Are there any official cross game character appearances in rockstar games?

The only verified information supplied is from the Wikipedia entry for the Grand Theft Auto series, which describes the franchise’s gameplay, development team, and general scope. This entry does not mention any instances where a character from one Rockstar title appears in another Rockstar title. Because the source does not provide evidence of cross‑game character appearances, we cannot confirm that any exist. Therefore, based on the verified data, there are no known official cross‑character appearances in Rockstar games.
