Here is finally my own fursona ,thanks to the base that  Caindra made below is a little text about his personality maybe later I goign to update with some more things or give it a little more of organization.

he is male gator with a well fitted body, but he is really timid one and when he try to talk with someone for the first he always get cold feet and he make a deep and low grunting that to everyone sound like his roaring a bit, that normally scares all the one who try to get close to him , but is you have the valor to talk with him even after his growling you are going to get to know a very friendly cocrodile, who really likes everything about giants robot even you can see that everytime that talk about mechs he become really childlish about that is eyes start to spark and his tail start to wagging like a dog.
