Kraw is a very smart Mixel with a rather large ego who is very overconfident. At least that's what he believes as he often has many moments of stupidity, often denying and forgetting that he had them, and is also irresponsible as he often do idiotic things that lead to dangerous results. He is also a bit over-dramatic and has a tendency to yell and panic easily, making exaggerated facial expressions while he does so, which sometimes startles other Mixels that happen to be near him at the time.
