One characteristic is the intense power struggle. Alphas are usually strong - willed, so in these novels, there's often a battle of egos at first. For example, they might compete for dominance in a certain field.
I'm not sure specifically what 'Alpha Mate Novel' is about as there could be many novels with that name. It might be a story about a special relationship, perhaps in a fictional world where the concept of an 'alpha' is important, like in some werewolf or fantasy settings.
Another good alpha x alpha BL novel is 'Love by Chance'. It shows the complex relationship between two alpha - type characters. The way they interact and gradually fall in love is really interesting.
There could be various interpretations of the 'alpha's hybrid mate' story. It might involve a character who is an alpha (perhaps in a werewolf or some hierarchical group context) and has a mate who is a hybrid (a combination of two different species or types). However, without more information, it's hard to tell the full story.
One common theme is the power dynamics between the alpha and omega. The alpha is often seen as the stronger, more dominant figure, while the omega is more submissive. But in many fics, this dynamic is explored and sometimes subverted.
Typically, in 'alpha predator bl novel', one of the main characters often has dominant and strong - willed traits, like an alpha. There's usually a power dynamic at play in the relationship between the protagonists.
Often, the Alpha himself is a very popular character. He is usually depicted as strong, powerful, and having a sense of responsibility towards his pack. His character arc might involve learning to balance his duties with his love for his mate.
As there's no definite information about 'Alpha Mate Novel', it's possible that the main characters are from different backgrounds or species in a fictional context. For example, one could be a powerful alpha from a noble family and the other a commoner who turns out to be their fated mate. There could also be antagonists who try to break their bond or use it for their own gain.
I'm not sure exactly as I haven't read it. But from the title, it seems that there might be a love triangle - like situation where the king's wife has some sort of connection or is the mate of an alpha, which would likely lead to a lot of conflict, both political and personal.
The main characters are likely to be the alpha and the thrice - rejected mate. The alpha might be a complex character, with responsibilities towards his pack. The mate could be an underdog type of character, who has been through a lot of pain due to the rejections. There may also be a mentor - like figure, perhaps an older member of the pack who gives advice to the alpha or the mate. All these characters would interact to create the story's plot, with their actions and decisions shaping the outcome of the relationship between the alpha and his thrice - rejected mate.
