Eagle-eyed viewers spotted a possible Beta Ray Bill easter egg during Avengers: Endgame.
On Marvel Studios' Reddit, fans found the easter egg during the film's midpoint, where Nebula and Gamora are on the Korbin. The script reveals that the two are on the "Korbinite home world," which is the home planet of Beta Ray Bill.
Korbin was the home planet for Beta Ray Bill and his fellow Korbinites before being destroyed by Surtur's Fire Demons. Deemed as the Champion of Korbin, Bill made its debut in 1983 in Thor #337. He has made a few appearances in animated Marvel television series, and had a reported cameo in Thor: Ragnarok scrapped in the early stages.
