"There's a throne challenger?" Ban muttered with a surprised expression.
The Enraged Crocodile as well as the Mild Tempered Crocodile came from the same tribe of crocodile Beasts called, Sentiment Crocodiles. They are the kind of crocodiles that live in groups, and depending on the 'emotion' they have, the stronger they are compared to others.
There were Happy Crocodiles, Lonely Crocodiles, Lustful Crocodiles and so on.
The Enraged Crocodile, which was the upper evolution of the Mild Tempered Crocodiles, was naturally stronger than the latter.
In one particular group of Sentiment Crocodiles, there should only be one Enraged Crocodile to rule them all.
However, that doesn't mean that there were no Mild Tempered Crocodiles who wanted to ascend to become an Enraged Crocodile. The problem was not on how to evolve, but whether they could evolve successfully.
