Azdaja is a skilled professional killer that handles most of the planning and scheming side of things, as mentioned by Konyyl in volume seven. He uses his device--a scouter--to scan for information, be it for coordinates or in the player's case, their species. He also stresses the importance of having good strategy so that he and the player would have a tactical advantage in Duel Strifers; urging the player to increase their pace so that they can surprise their opponents. Thus, it can be inferred that he understands that having all relevant information on a particular person or subject would place him in a better position to execute plans. Despite this, however, he winds up mistaking the player for someone else entirely even though his other deductions were correct.

He is noted to be a bit pompous in terms of personality; the player notes that he appears to enjoy listening to the sound of his voice when explaining the intricacies of Duel Strifers, hence his excessively detailed spiel regarding the subject. Azdaja also uses his psionics to flap his overcoat just for the sake of creating a dramatic effect, regardless whether there is a breeze. When attacked by a cerulean girl, he becomes visibly angry as he cannot believe someone had the gall to mess with him. Also, he is quite smug about his exceptionally strong psionics; scoffing at 'weaklings' that desperately want an unbeatable psionic on their side. It should also be noted that he does not like mediocrity, given the fact that he believes being gifted entitles him to a better life.

Even though he may be self-centered at times, he still knows when to thank the player for helping him out in the game. This is evidenced by the roundabout way he expresses his gratitude towards the player, and he insists that celebration is in order once he and the player collect the cash prize. Azdaja is more than willing to split the winnings with the player, showing that he isn't all that egocentric.

As mentioned earlier, Azdaja is an incredibly powerful psionic, the strongest one the player has met so far. When Azdaja picks the player up with his psionics, the player describes the sensation like 'stepping on a strong breeze'; when Kuprum used his psionics to levitate them, it felt like being yanked up by the scruff of the shirt. Another example is shown when Azdaja is briefly mind-controlled by the cerulean girl, his eyes glow so brightly the sight scares the player witless. As it were, he possesses exceptionally strong psychic powers that makes him the envy of others, and is frequently approached by others that want a powerful individual on their side.

While the final bullet point on his Troll Call card describes him as a good listener, Azdaja seems to only extend this courtesy to people he's well acquainted with. This is best illustrated in one of the bad endings: during his heated debate with Konyyl regarding the player's true identity, he quickly accepts her description of the player without much fuss. When the player attempts to explain themselves in either of the bad endings, however, Azdaja pointedly ignores the player's frantic words and either drops them or begins attacking the player. 

Despite being a lowblood, he and Konyyl do not care for the plight of the oppressed. He outright states that he has very little regard for both the Empire and the rebels; as long as he and Konyyl have killing to do and money to earn, he couldn't be bothered by political events on Alternia. However, Azdaja does not seem to relish the idea of being sent out to space by the Empire, as it means that he can no longer do cool things of his own volition. 

I'd imagine him sounding like Vegeta or Sonic the Hedgehog.
