Terry and his younger brother, Andy, lived happily with their father, Jeff Bogard, considered to be one of the greatest fighters of Southtown. Jeff trained in the style of Hakkyokuseiken under the orders of his master Tung Fu Rue. However, he had a partner named Geese Howard, who was more powerful than Jeff, but had evil ambitions. Seeing this, Tung Fu Rue decided to teach the secrets of his style to Jeff, who always wanted to surpass his skills constantly. This caused the rage of Geese, and vowed revenge. Years later, Geese became the most powerful man in Southtown due to his great criminal actions and many earnings. However, he never forgot the humilliation imposed on him, and one day, he murdered Jeff in combat. Terry and Andy, now orphans, decided to go separate ways and train in their own style and come back one day to exact revenge out of Geese. While Andy flyed over to Japan to learn the deadly art of Koppo-ken, Terry decided to stay in Southtown and face his destiny in the rough streets were the secrets of fighting are made.

Equipped with only his gloves given to him by his father and his eternal cap, Terry wanders the streets of Southtown, and begins to train himself in several martial arts, mixing it along with what he had learned from his father. Almost living near the edge, Terry manages to survive the hellbound streets of Southtown, and begins to adapt to it after many years of training and surviving. Terry grew up, and his combination of several martial arts made him a very dangerous opponent to consider.

Terry awaited the arrival of his brother, Andy, but when he arrived, he did not come alone. He had taken a friend, a Japanese kickboxer named Joe Higashi. The trio agreed to participate in the King of Fighters tournament, which Geese held each year to clean the path of any opposition. Terry entered, and soon began to show himself as the most dangerous menace to Geese. He totally plowed his way towards Billy, the champion put by Geese to defeat anybody who won the final match. After defeating Billy, Terry arrived with Geese at the top floor of his tower. Geese mocked Terry, saying he was still too young and weak to fight him. Terry vowed to exact revenge, and fought against Geese. However, unlike Andy, Terry did not fight just for revenge: he also fought because he liked to battle, and defeat worthy opponents, to enjoy the fight rather than feeling obligated to win. This, joined with some new techniques he had learned, impulsed Terry to victory, and on the final hit, knocked Geese out of the window, and sent him plumetting to his doom.

His blood filled with the sense of victory, Terry kept training to keep in shape. His victory had resounded in the whole world, far more than Southtown. This also happened to reach the ears of Wolfgang Krauser, a German noblesman who enjoyed the sense of fighting. He was excited to fight the man who defeated Geese Howard, but he did not know who the man was, so he began a quest around the world, beating all the fighters that could be this man. Terry was informed about him, and decided to give him a chance, went out to look for him. He met some new faces along the way, new fighters and new friends: Kim Kaphwan, the Tae Kwon Do justice fighter; Mai Shiranui, the red-haired bouncy ninja; Jubei Yamada, the Judo master. Fighting and learning a bit from everyone, came his faithful fight with Krauser. The battle was more than even, since both did not fight for personal feelings, but for the pleasure of fighting. The difference was that instead of fooling around with inferior fighters as Krauser did, Terry did progress in his trips, managing to channel all that experience into his techniques and defeating Krauser. Once again, Terry became a worldwide figure, and it seemed that nobody could stop him.

Of course, Terry was one of the first fighters to be invited to the new format of the King of Fighters tournament, which was taken by a new host. It introduced a new team battle mode, so Terry invited his brother, Andy, and Joe to accompany him. Ever since, the team that was to be known as the "Lonely Wolves" became one of the most powerful teams in the tournament. Although they never won the tournament, they always reached the finals, and Terry was always an excellent fighter, always overcoming himself. He always helped Kyo in his fights against Rugal and the Orochi clan. Terry retained his tag of a great fighter, since no fighter seems to close to his dedication and spirit. A true fighter, Terry seeks the next challenge...

Terry does not rest his fighting spirit during the last few years. Still waiting for the true combat to begin, Terry trains and fights every day in the lawless streets of Southtown. He is worried about his friend Kyo, nonetheless, who has been reported as missing ever since the last King of Fighters tournament ended. He is once again hurled into battle when he is one of the main guests to the 1999 King of Fighters tournament, and now accepts Mai as his new teammate (though he leaves to Andy the task of controlling her). During the last pace of the tournament, however, as Terry nears the underground base of the mysterious host, Krizalid, Terry senses a strange aura. Could it be Kyo's?! Before he could think any further, the whole passage begins to collapse. His partners manage to escape, but Terry refuses to leave his friend alone. The ruins fall to the ground shortly after, and none of the Lonely Wolves knows the fate of Terry. However, Terry still fights on the streets, always willing to take one anyone who challenges him, as he is the one and only "Lone Wolf"!

