Marco Volker has made me laugh out loud more than any other character in V7, and there have been some really funny beats this version so that is saying something. He's quirky, unpredictable, and yet at the same time has the edge to him, this hint that stuff could suddenly get really serious with just one or two things going wrong. He's established a great dynamic with Arjen Kramer, as both characters frustrate and torment each other in different ways while still feeling like there's a level of, if probably not actual affection quite yet, at least familiarity and comfort in dealing with a known quantity.
A lot of what makes Marco work so well is his voice, both in speech and in narrative. It has a sort of manic emphasis to it, a charisma that just dares you to question what he's saying. I'm going to pull out a couple of my favorite posts that illustrate this: one when he opens fire on the boat which manages to take something I usually can't stand (CAPSLOCKED. WORDS. SPLIT. FOR. EMPHASIS.) and make it one of the most amazingly funny chunks of writing in the version to date, and another when he mentally flips out over being baited into giving Arjen an opening to complain further, because it's just such a relatable moment of exasperation and yet it leads into a pep talk that is, if imperfect from a results standpoint, at least well-intentioned and also a hoot to read.
