Hunting John Al
He at first comes to hunt John Al, the head of the local outlaws, so he could build an agency in the lands. However, when he asks Tom McCoinner for information about Al, Tom refuses to cooperate and therefore Byron declares war on him and his allies.
War against the civilians
He then took one of his enemies, Gustav De Fort'e as a hostage near the docks of Washington D.C near the marina area. He revealed that his purpose was to drown him so he could get hold of the evidence which Gustav has written against him. He then chokes Gustav and dumps his head a few times into the water, until he falls off the land and drowns.
He later went to battle the villagers, led by John Al, as he ordered his men to fire and obliterate the village's pub. As he tells his guards to show no mercy and to eliminate every outcast with blood on the walls, Tom McCoinner saves the day by killing most of his agents, just before Byron orders the latter to retreat until the very next day.
Later, it is revealed that Byron and The Agency actually work for no other benefactor then Colonel Samuels, who wants the mighty riches of Texas' land.
After a few more days go by, Agent Byron kills the city mayor of Dallas in order to eliminate the evidence, while John Al and his crew watch Byron committing these crimes in horror.
Edward Milton later went to Dallas in order to spy after Jeff Byron and recieve information for the gang, as he was secretly plotting to start destroying the city later. He told Tom that Byron gets his supplies from the CEO of the Exxon oil company Ronald Buston. However, as Milton, John Al and Tom reached their destination, they hid away and saw behind the scenes that Byron and Buston are planning to bomb up the village with dynamite. John shot Buston after Byron left, but Edward Milton stole the dynamite and secretly blew up Gizelle's parents and their mannor. Byron was held responsible for it at first, but Tom quickly realized that it was actually Milton whom bombed up the house in order to gain his revenge on The Agency and make the US citizens in general feel just like he felt, even betraying John Al's crew. However, Jeff was determined to have the village wiped off the map, and he still wanted to remove Tom McCoinner from his way. Just before he could shoot McCoinner however, Gizelle appeared and shot Agent Byron in the head.
Agent Byron is presented as a cruel, merciless and sadistic man of war and corruption. He is seen taking actions himself which are very harmful towards the weaker people who surround him. He seems to enjoy being on duty even if it means that he kills other people to succeed with his tasks. He is corrupt and is also shown to be very power hungry, as his intentions are to build a tower on the village land for The Agency even if he needs to kill every person in the village. He orders his guards to shoot with no mercy, and personally makes sure they are killed off one by one. That shows how sadistic and ruthless Byron really is.
