It was one of those spots in the early issues of Jonathan Hickman's Avengers that made me very happy. That Smasher was one Isabel Dare, and her grandfather was called Dan. Making her the grandchild of Dan Dare. We commented on it. It was great.
But in the collected edition, Smasher's name is now Isobel Kane.
Aw maaaan… But hang on. Dan Kane was Captain Terror, fought against Franco in the Spanish Civil War and with Captain America in World War II… and then met up with Cap in the modern day. Which makes subsequent scenes with Captain America make more sense.
Curiously, this change hasn't been made in the digital collected download. So if you still want the Dan Dare version, hurry!
