Calvert

He is the father of Pickles and Seth and is married to Molly. His occupation is unknown, although he generally maintains a clean-cut businessman look. He speaks in a low, raspy voice and does not seem to share the heavy North Midwestern accent of his wife and sons. Like his wife, he constantly dotes on Seth while expressing disappointment in Pickles despite the massive inversions in success between them.

Described by Pickles as a "staring, say-nothing weirdo," Calvert has received little to no characterization through the series, besides the instance he was seen in the episode Fatherklok to be disappointed in a young Pickles, telling him, "You belong in a garbage can." Pickles has said on multiple occasions that he has "no relationship" with his father "other than I hate him." Pickles says he regrets not staying at home beating the living shit out of his father for all the harsh words he said to him. He also mentions that he has forgotten his father's name and he's proud of that fact. Like the rest of Pickles' family, his last name is unknown as of Doomstar Requiem.

Though it is not verbally addressed, Pickles gets back in contact with his father in the episode Breakup Klok, when they attempt to start a winery business together after Dethklok's disbanding. He refers to his father as "buddy" rather than 'dad'. The venture is ultimately a failure when all attendees of their first tasting event are poisoned by the "unlicensed metabolic hormones" used to make the grapes grow faster and larger.
