Astro and I were debating over which headcanon would win, so I made this. Also, if either of them dies they would have to be rushed to a hospital to heal. Aw, $#1+. Here we go again. I meet a bird plane thing in Glen Park after a tough gang war. Out of nowhere, he asks for a fight, and I haven't even maxed out my stats yet, but since I had taken control over half of Los Santos at this point, I didn't even care.
Remember that San Andreas takes place in 1992, the perfect time for Carl and Opa to have a fight. At the same time, gangs were rampant. So, apparently, even though Carl doesn't fully fit the description of "90's Gangster", Opa still wants to fight.
