Mertin Fargleman, also known by his supervillain named Professor Twiny Vines, is a character in Back at the Barnyard and the main antagonist of Cowman: The Uddered Avenger. He is Cowman's arch-nemesis.
His parents did not love him as a child. This is most evident by his name "Mertin". He was thrown into a dumpster as a chid, left for dead, until Jourdan Harold found him and returned him to his parents. His parents again threw him out onto the street at the age of 13, where he had to rely on plants to survive. This is why he became a plant villian
Mertin is a twisted botanical genius, as well as being a genius in plants. He created many mutant plant hybrids, such as deadly constrictor vines and exploding avocado bushes. Year after year, they were rejected at the county fair. He wanted to steal the Jurassic Corn Kernel to create a plant so amazing, so terrifying, and capable of bone-crushing mayhem, which was a giant corn monster so he could let go of his anger to the people and to win the blue ribbon. After he is defeated then arrested, he vows to write angry letters to Cowman while planning his revenge.
