Markiplier

ah yes... markiplier, he first appeared in Ze rp during one of meggy's dreams. Classic summoned him to help fight bernie but he started jumpscaring everyone and jump punching them. Due to this markiplier goes pretty far back in Ze rp, however in the past he was always more of a side character that was used for one off gags. 
Later on he saw some action during the gacha troops invasion, in which the gacha troops had grown in power due to being likely trained by the hunter who had gone dark at the time. After that point he was still more of a side character appearing randomly to either punch a villain out or seduce one of the heroes with his toned body. 
He also fought matpat in the battle arena when jean was still tryna seduce koby. Soon after he joined mr beasts squid game, he played dirty and tried to punch people, mainly keqing. After barely surviving the minecart trial where koby used the force to throw many rocks at the contestants, he later lost when he got jumped by thugs in the maze trial.
As time passed koby would often summon mark to help fight villains and they ended up becoming good friends. Not too long after the hunters invasion with many powerful armies, the armies attacked the town of scam. Mark fought as best he could but despite throwing a chair at them and shooting them with guns mark was overwhelmed, His last words were, "PLEASE SOMEONE HELP!"
fun fact: mark, right before the hunters invasion became more of a "main" character who talked to people and appeared more often, usually with his other youtuber buddies, mr beast, matpat, and sometimes jacksepticeye.
