Dynamo had five superhuman abilities: flight, super strength, telepathy, shapeshifting, and laser/x-ray/telescopic vision, and maintained a secret headquarters beneath an industrial pier.

His death caused an outpouring of grief in the Image universe superhero community, all or most of which was in attendance at his funeral, including the Savage Dragon, Shadowhawk II, and Invincible.

In sorting through his personal effects, Warner discovered his little black book, which was filled with detailed information on countless incidents of infidelity on his part.

Although devastated by the extent of her late husband's indiscretions, Warner was faced with the problem of Dynamo's numerous enemies, who would now take advantage of Tower City in his absence.

Donning costumes to conceal their identities, the five of them carry on his legacy as the superhero team the Dynamo 5, while coming to terms with learning about the father they never knew, and the four new half-siblings they each now have.

Although the five are unaware that Warner is a former agent of F.L.A.G., she is determined to mold them not only into a team, but into a family as well, and functions as their mentor and “unofficial sixth member”, calling the shots from the same headquarters once used by Captain Dynamo, and keeping in constant remote contact with them during their missions.

While Captain Dynamo boasted a public image as the greatest superhero in the world, in private, he was a habitual womanizer who cheated on his wife, Maddie Warner, and fathered numerous children, even when it compromised his crime-fighting duties.
