The actor who played Trevor in GTA V wants the character to appear in the new part of the series for a spectacular and atypical conclusion to his story

Stephen Ogg, known for his role as Trevor Phillips in Grand Theft Auto V, has expressed a desire to return to his iconic role in GTA 6, but with an unusual proposal: he wants his character to be killed at the beginning of the game.
Here's What We Know
In an interview with Screen Rant, Ogg said that it would be fun if Trevor appeared in GTA 6 only to be killed at the very beginning. He believes that it would be a kind of gesture of gratitude to the fans and a symbolic passing of the baton to a new generation of characters.
This idea is reminiscent of the scene from GTA V where Trevor brutally kills Johnny Klebitz, the protagonist of The Lost and Damned expansion pack for GTA IV. Thus, such a storyline could become a bridge between the two parts of the franchise, paying tribute to old fans and opening the way for new characters.
There is currently no official information about the return of Trevor or other characters from GTA V in the next instalment of the series. Rockstar Games is known for its secrecy, so details about GTA 6 are kept under wraps.
GTA 6 is scheduled for release in 2025 for PlayStation 5 and Xbox Series X/S. Information about the PC version will be announced later.
