My Gungrave headcanon is that Brandon Heat/Beyond the Grave is Mexican due to the fact that he is directly inspired by El Mariachi from the movie Desperado
As much as we praise Robert Rodriguez for From Dusk Till Dawn, Sin City, Planet Terror, Alita: Battle Angel and even bullshit like Spy Kids and Machete or whatever, Desperado from 1995 is still in my opinion his masterpiece.
One of the greatest action movies not just of the 90s but ever made in general.
An incredibly effective, incredibly well made small scale action movie that shows that creativity is used to solve problems instead of money if you put your mind to it.
