Mark Edward Fischbach, also known by his online alias Markiplier, is a Korean-American gaming commentator and actor. He is known for playthroughs of games, mostly in the survival, action, and indie genres, the most popular including indie, horror, and action games. Mark is currently in a relationship with graphic designer Amy Nelson and has a dog, a golden retriever named Chica.

Aside from gaming, Mark has also ventured into other genres, including acting and improv, often collaborating with Cyndago and other YouTubers and making sketch comedies and music videos with them. Recurring collaborators of Mark include the Game Grumps, Yamimash, and Jacksepticeye. Mark's signature icon is a pink handlebar mustache, personified by his character Wilford Warfstache.

Collaborations with MatPat

The first collaboration between Mark and MatPat was when Mark appeared in the Game Theory episode Why FNAF Will Never End. In the opening teaser of the episode, MatPat was trying to figure out a code to open the box at the end of FNAF 4, and successfully did so. The box opened to reveal Mark's signature warfstache, to MatPat's disbelief. Mark creepily said that "it was [him] the whole time, and that's no theory..."

MatPat briefly appeared in a vlog on Mark's channel titled ALL OUT WAR!!.

Mark's channel also appeared a couple of times in the Game Theory episode Is YouTube Killing Pewdiepie and H3H3...and Everyone?, specifically his videos I'M A MONSTER and BACK TO THE ISLAND!!

Mark and his friend Ethan briefly talked about MatPat and his Game Theory episode Toad's DEADLY Secret in his video SLOWEST RACE EVER | Mario Kart w/ Ethan - Part 2.
