Snake Girl Rayla?
The TDP fandom has always had headcanons that didn't really work out (such as Soren rather than Claudia staying loyal to his father), but the idea of Callum being some sort of "Snake Boi" seems to have stuck around despite having basically no support in canon.
This isn't to discourage people who like the aesthetic. People who think it would be cool if Callum was That Way. By all means, keep writing those stories, making those fanarts! Many of them are downright inspired, and represents a really interesting direction the story could have taken.
But "could have taken" is the operative term here. The traits that are associated with "Snake Boi" Callum (listed below) barely represent what his defining traits really are:
Obsession
Ambition
Temper
Ruthlessness
Selective Loyalty
There are, of course, shades of the above that ring true with Callum, as they ring true for most of the main cast. But it seems odd to single out Callum as the one who most exhibits these traits. Other characters who better exhibit, say, selective loyalty (such as Sarai taking a stance against hunting the Titan but ultimately sides with Harrow), are never recognized as such, let alone singled out to the extent Callum is.
Or they're based on interpretations that are dubious at best (Callum "turning against" Viren, a man he's never shown a particular liking to), or false at worst (Callum being the only one to actually want to kill Aaravos, despite the fact that killing him was originally Rayla's idea). So given all this, it's curious as to why "Snake Boi" Callum as an actual theory of who Callum is stuck around for as long as it did.
Then it hit me: much of this is really a projection, because there is a character who does exhibit these traits far better than Callum - Rayla.
Obsession
Rayla's obsession brings out the best and worst in her. She would obsess over what the right thing to do is ("I hesitate, think too much, get confused about the right thing to do"), but then also become obsessed over specific goals, first over killing Viren, then over the coins.
Ambition
All of the main character display some forms of ambition from time to time, but Rayla seems to have dispalyed hers at a much younger age:
At an age when most of the other main characters were just having fun and getting to be children, Rayla already chose her path. She wanted to be trained day and night by her mentor, despite her parents wishing that she have fun and grow up. To set aside a normal childhood and deciding on a career at that age, that takes ambition.
Temper
It should go without saying that it doesn't take much to set Rayla off:
So whether it's being mistrusted, being lied to, being rejected, being called weak, or just plain hungry, Rayla has a history of getting pretty angry.
Ruthlessness
I mean, c'mon, look at that smirk...
Or that death glare...
If that's not enough, here is what Rayla was planning to do with Claudia and Soren at the Cursed Caldera according to the novelization:
Selective Loyalty
Last but not least - selective loyalty. I think this is best exhibited by Rayla being willing to scuttle a two-year mission to kill Viren by saving her family instead:
But also by her insistence that "we can't save anyone," typically hinting at the belief they have to look out for themselves and their in-group before others:
But this is also hinted at throughout the series. She goes to save Pyrrah from Soren and Claudia, but doesn't express similar empathy for the humans in the nearby town that the dragon burnt down. Evidently, the bonds of loyalty are a strong influence on her actions.
So much so that in ToX this is Rayla's defining trait:
So on the one hand it's curious that Rayla's "most important value" is often assigned to Callum in some headcanons, but on the other I do get it. People want Callum to be selectively loyal, because that would mean he is selecting Rayla. That he's more loyal to her than he is to any pesky moral principles, that she's his ultimate value. What's more romantic than that?
But this does have the uncomfortable nature of being wrong: the truth is Rayla is the more selectively loyal one. She ultimately chose Callum over her quest to find Viren - doesn't get more loyal than that.
Conclusion
I don't write this to disparage anyone's theories or beliefs, but merely to point out what I think should be clear by this point: every single trait Callum is thought of having - temper, obsession, ambition, and especially ruthlessness - better describe Rayla. I'm sure people don't mean to project Rayla's traits onto Callum. It does seem to be done so in order to let Rayla be an uncomplicated hero with no moral issues, but in doing so I think people unintentionally ignore Rayla's best side.
Her obsession lets her stay on task. Her ambition shaped her into a great warrior. Her temper means no one can run roughshod on her. Her ruthlessness means she has what it takes to get the job done. And her selective loyalty means that when she says...
...she means it.
