Lixian

Luís Costa, better known by his online alias Lixian, is a Portuguese online entertainer, animator, video game developer, and Markiplier's editor since early 2018. Lixian has made numerous fan animations that have been featured on Mark's channel and is also credited with designing Tiny Box Tim's appearance.

LixianTV
Lixian's first channel was made on December 1, 2012, where he specializes in creating animations for prominent YouTubers, some of them being Game Grumps and Markiplier, as well as from his own gaming content featured on his second channel, LixianVG. In 2013, Lixian started a series called Making of, in which he would show his process of animating a video. In 2016, he started Just my opinion series that would cover his takes on various topics of personal interest. In early 2017, Lixian became interested in video game design and would later create several indie titles using GameMaker studio. In 2020, Lixian did a charity livestream for COVID-19 relief.

LixianVG
Lixian made a gaming channel on May 5, 2012. From 2013 to 2017, he posted a variety of gaming videos, usually accompanied by his friends, some of the most prominent revolving around Dark Souls and Grand Theft Auto V. On July 1, 2017, Lixian uploaded a video titled "The End Of The Channel" in which he explained that he was no longer interested in keeping the channel active, as it became too stressful to manage two accounts at once. Almost two years later, Lixian once again started uploading short clips and compilations of his gaming livestreams to his second channel.

Working for Markiplier
In late April of 2013, five days after making "Wilford Warfstache" animated short of Markiplier's Amnesia: Rain Let's Play, Mark offered Lixian a job via email as an animator for his markiplierGAME channel, which Lixian happily accepted. While working for Mark, Lixian would continue making separate animations for his own channel, which helped him improve the quality of his work. Lixian's design of Tiny Box Tim would become the character's default appearance.

In late December of 2017, after taking notice of his video editing work on the LixianVG channel, Mark hired Lixian as a temporary editor for his markiplierGAME channel. As he had doubts about the quality of his early editing work, Lixian asked Mark not to credit him as his video editor. In early 2019, Mark promoted Lixian to a full-time video editor and raised his salary. His first editing job was on the video "THIS GAME WILL TORMENT YOU" in early 2018, and his first official editing credit was "THE 'OL TYRANT SWITCHEROO." Between 2019 and 2020, Lixian, alongside Marcus, Rachel, and Diceroll, worked as an additional editor for the now-defunct Unus Annus channel. Of the 367 publicly available videos, Lixian worked on a total of 33.

While editing Mark's content, Lixian would use his animated character to leave editor's notes inside various videos, which ended up becoming a running gag on Mark's channel. Following Lixian's short hiatus in late 2020, Mark created a stick figure caricature of Lixian named Lunky as a sarcastic substitute for his editor. The character would later become a running gag on the channel, often getting into conflicts with Lixian's animated persona.

For Mark's thirtieth birthday, Lixian developed a loose game adaptation of "DAMIEN"—one of Mark's animated short stories—as a belated birthday gift. In 2021, for his thirty-second birthday, Lixian developed Warfstache Clicker.

In In Space with Markiplier, Lixian is credited as one of the film's consultants.

On June 21, 2021, Lixian announced on Twitter that he was expecting a child. His child was born on August 22, 2021.
