Unless he already has a name...
He's already known as "The Leader", but seriously, he's been named somewhere in the Cult of Arko thread a year ago, maybe longer. He's an actor of Turkish descent I believe.
I prefer for the name to be confusing to others, like naming your kid North West. So, let's name the Arko guy "Tabac". That way threads comparing Arko to Tabac will be way more entertaining.
That guys name is name is Marko...
the Arko guy.
