Now we have Wildmutt. One of Ben 10 character, Wildmutt is the omnitrix  alien whose physical features are a combination of a lion and a gorilla. Wildmutt has such powerful arms that make him able to run, jump, and climb objects at high speeds.  Although he  doesn’t have any eyes, but but has gills on his neck. Those gills allow him to hear and smell many times better than humans, giving him radar-like sight. In short words, this dog-like alien is vicious and fast!! So, what are his weaknesses? It is obvious that one of his weaknesses is his lack of sight. Then, his nostrils (only if they are clogged). The other weakness is that he cannot speak in any understandable fashion. What he can do is just snarling and growling and that can be a problem when attempting to relay messages.
