Elgrim the demon-lord

Elgrim the demon-lord was first mentioned in the DougDoug episode, "I forced an Ai to play a kids adventure game."

Elgrim is summoned by sacrificing 18 children. While it is not shown, it can be deduced that Elgrim is summoned at 1:32:14 due to Sam 18 being killed. It is unknown whether Elgrim will appear in any future DougDoug Cinematic Universe projects.

Despite the fact that Elgrim likely resurrected at the death of Sam 18, DougDoug still kept sacrificing Sams. DougDoug is likely too stupid to realize that Elgrim doesn't necessarily have to resurrect where the sacrifices took place.

He was first mentioned by Sam 4 before later having a full explanation given by KamesaurOG.
