Johnny wouldn't work with the Online player cause
1. The Online character canonically works for Trevor
2. He/She has stolen drugs and bikes from the Lost
3. The character's killed a LOT of Lost, be it from Gang attacks, Gerald/Trevor/Ron missions, and in Heists for Trevor and Lester
thats a very good argument, so working for him would not really make any sense. Perhaps do some Trevor missions in which he appears in the cutscenes? A mission in which you must sell meth to Johnny or something? Also the guy that said something about preventing Ashley from being gang rapped would make a lot of sense.
Because in GTA V The Lost, The Ballas, The Vagos, etc are the "bad guys" so youre never gonna do something to benefit them or work for them.
But then....we also have Terry and Clay and from what we see in the Mr. Phillips mssion both of them are very known characters in the Blaine County Crime/Meth Deal scene. Perhaps some missions/heist featuring them? As enemies or something like that?
I always wondered why he didn't appear online, he'd be a cool character, even if it was one cutscene during a heist or mission, so I decided to solve the problem myself
Hahahahaha he looks like Johnny K after 10 years of meth. But I think that due to the poor customization options that GTA gives you thats the most accurate your character can be to Klebitz. I mean in GTA:O all characters have the same height and body....not fat or skinnys...everybody have the same f*cking body. (Except females) But maybe thats because of what a problem will be for all the clothes and stuff.
