Jiruses are the most iconic version of Dimension travelers ever known. Jiruses were usually once former humans but when they started taking dimension traveling for granted, they had been deformed. Just green slime with stick-out eyes. Although, the King of all Jiruses had created a way to help them. He gave all of the deformed Jiruses a clear head dome and small, round armor to hold the green slime in place. The king's name was Mastro.
