Simon West and Mark West are the male counterparts of Susan Test and Mary Test. Simon West was voiced by Ian James Corlett and Mark West was voiced by James Arnold Taylor. They made their first appearances on the episode Johnny Alternative when Johnny Test and Dukey were sucked into a portal that sent to them into Simon and Mark's world. Simon and Mark's parents might look exactly the same as Susan and Mary's parents, because there is a picture in their house that looks exactly like Lila Test, although it could actually be an oversight when that background was being recycled for that setting.
Appearance[]
Simon looks almost exactly like Susan Test but with short hair. His brother Mark also looks nearly exactly the same as Mary Test with short hair.
