What dastardly fate has befallen Azar now? This must be the fault of some mischievous wizard-type who cursed the poor dragon to ensure that a giant fire-breathing reptile couldn't stop their evil plans! Or maybe someone spike his food with something and now it's rendered him completely immobile! Certainly it couldn't be that Azar fell to his own gluttonous vices and stuffed his face with so many decadent foods, not taking account for how much heavier it was making him in the process. Regardless of the cause, the end result was the same. Azar's used to carrying heavy weights while flying, as he's used to transporting supplies for his inventions and people from place to place. But even he can't lift a belly that big and a body that heavy no matter how hard or fast he flaps those wings.
Either way, it looks like he's trying his hardest to either trying to catch up with the one who did this to him so it can be un-done, or (more likely) escape to a good hiding place before anyone sees him like this! After all, it wouldn't do for people to see the sleek and slim dragon inventor as a big blubberball!
