Evel Knievel is an iron golem that was created by CaptainSparklez on Episode 28 of his survival series.
His name comes from the fact that he started attacking the mobs in the mob trap. Later in the series, Knievel was found stuck on a fence. Eventually, he stopped appearing or being mentioned, and it's assumed that he fell down into the farm.
He was named after "Evel" Knievel, a famous daredevil and stuntman.
