Cranky grew up in the Plains of the Valbarra Archipelago.
Every day was a struggle to survive.
He wasn't born fearless.
On the contrary, he was a very cautious, opportunistic monster, putting even Camazotz to shame.
But as the years passed, he realized that only the strong could survive in this world. So, with that in mind, he decided to become strong.
He had lost many times, but fortunately, the monsters he had chosen to fight were Herbivores.
Meaning, even if he lost to them, they wouldn't eat him, allowing him to live another day.
With every defeat, Cranky learned how to fight, and as the years went by, his rank steadily rose.
His first battle against an Apex Predator in the Plains ended in a draw. Both of them were targeting a bison, and it just so happened that they charged at it at the same time.
His first opponent had been a Wind Wolf, who was not only fast but also very cunning.
