Darko

Darko is a evil-like being who looks similar to YouTuber Markiplier's evil persona, Darkiplier.

Darko was also a demon/evil version of Darko.

Description
Darko is the evil version of Dawko appearing in more recent videos. When Ultimate Custom Night was in development, Dawko made a challenge with Scott Cawthon where he can get to interview Scott Cawthon if he beats 50/20 mode, while he has to make a fan game called FNAF 7 if he gives up. Dawko mentioned if Scott made the game harder, his sanity will drop. When the sanity finally dropped to 0%, Dawko posted a video called "a message to Scott Cawthon :)". In the video, Dawko had become insane and kidnapped all his friends, 8-BitRyan, Bazamalam, Razzbowski, and DAGames. He threatened Scott to make the game easier, but the friends successfully escaped except Bazamalam. This video marked Darko's first appearance.

Darko made another cameo appearance in a video named "51/20 Mode?...". He acted as he didn't remember what he did to his friends, and while he read Scott mentioning "51/20 Mode", Darko took over his body for a minute.

Unlike other YouTuber's alter egos, Dawko didn't fully act like he didn't know anything about Darko. He claimed that the video was just a joke and nothing really happened (although Darko's eyes appeared at that time). In the next video, he even directly said that Darko had taken a break for his holiday, since then Darko has not appeared in a video, presumably indicating that video marked Darko's last appearance in Dawko's channel.
