This is an interesting question as there are many things that I can say that would fit this question. Perhaps it is the escapism of being a magistical being from the prison of reality? A yearning to break free of mortality and depending on one's choice of mythos they base on, enforce morality or forsake them? Perhaps the desire for power and wisdom and something relatable as well, something many may seek in the sort time they have before they expire. Wealth, power, wisdom, dominance. All of these play factors into the fantasy and why many would spiritually associate with one instead of their innate humanity. Why be an ape lacking in fur that only thrives from it's cunning and intellect when there's so much more that could have been? This isn't something that is isolated either, every culture around the world has developed their own form of a draconic being be they protectors, destroyers, or just feral beasts that maurade across the kingdoms of yore. I mean sure, I can say being big enough to eat folks is my favorite aspect, but that is just an oversimplification of a much more philosophical and spiritual ideology that can be poised to ask why anyone wants to be anything else. At the end of the day however, our online persona's are for the most part an escapist fantasy, and even a reflection of one own's ideas and beliefs. Some just prefer strength, power, and wealth due to a lack of it in life, others may seek kinship, loyalty, and a sense of purpose as another.

To summarize this one up, it's much more easier to say that my favorite aspect of being one is not only the sheer flexibility, but also the iconography that predates the fandom itself. Even back in medieval and ancient times nations flew dragons in banners and coats of arms across the globe, a sign of power, regalty, and even dominance but also a sign of wisdom and prosoperity. All these elements coming together to form a being of perfection, of everything we all strive for even though many can only hope to achieve in life, yet never is it impossible to reach and always remains as a life path to follow.

I would undoubtedly be highly difficult, if not borderline broken given the fact my character is designed more so along magical prowess instead of physical prowess. This ultimately means he's quite powerful in spellcasting and would pose a significantly unfair challenge to those with little to no magical defense, however those who only spec into magic defense aren't safe either. He is a dragon after all and has serrated claws and a bladed tail for a reason. Expect something along the lines of a dark souls boss that would require lots and lots of timing between attacks, some of which may be telegraphed just enough to give you barely enough time to get out of the area of effect and realize that they're just toying with you and going easy, because this dragon has razed entire towns before! As for his magic, in the universe Vul is from, there is no such thing as 'mana', but instead using your own stamina to cast, and when that's our it becomes akin to blood magic where it drains your very life force... Unless you have souls to sacrifice for spellcasting instead, which unfortunately for any would be player, Vul has devoured and absorbed countless billions so expect lots and lots of spells. All the spells. Yes, even fireballs and lightning.

Imma be real with you I have no direct answer for this question. I can't exactly pinpoint why it's so satisfying to have someone slide on down one's throat, knowing well what fate awaits them inside. Perhaps it was the voracious plants in Wind waker and Twilight Princess that got me, or some of the cartoons. Or maybe I just have a morbid fascination with the serpent like creatures capable of swallowing things whole (which is why snakes are pretty fucking cool don't lie) and there are just many other factors to about it. The bonding experience one shares, the sense of dominance over the other or the absolute feeling of empowerment that one can only live out in fantasies. Either way, regardless of how you look at it there's no easy answer.

What is there not too like? Why, they are nigh perfect organisms just as they are apex predators. Sure, there is the appeal to power, but you'd be lying if you said you wouldn't fall in love with a scaly hunk. Than there's the complexity in both designs, personalities, and overall characteristics due to the fact that they're a global phenomenal spanning multiple cultures from eastern to west. In short, the amount of ways you can present one and design one can be just about what you want. The regality and projection alone is enough to justify them, but you can do so much more with such a largely well known yet often varied being that you can't get with well established species.
