Tyson is Heizō's best friend and one of the One-eyed Elder's followers.


He is red-brown and white mixed breed. He has black eyes and black ears.


He isn't a very good fighter, but like Heizō and the other Ou soldiers, he is very loyal to his leader, Orion and is always willing to be useful at any time. But he's still very fearfull and don't like to deal with villains and would even leave friends and family behind when he thinks he wouldn't be able to help them anyway. But if someone is talking sense to him he would actually oppose against villains sometimes, because he's not very strong-willed, but then really reluctantly, obsequious and fearful.

Ginga Densetsu Weed: Orion

After Orion left Heizo's pack to find his family, the One Eyed Elder sent Heizō and Tyson to follow him in case of any incident. Just as the old dog had predicted, Orion was attacked by a group of traveling dogs, lead by the Pit Bull Terrier, Ryō.

While Heizō distracted him and his followers, Tyson took Orion to a broken electric pole, where he could be safe. During the series, Tyson normally sticks around with his best friend.

Ginga: The Last Wars

Later, Akame runs to indicate that the Monsoon has attacked Ōuu. Tyson starts moving immediately with the pack. They are waiting in the mountains of the Kyoto to meet Yamabiko's packs, but after two days they decide to leave as early as the pre Ōuu. Orion and Yamabiko combine forces later and arrive at Nagano to join up with Unsai. Then, United Army dog then leaves towards the Ohu.

Tyson along with others watched Unsai get carried away for treatment.

Shortly after all of Monsoon's Kin are dead, he watches Akame fall unconscious due to his injuries. Even though, he is revived by Daisuke and Hidetoshi; Akame needs treatment badly and is taken away.

He and the other dogs regroup and are joined by Gin, who left Daisuke's care to check on them. Feeling defeated over their losses, the army spend their days and nights cuddled together for comfort before Andy, Yamabiko, Bon and Orion leave to find Sirius.

When morning comes, Tyson hears Kyōshirō chew Orion out for sending his friends away, and then watches the fight by Orion and Kyōshirō, even though the Kyōshirō lost. He saw Orion crying in tears, saying that he stayed behind for the sake of everyone because the Ohu Army needs a true leader.
