gamesradar.com:

The Guardians of the Galaxy 3 cameos are a sight to behold. The new movie, which is out in cinemas in the UK now, may act as a swan song for Marvel's favorite A-holes, but there are some other familiar faces lurking in the frames. So you'll want to keep your eyes peeled as the team unite for one final jaunt across the galaxy.

James Gunn's final MCU movie begins with Rocket's life in danger as Star-Lord, Mantis, Drax, Gamora, Nebula, and the rest of the gang will stop at nothing to save his life. Their dangerous mission will see them face some big new foes in the High Evolutionary and Adam Warlock in their most dangerous mission yet. However, while all of the usual suspects are there, there are also full of some other familiar faces. 

So if you're looking for all of the Guardians of the Galaxy 3 cameos you spotted, as well as some you might not have seen, then you're in the right place. Of course, it goes without saying that there are some big spoilers for the movie below - so make sure you've caught it at the cinema before reading on.

Nathan Fillion plays Master Karja in the third installment of the Guardians trilogy, one of the guards at the Orgoscope. The team encounter him when they break in to try and find the code to save Rocket and deactivate his kill switch. While they outwit him at first, Karja soon realizes something else is going on and targets them. 

This isn't the first time Fillion has appeared in the franchise either, after playing Kyln in Guardians of the Galaxy and appearing in a deleted scene in Guardians of the Galaxy Vol. 2. Fillion is probably best known for playing Mal in Firefly and Serenity and Richard Castle on Castle.

Fillion isn't the only cameo we spotted at the Orgoscope, either. Jennifer
