Maxwell "Max" Tennyson, or Grandpa Max as his grandchildren call him, is the paternal grandfather of Ben, Gwen, Kenny and father of Carl Tennyson and Frank Tennyson. He is a fairly overweight man in his late 60's with a keen sense for adventure and a strange taste in strange food. Max ends up taking the kids on a Summer Vacations' Roadtrip across the United States. Much to Ben's annoyance, Ben discovers that Gwen is joining them. Max travels in a motor home nicknamed the Rust Bucket, which he has modified with advanced technology.
Max is a semi-retired legendary Plumber, is the mentor of Ben, Gwen and Kevin and the Plumber Helpers.
Max is a tall, stocky man with broad, muscular arms. He wears a white shirt, covered by a red button up shirt with a floral design. He has grey hair and blue pants as well as black shoes.
