Hank is the Kent family terrier dog loyal to Clark Kent.
When Clark was 17, a tornado struck Smallville and as Jonathan, Clark, and Martha got out to investigate, they had to take nearby cover under a overpass. Realizing they had left Hank behind, Jonathan bravely went back to get him, as a car landed on top of the vehicle, trapping both of them. Jonathan managed to open a door for Hank to escape, as the tornado eventually swept Jonathan away to his death.
- In childrens' books based on Man of Steel, the dog's name was Shelby, just as the family dog on the TV Series Smallville.
