Stakar and Co.

Sylvester Stallone’s role in Guardians of the Galaxy: Vol. 2 was revealed a couple of weeks before the movie’s release. Fans were excited to learn that his character was Starhawk, a comic book superhero and one of the original Guardians of the Galaxy. But when the movie arrived, his reveal was a bit underwhelming. In a cameo, Stakar butted heads with Yondu, providing the latter with a bit of backstory and expanding on the mythology of the Ravagers in the MCU.
It all turned around when additional original Guardians were revealed as Ravager leaders.
Of course, this could have ended with just a simple cameo. However, James Gunn said that it was actually quite a major reveal, since Stallone’s character’s role (and presumably his buddies’) will expand in future MCU movies. And, while we can expect these characters to appear in Guardians of the Galaxy 3, we believe that other cosmic installments might welcome them before that (Thor: Ragnarok, Captain Marvel, Infinity War).
