The characters and/or events in the storyline depicted in this article have been changed, altered, added to, or erased from the main continuity.
Carl Tennyson is alternate version of Carl from the RAT timeline.
Carl is depicted as a new-age style parent who wants Ben to have his "freedom," insisting on being called "Carl," not "daddy," "dad," or "father," and letting Ben run off on mysterious adventures without asking questions. Carl wants Sandra to give Ben some freedom. He seems more laid back than Sandra, and is seen at least twice telling her to let Ben have his fun. For instance, near the end when Sandra tells him to not eat too much cheese, Carl says to "Let the kid live a little. Eat all the cheese you want, Ben!"
Carl seems to contradict Sandra when it comes to disciplining Ben, being more loose than stern, though like Sandra, he insisted to be called by his name.
