Yarrow

The Yarrow was the head of the League of Mary Sue Factories. He was a very bad-tempered Flower and intolerant of failure, as shown when he had the Pipe-weed infected with the tobacco mosaic virus for taking too long in its preparations. Prior to the death of the Mysterious Somebody, he was the Administrator of the FGenMS08 Mary Sue Factory. During the Crashing Down crisis, he received a shipment of samples which were used in the creation of later generations of Mary-Sues.

He was killed by Agent Harlan during the 2008 Mary Sue Invasion in revenge for Makes-Things' death, before he himself was killed by the Yarrow's bodyguard. His death was followed by a power struggle between the Forget-Me-Not and Venomous Tentacula, which ended in October 2008 with the Tentacula's victory.
