Ben is a large, muscular Great Dane, and is mainly a light brown with black splotches around his eyes. He has a dark brown snout, and wears a red beaded collar.
He has cropped ears and a collar, showing his past as a pet dog. His collar is red, but for some reason it's portrayed a greenish gray in GDW anime.
Ben is a dog with great physical and mental strength. He has unusual endurance, bravery, wisdom and sense of honor.
He respects dogs with resilience and bravery. He is very impressed by Gin's skill and nature, but the younger dog is still quite young and Ben often guides him. Ben is willing to entrust Gin with the first platoon leader role after he loses his sight, knowing he would be a great leader.
Ben has a very kind heart. He has mentioned himself that he dislikes killing and tends to give the criminals another chance instead. He has often helped and saved other dogs. He saved the young Kai Brothers and took care of them until they could survive on their own. He also helped Akame escape after he was caged by his owner. Ben's owner seems to trust and understand his dog very well and it seems like that he sometimes lets Ben wander by himself.
Ben is at the times a bit comically under Cross's thumb and doesn't want to make her angry. Eventually, the two fall in love and have puppies together. While other dogs are unaware of her being pregnant at first, it seems that Cross told Ben about it. Ben wants to protect his family in the battle against Akakabuto no matter what. He is protective father and shows his pups affection.
In Ginga Densetsu Weed, Ben has turned completely blind and also senile from age. Cross takes good care of him. Sometimes he starts to wander, not realizing where he is going, and doesn't recognize things like he used to. Sometimes he might turn a bit angry or stubborn due to his inability to remember and understand things clearly.
In the GDW anime, his senility was turned more comical, while it has more sad and serious tone in the manga. Generally, his mind is more clear in the anime. Yet, he is oddly grumpy and aggressive in GDW anime, not matching his personality in manga.

After returning to his old owner and getting medical treatment, Ben recovered some of his sight so he could participate in the final battle.

Mukonga is so impressed that he lets them go to meet the wolf lord Reima.
Reima tells them that their true enemy is an evil wolf lord Gaia. It also turns out that Ben is the Geki warrior, meaning that he is a descendant of an original Hakkenshi Of Sirius and the true user of Geki Sentsūhi-Battōga. Ben accepts this but believes that Mukonga is the one who deserves the title. Ben is sad when Mukonga died and honors his memory.
When the army swims to Hokkaido to face Gaia's Empire, Ben suddenly starts to see again. This is thanks to Mukonga's Battouga which hit him on the right spot and slowly made his eyesight recover.
Ben fights the evil Geki user Bighorn and kills him after the wolf continues to use the title though Ben tells him that it's Mukonga's alone.
