Max tennyson

Maxwell "Max" Tennyson aka Grandpa Max as his grandchildren call him, is the paternal grandfather of Ben, Gwen, Ken and Sunny. He is in his 60's (64-65 in Alien Force and 65-66 in Ultimate Alien), rather overweight and a bit slow at times, but with a keen sense for adventure and a strange taste in food -- the only topic on which Ben and Gwen never argue. Max ends up taking the kids on a Summer Vacation 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. The Rust Bucket is a replica of a GMC Classic Motor home. In the live-action films, Max Tennyson is portrayed by veteran actorLee Majors in Ben 10: Race Against Time, and by Barry Corbin inBen 10: Alien Swarm. here!
