And ofc Goku gets beat by a tiny laser beam when hes SSGSS, so... yeah.

Arcosians are not native fighters like the Saiyans were in canon, though those that do fight tend to be stronger on average on account of discipline and training. In fact, you're more likely to see an Arcosian running a market stand than in the middle of a battle - even despite the poor reputation that the galaxy-wide tyranny of Cold's family line has given the race as a whole, they have a tendency to be charming and charismatic by the standards of other races, with a reasonably high average intelligence to back this up and a very, very long natural lifespan allowing them to become very good at utilising both these traits to their advantage, and therefore make good sellers to the rest of the universe, this even reflecting in the Planet Trade Organisation's nature as, first and foremost, a company rather than a genocide machine. This further extends to their culture and society, which, whilst rather ascetic in nature due to the harsh conditions of their original homeworld, has a near-zero unemployment rate, and very low amounts of poverty, though as with any currency-based system, relatively few individuals tend to have more than the majority of the population at any given moment.

Interestingly enough, their original homeworld is one they have long since abandoned - their race was born orbiting a dying star that had been expanding for far too long for any one mortal to comprehend, leading to a need to adapt to an environment with little breathable atmosphere, extreme weather conditions, and comparatively greater rates of what we would call "tumors": the semi-keratinous and oddly-coloured biogems that many Arcosians possess are not naturally-occurring growths, despite their tendency to persist through generations in non-lethal forms, though the race as a whole has learned to accommodate for what were at first seen as horrific disfigurements in many of their members. In any case, if they had not acquired the technology to leave their home planet of Arcose when they did, a couple thousand years prior to the events of the Dragonball series, the race would almost certainly be extinct by now. As it is, they have for the most part survived, and integrated into the general galactic community, even finding a new, less hostile home planet for themselves and dubbing it New Arcose, though only a small proportion of the race actually resides upon the planet at any given time as of present. Incidentally, their evolution upon what would be considered a death world by most other races has led to them possessing quite frankly absurd levels of resilience - they suffer from long-term health conditions very rarely as an apparent response to cancer prevention, and whilst they may not be fully or even partially conscious in these cases, they can survive for fairly long periods of time after suffering injuries that would spell instant death for any other race up to and including severe brain damage, especially if they are trained in ki use, and can even "breath" in space for a certain period of time by absorbing the few particles that strike them into their bodies through their skin.

The true form of an Arcosian is something akin to that of Frieza or Cooler's fourth form - vaguely lizard-like, yet generally thin and unassuming even as their size increases with age, with box-shaped aural openings and bony white plates growing around their wrists, ankles, and occasionally their upper body and skull, whilst their visible skin is typically of a single solid colour akin to those present in human cultures, save where growing biogems have discoloured it, including an unfortunate tendency to grow directly beneath their eyes to the outward sides of apparently vestigial skin indentations that may have acted as tear ducts for their ancestors. However, at some point in their pre-history, their race evolved to possess the power of what is typically called Nightmare Transformation - the ability to grow and reshape a vaguely insectile biological "suit" around themselves, at first just for the sake of decoration and as a form of natural armour against both an enemy's attacks and their star's tumor-inflicting light, though later on with the capacity to surpress the sometimes overwhelming power their ancestors possessed to give them greater self-control, and in doing so to rapidly advance their civilisation's progress, though this capacity is rarely needed within most modern Arcosians beyond the deception of an opponent to hide their power, especially given the training their soldiers undergo; the form typically adopted as their "Diplomatic state" is officially in reference to that of the royal family in most cases, though any additional surpressive forms are based on the user's own preference. Interestingly enough, due to the biosuit's massive alterations to physical appearance, it is the case that an Arcosian within a biosuit is genetically speaking a completely different individual to their true form or even to other forms of the biosuit - whilst Arcosians can breed whilst wearing a biosuit (and, on an unrelated note, are in fact true hermaphrodites capable of producing children with themselves if so desired), the child may have completely different traits depending on the biosuit its parents were wearing, which has been useful in the past to increase the overall gene pool size. It has also been theorised that, with either near-perfect control over their true form's ki output or simply an overwhelmingly high power level, a well-trained Arcosian could adapt the power of Nightmare Transformation to, instead of growing a biosuit around themselves, modify their bodies directly to better channel ki, and thus to increase rather than surpress their power, though if there are any successful examples of this in the modern age, they have not been forthcoming in revealing themselves to Arcosian scientists.

With regard to Arcosian classification, members were originally divided by skin tone in the same manner as humans often are, with different naming schemes for different colours, though they typically possess extremely pale colourations evolved to reflect sunlight efficiently, with a very dark skin tone such as that of Cooler being the equivalent of an albino in human terms: prone to absorbing large amounts of radiation on Old Arcose, and therefore susceptible to a far higher risk of cancer or other health problems, though beyond the confines of their original planet this presents rather less of an issue. Beyond this general inclination toward heavy paleness, the tones that originally developed were somewhat based on the red, blue, and green colours of visible trichromatic light, plus a fourth colour registering as purplish to human eyes to account for a wavelength in the ultraviolet spectrum that Arcosians have evolved to perceive; "mixed race" Arcosians might have skin tones such as yellow, cyan, magenta, or even pure white in the case of extremely mixed ancestry such as that of Frieza's "clan", a.k.a. his family, though whilst wearing a biosuit it can be difficult to establish the Arcosian's true heritage, and doing so is irrelevant for breeding purposes anyway, as the skin tone of any given biosuit can be completely different to that of the Arcosian's true form even on a genetic level. The original royal family, a pair of blue-skinned Arcosians with names themed around ice, was genetically predisposed toward relatively high power compared to their fellows in the first place, and the entire family line has been very inclined toward further increasing this power regardless of other factors, resulting in sometimes-profligate inbreeding both with other family members and their own persons to try and achieve additional mutations toward greater power, and would-be heirs regularly being scorned in favour of their more powerful younger siblings, sometimes leading to backlash from those who lost out, the most infamous example of this being the space pirate Lord Chilled.

With the sudden loss of both King Cold and his two heirs within just a couple of years, many of Cold's retainers and even some of the stronger soldiers in the Arcosian army fought to claim control of the throne within the timeframe of Dragonball Z; it was ultimately acquired by a green-skinned lord named Pyre, who had the royal palace shipped to a planet orbiting a star turned unnaturally green by the experiments of a native race of another planet in the system, and dubbed himself the Green Sun King, retaining this title and position even whilst reports circulated about the supposed resurrection of Frieza himself. This state of affairs has lasted for quite a long period of time, to the point that Pyre has long since raised a child with another green-skinned Arcosian, naming the child Infer and dubbing him as his heir, the Green Sun Prince, but the rise of a group claiming planets previously purchased from the PTO is interfering with Pyre's rule over his people, in that said group is killing his people, intentionally or otherwise. Either way, he wants them stopped, and as it so happens, his son has yet to prove his true worth as a powerful ruler...
