Sneech's personality is described as a cunning, prideful, cocky, arrogant, and narcissistic, as he always brags about unusual (and expensive) stuff including toys, comics, etc, he often brags about his dad's position as a president director of a company and holds a deep respect towards him (he wants to be the successor of the company). His highest and most "easy-to-see" personality is narcissism, in which often he likes to look in the mirror and talk about how handsome he is (like the queen in Snow White). Some of the stories start with Sneech showing off some new video game or toy which evokes Noby's envy and irritation. He has extensive knowledge of science and is a talented artist and designer .He has the habit of inviting Gian and Sue to see something or go somewhere but always leaves Noby out with one excuse or another. When he did invite Noby to go somewhere, it was only to scare Noby or because Sue got so fed up that she refuses to go with him unless Noby gets invited.Whenever he is in so much pain or have been greatly humiliated, he usually cries for his mother.
