Which entity is this text about?

Charles Bartholomew "Chuck" Bass is a fictional character in the novel and television series Gossip Girl. In the TV series, he is portrayed by English actor Ed Westwick. Although he is a secondary antagonist in the original book series, the TV series elevates him to an anti-heroic main character, where he is noted for his financial ambition, hedonism and personal style.

When Season 3 returns, Chuck and Blair are very happy and very much in love. Chuck struggles to run Bass Industries to his deceased father's impeccably high standards. He buys The Empire Hotel. Halfway through the season, Chuck meets a woman claiming to be his mother called Elizabeth Fisher. After initially rejecting her, Chuck finally accepts Elizabeth and is then met with a sexual harassment claim from his former employees. Despite his innocence, he settles to keep the scandal out of the media. Jack Bass, Chuck's sinister uncle, informs the media anyway and necessitates Chuck signing the hotel over to Elizabeth to appease the public. She betrays him and signs the hotel over to Jack, whom she loves. However, she calls Chuck to say goodbye and reveals that Jack chose the hotel over her. She then reveals to Chuck that she is not his mother and she does not know whether his real mother is alive or dead.  Chuck and Blair agree to team up to take down Jack to get the hotel back. Jack tells them both (separately) that he will only give up the hotel if he has sex with Blair. Unbeknown to Blair, Chuck sets the situation up and Blair goes to Jack's. After a kiss, Jack tells Blair the truth about Chuck's involvement. Blair breaks up with Chuck and he gets the hotel back, vowing to get Blair back too. Chuck tries desperately to win Blair back, doing everything from banning all of the other Upper East Side men from dating her to asking her to meet him on top of the Empire State Building. Blair decides that Chuck is her true love and she's going to meet him, but Dorota suddenly goes into labor and she ends up being two hours late. Chuck, thinking she is finally over him, leaves the building heartbroken and nearly suicidal. When he gets home, he sees that Jenny Humphrey has arrived looking for Nate. The two drunkenly sleep together, heartbroken that their true loves don't return their feelings.  Blair appears later in Chuck's suite, apologizing for being late, and the two reunite (sleep together). Chuck is about to propose to Blair at the hospital, as they visit Dorota and her new baby, when Dan appears and rashly delivers a punch to Chuck's face. He then forces Chuck to tell Blair what happened between him and Jenny. Blair breaks things off with Chuck and informs him that it's over for good. She also threatens to ruin Jenny's life if she doesn't leave Manhattan immediately. Chuck then travels to Prague to escape New York for a while, feeling as though he has nothing left. He gets robbed by two muggers who insist on taking the ring that Chuck intended on proposing to Blair with and when Chuck puts up a fight, he gets shot. The last shot of season 3 is him lying in an alley, presumably dying.
