Given the liberties that James Gunn has taken with the source material before, we won’t be surprised if the characters wind up being radically different, but we’ll have to wait until we see more of Stakar Ogord on the big screen to determine just how close it winds up being.
In the comics he has powers that he shares with Aleta that come about as a result of them reanimating a dormant deity called the Hawk God, and it’s unclear if that backstory will be included in the live-action adaptation.
As you can see in the image above, the Marvel Cinematic Universe’s version of Starhawk doesn’t quite match up with his comic book counterpart aesthetically beyond the level of allusion — and it is yet to be determined how far other comparisons will go.
