In his Minotaur form Theodore was shown to be slim, muscular and very tall, as the height difference between him and Hank seemed to be a big difference. Along with his large horns and beast face, he wore armour that covered almost the whole of his body. In his human form he was a man of medium height with short hair.
He was well renowned for being a coward, being scared of anything, even being of afraid of transforming into a Incarnate and losing his life. Knowing he wouldn't last long on the battlefield, as he always put himself in constant danger. Hank taught him how to survive through out the Civil War. When the war ended, Theodore became paranoid, as when a child pointed a toy at him, he begun to start building a fortress. Once his fortress was built Theodore claimed he had to keep building to protect him, as he believed people were aiming for him from the shadows. As when in battle to slow down Hank's movements. Theodore was shown to have greatly took on board the advice given to him by his captain during the civil war, "only those who are prepared at all times can survive".
When Theodore views a flare in the sky, he's taken by surprise and realises it's the signal of the Pseudo-God Soldiers. When confronted by Hank, surprised to see his captain he claims he knew it was him who light the flare. Telling of how their unit was scattered, he asks him what he thinks of his fortress and questions where is the enemy is. When Hank tells him he's come to stop him, he's taken by surprise and questions if he's siding with the town's people, claiming he's his enemy. Telling about how he's grown strong and isn't afraid anymore. When cannonballs are dropped upon Hank, he avoids the attack and releases a flair, attempting to attack his head. Realising Hank's plan, he swings his axe into the ground and shatters it. Theodore mentions that only those who are prepared at all times can survive, as he made preparations to seal his movements.
As Theodore approaches him below and prepares to finish him. He is taken by surprise when Hank transforms into his werewolf form, telling him he's gone to far. When Theodore claims he doesn't want to become like the others, and questions what was he supposed to do. Hank approaches him and stabs him in the neck. After being stabbed, he's then caught up in an explosion which blows off his armour and knocks him down to the floor. Lying on the floor, he tells Hank he feels great as he isn't afraid of anything and that he can stop building, as well as it being nice to feel scared. Hank tells him that he's right and then kills him using his gun.
