Part 4 to my Markititan series! I'm really enjoying doing crossover fanart its so much fun! :3 So I remembered how Eren from Attack on Titan had this crazed serial killer look on him when he wanted to murder the female Titan when he was penetrated by debris (don't ask me which episode it was I can't name it at the top of my head) And then I wanted to do some Darkiplier fanart as well. You all remember how crazy Mark gets towards the end of his happy wheels videos and murders all the people?? So this to me was a perfect crossover. I'm grateful to you guys for liking my art too! Hope you like this one as well! I do not own the concept of Attack on Titan nor Markiplier.
