Hank Russo is the husband of Rose Russo, the father of Jerry, Kelbo and Megan Russo, the paternal grandfather of Justin, Alex and Max Russo, and Theresa's father-in-law. He appears in Rock Around the Clock, where the Russos travel back to 1957 to warn Hank about Lenny Hune going to buy the building.
- His daughter-in-law, Theresa, called him Hank, but his name is said to be Duke in Hugh's Not Normous. It is possible that Duke or Hank is his middle name and he prefers to be called Hank.
- Max stated he pulls jelly beans out of his ear in the future, and Theresa states that in the future he actually eats them.
- He chose to put the Russo family lair in the freezer of the substation.