After his strict period of training, Terry finally returns to the fighting scene, ready to join his brother Andy, and eternal friend, Joe, in order to fight one more time in the King of Fighters tournament. However, now that Mai has gone to join her past friend Yuri Sakazaki, one partner was needed. Before they could even consider, Mary offered herself to become the new member of the Lonely Wolves. Terry assumes this tournament will be most interesting....

Much to Terry's surprise, the final battle is scheduled to be in Southtown, where it all began. Terry is suspicious about NESTS' actions in his hometown. Terry, who knows the city like the palm of his hand, leads the others to their meeting place: an abandoned factory in the industrial zone. Upon arrival, Terry notices a huge hustle around the factory. They look like soldiers, but are they good or evil? His answer soon arrives when the soldiers attack without warning. Terry has no problems in dealing with the trash with his incredible fighting skill. But the overwhelming number of troops forces Terry and the others to retreat inside the building.

Once inside, and while Terry is starting to have some fun, the whole factory begins to tremble. The mercenaries run away like scared children. From what he managed to hear, some sort of cannon has fired a destructive laser beam straight at Southtown! Terry aids his partners in the escape, but Terry himself is knocked by falling debris. Andy and Mary try to rescue him, but Terry urges them to escape, as there is no time left. Having said that, Terry remains in the building up until the final explosion...and destruction, of Southtown.

Nothing is known about Terry ever since, but he is still around...perhaps mourning the death of his beloved town, which, despite being a city filled with criminals and perverted intentions, he knows deep inside that Southtown never belonged to NESTS, but to those who fought for it. Now he helps Mary out in her investigation, but Terry knows more than anyone that it will take more than just harsh words to take down NESTS next time, but the strength of a hungry wolf!

Terry stays in Southtown, his beloved home city, as he tries to rebuild what was once left of his glorious town. It is painful for Terry to have to see his hometown reduced to ashes, but he knows that the city was already condemned ever since it gave in to NESTS. What Terry is worried about most is that he must take care of the orphans who now wander around the ruins of Southtown. He knows that he was once like them, and he must make up to them as a tribute to his late father, Jeff Bogard, who also helped him out when he was just a street urchin wandering around Southtown. He knows it is his sworn duty, since he has already taken a kid under his wing ever since he defeated Geese for the last time, 3 years ago....

After knowing that his children are sure and safe, Terry meets up with Mary, who also happened to be roaming around Southtown, following the tracks of NESTS. Terry is more than intent on taking NESTS down for what they did to Southtown, and he also knows for sure that Andy and Joe would soon show up to enter the next King of Fighters tournament. Terry knows that this time, he must fight for a lot more than just his pride as a fighter and his desire to encounter worthy opponents: he must for the fate of the world, which has once again been jeopardized by the evil ambition of NESTS.

The "Lone Wolf" once again shows his fangs as the King of Fighters tournament kicks off this year! His fists and power now aim towards the downfall of NESTS, and he won't rest until he has found ultimate justice! But, Terry knows that deep inside, the disaster of Southtown allowed him to appreciate his beloved ones a lot more than before: his younger brother Andy, his close friend Joe, and his dearest Mary. He also knows that he made many friends in the tournament, and for that, he should be grateful. For them, Terry fights to the very end, once again helping out inmensely in the final downfall of NESTS, and the defeat of Igniz, the CEO of NESTS, atop his own space station. The space base falls to the ocean back on Earth, but Terry does manage to escape, hoping that a whole new era of peace will finally dawn on their planet.

Terry, as his nickname "Lone Wolf" implies, is always alone, but he is a very good natured fellow. He always seems to be cool and calm, but in battle, he attacks with fury and determination. He has many friends, many of which he met in battle. He also likes to play with kids and meet with his brother Andy and remember the good old times. He and Blue Mary seem to be attracted to each other, but Terry always seems to lose her phone number! When Terry fights, he does not always seek to win, but to take something from the fight.
