MoleAr is a supervillain who's incarcerated in Roxbury C. He's also a graduate mining engineer with a Master's degree and a Ph.D. from Texas A&M. He looks like a sterotypical "mild-mannered reporter," and has a history of non-violence.
He directs the digout from Roxbury C with Tennyo.[1]
MoleAr has the ability to manipulate rock and similar materials by touch—he was able to make the concrete which was trapping Tennyo to ooze like thick mud, freeing her, but he couldn't do the same to the metallic rebars. Similarly, he could push concrete and bedrock out of the way and form it into solid shapes during their escape from the ruined prison. His power is very well-suited for escaping from a regular prison, which probably explains why he was in Roxbury C.
