Although quite cautious and timid, Blendin was sent back from the year 207̃012 (pronounced twenty-sñeventy-twelve) to remove a series of time anomolies. When Dipper and Mabel approach him, he explains that he is a time traveller doing his job, only for the time police to come and arrest him later. When they do, his mood and personality suddenly change to angry and malevolent, swearing revenge on the Pine twins and saying that he'll make sure their parents never met.
