As shown in the films, dragons like "bewilderbeast" and "Seadragonus Giganticus Maximus" are alpha dragons by nature.
But it also showed the transformation of a night fury into alpha, so for this and the capacity for transformation that can be made in the game for mobile, I pose several questions...
Can any dragon become alpha? If so, what are the requirements that are needed to adquire this transformation?
Can there be certain alphas "by species"? For example an alpha between the "nocturnal fury's" and a "bewilderbeast" above this.
