Dr. Charles Lightning is a minfigure in the Adventurers theme. He is also known as Dr. Kilroy. He is one of the main characters and has been in every segment of the theme. He has had multiple names in different countries, as have Johnny Thunder and Pippin Read. He is a rank 4 networker on my lego network.

He has traveled all over the world hunting for fossils and dinosaur bones and has made many magnificent discoveries. When he's not off on a dig, he likes to help out in Jen Juniper's greenhouse.
