Tyrell Wellick

Tyrell Wellick is one of the major antagonists of the USA drama series Mr. Robot, created and written by Sam Esmail.

He is portrayed by Swedish actor Martin Wallström, who made his American debut through the series.

Despite the fact that he works for the company whom the hacker group Fsociety is targeting, he does not appear to act against them and is only acts in his own interest.

Personality
Tyrell is intelligent and very perceptive, and he takes much pride in this, so much so that it can be interpreted as unbridled vanity.

He is also extremely intolerant towards failure, and is often prone to sudden fits of anger and/or violence, much like when he attacked a homeless man after learning that he would be passed over for a coveted promotion (which he slapped himself over as he flubbed his prepared statement).

He appears to be loyal to his company, E-Corp, but he will do whatever is necessary to climb the corporate ladder, even when it's against E-Corp's interests, much like when he deduces Elliot Alderson's role in the Allsafe hack that was framed on his superior, Terry Colby, but decides not to act against him to ensure that he can still attain his prior title of CTO.
