it's still a point of contention if physical space manipulations such as telekinesis are even possible.
One lesser known psychic phenomenon is the psychic pair bond. Psychics can, with practice and focus, form low-level permanent bonds with each other, usually in pairs or groups of three (any more and it starts to become difficult to manage) and through these bonds, the participants can share their powers with each other. Alongside training, and carefully sliding the scale of power back and forth between them, psychic bonds can become incredibly powerful, but it is not without its dangers. If one part of a bond dies, and their power was being shared with another bond member at the time, that power is permanently shunted to the remaining psychic. This can cause neurological issues from the psychic having to store the increased power on their own, and deep psychological trauma from losing their bond. The best way for a broken-bond psychic to manage this is by forming a new bond with another psychic to help shoulder the burden, but this can be an emotionally taxing endeavour for all parties involved.
Psychic Cold War
Preceding and running alongside the last global conflict at the turn of the 2040s, a secret psychic cold war was being waged. Governments across the world were secretly funding research into human psychic capabilities, naturally for military application above all else. Ren Kyrano and his twin brother were natural psychics recruited into a secret programme called ESPR, which was studying the applications of psychic pair bonds. As twins, the Kyranos made an excellent pair bond who excelled in their training. Eventually, however, they would turn on the organisation that "created" them and, with the help of one Jeff Tracy and a few others, would set in motion the downfall of ESPR and several other psychic war projects across the world. Cleaning up the aftermath of the psychic cold war is still being done to this day, with a lot of the work falling on Spectrum. Many of the scientists who worked on these less-than-ethical experiments would go to ground to avoid prosecution, only to be found later with the discovery of Morgan, a powerful psychic created from forcibly engineering pair bond death to give her the capabilities of several trained psychics.
Origin of The Hood
When the inevitable falling out occurred between the Kyrano brothers, Ren used all his strength to forcibly sever their pair bond, having to shunt all of his own psychic powers away for it to work. This left Ren with at least some amount of neurological damage, the loss of most of his capabilities, and the belief that he killed his own brother. In truth, the man who would become The Hood survived this incident and managed to escape, having taken on all of Ren's powers. This is why The Hood's mind manipulation in TOS is so potent; he's running two psychic soldiers' worth of power. It's also why Jeff and Ren never clock something else is going on with the latter's collapses and other health issues. That sort of thing isn't entirely uncommon with Ren, as he's been living with the consequences of his brother's "death" ever since.
And that's all I've got for now! I'll be coming back to this document regularly with updates, and perhaps links to other posts. I'll also put a link to this masterpost into my pinned post for ease of navigation. If you read this whole thing, congrats, you're one of my favourite people 🥰
