A Blizzard is Coming to Agents of SHIELD: The January 14 episode, titled "Seeds," will see Dylan Minnette guest starring as Donnie Gill -- whose supervillain name is Blizzard. Not many details are known, but according to the comics in which this character originated from (via ScreenCrush), Justin Hammer, who is also a villain from the Marvel universe, gave him the Blizzard suit. The official episode description says, "Coulson and May uncover startling information about Skye's past, while the team is swept into a storm at SHIELD Academy." We can all assume said storm is caused by the supervillain himself.
