Well, I have these species called Salaziers, they are giant geckos and their original color describes their personality.
The blue ones are the most aggressive, and want to eat anything they see, but they usually get killed by X-eis.
The red ones are the most kindest, they only eat plants and is willing to help anyone.
The green ones are most laziest, but once you anger them, they become aggressive.
The orange ones are the fastest of them all, but become more tired than others.
