Throughout his whole life, the old toad suffered disdain from other predators, an experience that gave him huge trauma, which resulted in an inferiority complex and cowardly nature.
This suffering was because of his low-ranked bloodline.
This suffering also meant that sometimes, powerful predators felt it beneath them to specifically target and kill him amidst a group of prey. Well, it could be said that this suffering saved his life on numerous occasions but he felt indignant.
Why was it that other creatures with better bloodlines had deadly teeth for biting, a powerful tail for swimming, and access to powerful magic, while a toad like him only had his useless pair of jumping legs?
Why was it that those creatures were the predators while he was the prey? Why was he born a toad? How dare nature decides his species without asking for his consent first?
For years, since his days as a young mutated toad, he felt indignant at life.
