Tyson frequently acts like something he isn’t to make people underestimate him, despite refusing to admit that he’s an underdog, and prefers to be seen briefly rather than completely invisible; leaving a false impression, rather than none.
It is incredibly rare that Tyson will pretend to have an ability or be something that he isn’t, that implies more knowledge than he has. Tyson is completely comfortable convincing people that he isn’t as smart as he actually is or that he isn’t as physically capable as he actually is.
However, Tyson hates the risk of giving the impression that he’s more talented. That impression can bite him in the arse much easier, especially if the wrong person is given that impression and needs to rely on him to provide something that Tyson isn’t capable of giving.
