Starfire. LeBron James? guest starring as himself on the show. The basketball star appears on the episode "The Cruel Giggling Ghoul" on Thursday, February 11, 2016 at 6pm. That's timed with the NBA All-Star break, something Turner networks (of which Cartoon Network is one) will be covering heavily. Here's hoping we can see him don this costume live sometime. He also plays basketball pretty well, I guess.
